[#3521]: Collator side changes for elastic scaling

Parachain teams wishing to utilize the benefits of elastic scaling will need to upgrade their collator code to include these changes.

[#3302]: Collator protocol changes for elastic scaling

This PR introduces changes to the collator protocol to support elastic scaling. Namely, a new variant added to the collation response to include parent head-data along with the collation. Currently, the new variant is not being used.

[#3950]: Add ClaimQueue wrapper

Intoduces a new wrapper type: ClaimQueueSnapshot. It contains a snapshot of the ClaimQueue at an arbitrary relay chain block. Two methods are exposed to allow access to the claims at specific depths.

[#3795]: Enable collators to build on multiple cores

Introduces a CoreIndex parameter in SubmitCollationParams. This enables the collators to make use of potentially multiple cores assigned at some relay chain block. This extra parameter is used by the collator protocol and collation generation subsystems to forward the collation to the approapriate backing group.

[#3580]: Expose ClaimQueue via a runtime api and consume it in collation-generation

Creates a new runtime api exposing the ClaimQueue from scheduler pallet. Consume the api in collation generation (if available) by getting what's scheduled on a core from the ClaimQueue instead of from next_up_on_available (from AvailabilityCores runtime api).

[#3854]: Export unified ParachainHostFunctions from cumulus-client-service

Exports ParachainHostFunctions to have a bundled version of SubstrateHostFunctions and cumulus_primitives_proof_size_hostfunction::storage_proof_size::HostFunctions. This increases discoverability and makes it more obvious that they should be used together in parachain nodes.

[#3479]: Elastic scaling: runtime dependency tracking and enactment

Adds support in the inclusion and paras_inherent runtime modules for backing and including multiple candidates of the same para if they form a chain.

Changelog for Runtime Dev

[#3817]: Parachain Runtime API Implementations into mod apis Refactoring

This PR introduces a refactoring to the runtime API implementations within the parachain template project. The primary changes include enhancing the visibility of RUNTIME_API_VERSIONS to pub in impl_runtime_apis.rs, centralizing API implementations in a new apis.rs file, and streamlining lib.rs. These changes aim to improve project structure, maintainability, and readability.

Key Changes:

• RUNTIME_API_VERSIONS is now publicly accessible, enhancing module-wide visibility.
• Introduction of apis.rs centralizes runtime API implementations, promoting a cleaner and more navigable project structure.
• The main runtime library file, lib.rs, has been updated to reflect these structural changes, removing redundant API implementations and simplifying runtime configuration by pointing VERSION to the newly exposed RUNTIME_API_VERSIONS from apis.rs.

Motivations:

• Improved Project Structure: Centralizing API implementations offers a more organized and understandable project layout.
• Enhanced Readability: The refactoring efforts aim to declutter lib.rs, facilitating easier comprehension for new contributors.

[#3722]: Fix kusama 0 backing rewards when entering active set

This PR fixes getting 0 backing rewards the first session when a node enters the active set.

[#3607]: XCM fee payment API

A runtime API was added for estimating the fees required for XCM execution and delivery. This is the basic building block needed for UIs to accurately estimate fees. An example implementation is shown in the PR. Ideally it's simple to implement, you only need to call existing parts of your XCM config. The API looks like so:

      fn query_acceptable_payment_assets(xcm_version: Version) -> Result<Vec<VersionedAssetId>, Error>;
      fn query_xcm_weight(message: VersionedXcm<Call>) -> Result<Weight, Error>;
      fn query_weight_to_asset_fee(weight: Weight, asset: VersionedAssetId) -> Result<u128, Error>;
      fn query_delivery_fees(destination: VersionedLocation, message: VersionedXcm<()>) -> Result<VersionedAssets, Error>;

The first three relate to XCM execution fees, given an XCM, you can query its weight, then which assets are acceptable for buying weight and convert weight to a number of those assets. The last one takes in a destination and a message you want to send from the runtime you're executing this on, it will give you the delivery fees.

[#3761]: Snowbridge: Synchronize from Snowfork repository

This PR improves the beacon client to send the execution header along with the message as proof and removes the verification and storing of all execution headers. If the AH sovereign account is depleted and relayer rewards cannot be paid, the message should still be processed.

[#3792]: [pallet-xcm] fix transport fees for remote reserve transfers

This PR fixes pallet_xcm::transfer_assets and pallet_xcm::limited_reserve_transfer_assets extrinsics for transfers that need to go through remote reserves. The fix is adding a SetFeesMode { jit_withdraw: true } instruction before local execution of InitiateReserveWithdraw so that delivery fees are correctly charged by the xcm-executor. Without this change, a runtime that has implemented delivery fees would not be able to execute remote reserve transfers using these extrinsics.

[#3808]: Fix spelling mistakes in source code

Public crate changes:

• The public trait RuntimeParameterStore in substrate/frame/support had the associated type renamed from AggregratedKeyValue to AggregatedKeyValue.
• The public trait AggregratedKeyValue in substrate/frame/support was similarly renamed to AggregatedKeyValue.
• The public methods test_versioning and test_versioning_register_only of the TestApi trait in substrate/primitives/runtime-interface/test-wasm had the spelling of versionning changed to versioning.
• The public functions read_trie_first_descendant_value and read_child_trie_first_descendant_value in substrate/primitives/trie had the spelling of descedant changed to descendant.

[#3714]: Handle legacy lease swaps on coretime

When a registar::swap extrinsic is executed it swaps two leases on the relay chain but the broker chain never knows about this swap. This change notifies the broker chain via a XCM message for a swap so that it can update its state.

[#3740]: Removed pallet::getter usage from Beefy and MMR pallets

This PR removes pallet::getter usage from pallet-beefy, pallet-beefy-mmr and pallet-mmr, and updates dependant code and runtimes accordingly. The syntax StorageItem::<T, I>::get() should be used instead.

[#3927]: pallet-xcm: deprecate transfer extrinsics without weight limit

pallet-xcm's extrinsics teleport_assets and reserve_transfer_assets have been marked as deprecated. Please change their usage to the limited_teleport_assets and limited_reserve_transfer_assets, respectively; or use the generic/flexible transfer_assets extrinsic.

[#3738]: Removed pallet::getter usage from pallet-alliance

This PR removes pallet::getter usage from pallet-alliance, and updates dependant code accordingly. The syntax StorageItem::<T, I>::get() should be used instead.

[#3190]: Fix algorithmic complexity of the on-demand scheduler.

Improves on demand performance by a significant factor. Previously, having many on-demand cores would cause really poor blocktimes due to the fact that for each core the full order queue was processed. This allows for increasing the max size of the on-demand queue if needed. At the same time, the spot price for on-demand is now checked prior to every order, ensuring that economic backpressure will be applied.

[#3654]: Remove experimental feature from pallet-aura

The experimental feature in pallet-aura, previously used to gate different experimental changes, became redundant with the introduction of the async backing which relies on the mentioned changes, therefore, it is removed.

[#3718]: Deprecate scheduler traits v1 and v2

Add #[deprecated] attribute to scheduler traits v1 and v2 to deprecate old versions

[#3471]: removed pallet::getter from cumulus pallets

This PR removes all the pallet::getter usages from cumulus pallets, and updates depdendant runtimes accordingly. The ParaId can be retrieved using <ParachainInfo as Get<ParaId>>::get(). For other storage items, the syntax StorageItem::<T, I>::get() should be used instead.

[#3754]: Migrates Westend to Runtime V2

This PR migrates Westend from construct_runtime to Runtime V2 as introduced in https://github.com/paritytech/polkadot-sdk/pull/1378

[#3350]: removed pallet::getter from Pallet AURA

This PR removes all the declarations of macro pallet::getter in the Pallet AURA and replaces the use of storage getter functions authorities() & current_slot() with StorageItem::get() API across the crates as listed bellow. The purpose is to discourage developers to use this macro, that is currently being removed and soon will be deprecated.

[#3749]: pallet-xcm: deprecate execute and send in favor of execute_blob and send_blob

pallet-xcm's extrinsics execute and send have been marked as deprecated. Please change their usage to the new execute_blob and send_blob. The migration from the old extrinsic to the new is very simple. If you have your message xcm: VersionedXcm<Call>, then instead of passing in Box::new(xcm) to both execute and send, you would pass in xcm.encode().try_into() and handle the potential error of its encoded length being bigger than MAX_XCM_ENCODED_SIZE. pallet-contracts takes the XCM encoded now as well. It follows the same API as execute_blob and send_blob.

[#3835]: migrations: prevent accidentally using inner unversioned migration instead of VersionedMigration

Currently, it is possible to accidentally use inner unversioned migration instead of VersionedMigration since both implement OnRuntimeUpgrade. With this change, we make it clear that Inner is not intended to be used directly. It is achieved by bounding Inner to new trait UncheckedOnRuntimeUpgrade, which has the same interface as OnRuntimeUpgrade, but can not be used directly for runtime upgrade migrations.

This change will break all existing migrations passed to VersionedMigration. Developers should simply change those migrations to implement UncheckedOnRuntimeUpgrade instead of OnRuntimeUpgrade.

Example:

--- a/path/to/migration.rs
+++ b/path/to/migration.rs
@@ -1,7 +1,7 @@
-impl<T: Config> OnRuntimeUpgrade for MigrateVNToVM<T> {
+impl<T: Config> UncheckedOnRuntimeUpgrade for MigrateVNToVM<T> {
    fn on_runtime_upgrade() -> Weight {
        // Migration logic here
        // Adjust the migration logic if necessary to align with the expectations
        // of new `UncheckedOnRuntimeUpgrade` trait.
        0
    }
}

[#3616]: Benchmarking pallet V2 syntax extension: pov_mode attribute

Adds the pov_mode attribute from the V1 benchmarking syntax to the V2 syntax. This allows to override the default PoV mode (MaxEncodedLen) to either Measured or Ignored. It can be overridden for a whole benchmark, a key prefix of a specific key itself.

Example syntax looks like this:

#[benchmark(pov_mode = Measured {
  Pallet: Measured,
  Pallet::Storage: MaxEncodedLen,
})]
fn do_some() {
  ..
}

[#3844]: Add the ability for MessageQueue to process enqueued messages on idle

Add the option to use remaining weight on idle for processing enqueued messages. This will increase the chances of the messages enqueued during inherent extrinsics to be processed in the same block. New config types is added on the message-queue Config trait:

• IdleMaxServiceWeight

example: rust parameter_types! { // The maximum weight to be used from remaining weight for processing enqueued messages on idle pub const IdleMaxServiceWeight: Weight = Some(Weight); } type IdleMaxServiceWeight = IdleMaxServiceWeight; // or `()` to not use this feature

[#3696]: Add HRMP notification handlers to the xcm-executor

Adds optional HRMP notification handlers to the xcm-executor. These handlers are 3 new config types on the xcm-executor Config trait:

• HrmpNewChannelOpenRequestHandler
• HrmpChannelAcceptedHandler
• HrmpChannelClosingHandler

The traits of these config types are implemented on tuples, and on () for the default case.

[#3302]: Collator protocol changes for elastic scaling

Validators are required to upgrade to this version before collators in order to support the elastic scaling of parachains.

[#3808]: Fix spelling mistakes in source code

Some spelling mistakes in log output, error messages and tracing (prometheus/grafana) have been fixed.

[#3961]: Added support for coretime-kusama/polkadot and people-kusama/polkadot

The support for running coretime-kusama and people-kusama collators with polkadot-parachain-bin have been added.

Changelog for Runtime User

[#3341]: Fix schedule_code_upgrade when called by the owner/root

Fixes schedule_code_upgrade when being used by the owner/root. The call is used for manually upgrading the validation code of a parachain on the relay chain. It was failing before because the relay chain waited for the parachain to make progress. However, this call is mostly used for when a parachain are bricked which means that they are not able anymore to build any blocks. The fix is to schedule the validation code upgrade and then to enact it at the scheduled block. The enacting happens now without requiring the parachain to make any progress.

[#3849]: Unrequest a pre-image when it failed to execute

When a referenda finished the proposal will be scheduled. When it is scheduled, the pre-image is requested. The pre-image is unrequested after the proposal was executed. However, if the proposal failed to execute it wasn't unrequested. Thus, it could not be removed from the on-chain state. This issue is now solved by ensuring to unrequest the pre-image when it failed to execute.

[#3438]: Pools: Make PermissionlessWithdraw the default claim permission

Makes permissionless withdrawing the default claim permission, giving any network participant access to claim pool rewards on member's behalf, by default.

[#3706]: Extrinsic to restore corrupted staking ledgers

This PR adds a new extrinsic Call::restore_ledger gated by StakingAdmin origin that restores a corrupted staking ledger. This extrinsic will be used to recover ledgers that were affected by the issue discussed in https://github.com/paritytech/polkadot-sdk/issues/3245. The extrinsic will re-write the storage items associated with a stash account provided as input parameter. The data used to reset the ledger can be either i) fetched on-chain or ii) partially/totally set by the input parameters of the call.

Changes introduced:

• Adds Call::restore_ledger extrinsic to recover a corrupted ledger;
• Adds trait frame_support::traits::currency::InspectLockableCurrency to allow external pallets to read current locks given an account and lock ID;
• Implements the InspectLockableCurrency in the pallet-balances.
• Adds staking locks try-runtime checks (https://github.com/paritytech/polkadot-sdk/issues/3751)

[#3850]: Detect incorrect pre-image length when submitting a referenda

When submitting a referenda the proposal is passed as argument. The proposal is most of the time a reference to a pre-image and which also contains the length of the pre-image. This pull request adds some logic to check that if the pre-image already exists and if it exists, it ensures that the length is passed correctly. This prevents that the referenda can not be executed because of a mismatch of this length.

[#3749]: pallet-xcm: deprecate execute and send in favor of execute_blob and send_blob

pallet-xcm has a new pair of extrinsics, execute_blob and send_blob.These are meant to be used instead of execute and send, which are now deprecated and will be removed eventually. These new extrinsics just require you to input the encoded XCM. There's a new utility in PolkadotJS Apps for encoding XCMs you can use: https://polkadot.js.org/apps/#/utilities/xcm Just pass in the encoded XCM to the new extrinsics and you're done.

pallet-contracts takes the XCM encoded now as well. It follows the same API as execute_blob and send_blob.

[#3246]: Try State Hook for Beefy.

Invariants for storage items in the beefy pallet. Enforces the following Invariants:

1. Authorities should not exceed the MaxAuthorities capacity.
2. NextAuthorities should not exceed the MaxAuthorities capacity.
3. ValidatorSetId must be present in SetIdSession.

This release contains the changes from polkadot-v1.8.0 to polkadot-v1.9.0.

Changelog

Changelog for Node Dev

[#3187]: Retrying an execution on failed runtime construction

If a runtime construction error happened during the execution request, then the artifact is re-prepared and the execution request is retried at most once. See also the related issue.

[#3233]: provisioner: allow multiple cores assigned to the same para

Enable supplying multiple backable candidates to the paras_inherent pallet for the same paraid.

[#3447]: Use generic hash for runtime wasm in resolve_state_version_from_wasm

Changes the runtime hash algorithm used in resolve_state_version_from_wasm from DefaultHasher to a caller-provided one (usually HashingFor<Block>). Fixes a bug where the runtime wasm was being compiled again when it was not needed, because the hash did not match.

Changelog for Node Operator

[#3523]: Fix crash of synced parachain node run with --sync=warp

Fix crash of SyncingEngine when an already synced parachain node is run with --sync=warp (issue https://github.com/paritytech/polkadot-sdk/issues/3496). The issue manifests itself by errors in the logs:

[Parachain] Cannot set warp sync target block: no warp sync strategy is active.
[Parachain] Failed to set warp sync target block header, terminating `SyncingEngine`.

Followed by a stream of messages:

[Parachain] Protocol command streams have been shut down

[#3231]: Allow parachain which acquires multiple coretime cores to make progress

Adds the needed changes so that parachains which acquire multiple coretime cores can still make progress. Only one of the cores will be able to be occupied at a time. Only works if the ElasticScalingMVP node feature is enabled in the runtime and the block author validator is updated to include this change.

[#3510]: Fix multi-collator parachain transition to async backing

The dynamic Aura slot duration, introduced in PR#3211, didn't take the block import pipeline into account. The result was the parachain backed by multiple collators not being able to keep producing blocks after its runtime was upgraded to support async backing, requiring to restart all the collator nodes. This change fixes the issue, introducing the dynamic Aura slot duration into the block import pipeline.

[#3504]: add prometheus label "is_rate_limited" to rpc calls

This PR adds a label "is_rate_limited" to the prometheus metrics "substrate_rpc_calls_time" and "substrate_rpc_calls_finished" than can be used to distinguish rate-limited RPC calls from other RPC calls. Because rate-limited RPC calls may take tens of seconds.

Changelog for Runtime Dev

[#3491]: Remove Deprecated OldWeight

Removed deprecated sp_weights::OldWeight type. Use [weight_v2::Weight] instead.

[#3002]: PoV Reclaim Runtime Side

Adds a mechanism to reclaim proof size weight.

1. Introduces a new SignedExtension that reclaims the difference between benchmarked proof size weight and actual consumed proof size weight.
2. Introduces a manual mechanism, StorageWeightReclaimer, to reclaim excess storage weight for situations that require manual weight management. The most prominent case is the on_idle hook.
3. Adds the storage_proof_size host function to the PVF. Parachain nodes should add it to ensure compatibility.

To enable proof size reclaiming, add the host storage_proof_size host function to the parachain node. Add the StorageWeightReclaim SignedExtension to your runtime and enable proof recording during block import.

[#3378]: Remove deprecated GenesisConfig

Removes deprecated type GenesisConfig, it was replaced by RuntimeGenesisConfig on May 24 of 2023. The type GenesisConfig was deprecated on May 24 of 2023 #14210

[#1554]: Runtime Upgrade ref docs and Single Block Migration example pallet

frame_support::traits::GetStorageVersion::current_storage_version has been renamed frame_support::traits::GetStorageVersion::in_code_storage_version. A simple find-replace is sufficient to handle this change.

[#3456]: Removed pallet::getter usage from pallet-collective

This PR removes pallet::getter usage from pallet-collective, and updates dependant code accordingly. The syntax StorageItem::<T, I>::get() should be used instead.

[#1781]: Multi-Block-Migrations, poll hook and new System Callbacks

The major things that this MR touches are:

Multi-Block-Migrations: pallet-migrations is introduced that can be configured in the System of a runtime to act as multi-block migrator. The migrations pallet then in turn receives the list of MBMs as config parameter. The list of migrations can be an aggregated tuple of SteppedMigration trait implementation.
It is paramount that the migrations pallet is configured in System once it is deployed. A test is in place to double check this.

To integrate this into your runtime, it is only necessary to change the return type of initialize_block to RuntimeExecutiveMode. For extended info please see https://github.com/paritytech/polkadot-sdk/pull/1781.

poll: a new pallet hook named poll is added. This can be used for places where the code that should be executed is not deadline critical. Runtime devs are advised to skim their usage of on_initialize and on_finalize to see whether they can be replace with poll. poll is not guaranteed to be called each block. In fact it will not be called when MBMs are ongoing.

System Callbacks: The system pallet gets five new config items - all of which can be safely set to () as default. They are:

• SingleBlockMigrations: replaces the Executive now for configuring migrations.
• MultiBlockMigrator: the pallet-migrations would be set here, if deployed.
• PreInherents: a hook that runs before any inherent.
• PostInherents: a hook to run between inherents and poll/MBM logic.
• PostTransactions: a hook to run after all transactions but before on_idle.

[#3377]: Permissioned contract deployment

This PR introduces two new config types that specify the origins allowed to upload and instantiate contract code. However, this check is not enforced when a contract instantiates another contract.

[#3532]: Remove deprecated trait Store

The deprecated trait Store feature has been removed from the codebase. Please remove usages of generate_store macro from your pallets and access the storage through generics. For example, <Self as Store>::StoredRange::mutate will need to be updated to StoredRange::<T>::mutate.

[#2393]: [XCMP] Use the number of 'ready' pages in XCMP suspend logic

Semantics of the suspension logic in the XCMP queue pallet change from using the number of total pages to the number of 'ready' pages. The number of ready pages is now also exposed by the MessageQueue pallet to downstream via the queue footprint.

[#3505]: Removes as [disambiguation_path] from the required syntax in derive_impl

This PR removes the need to specify as [disambiguation_path] for cases where the trait definition resides within the same scope as default impl path.

For example, in the following macro invocation

#[derive_impl(frame_system::config_preludes::TestDefaultConfig as frame_system::DefaultConfig)]
impl frame_system::Config for Runtime {
  ...
}

the trait DefaultConfig lies within the frame_system scope and TestDefaultConfig impls the DefaultConfig trait.

Using this information, we can compute the disambiguation path internally, thus removing the need of an explicit specification:

#[derive_impl(frame_system::config_preludes::TestDefaultConfig)]
impl frame_system::Config for Runtime {
  ...
}

In cases where the trait lies outside this scope, we would still need to specify it explicitly, but this should take care of most (if not all) uses of derive_impl within FRAME's context.

[#3460]: Repot all templates

This PR moves all templates into a single folder in the polkadot-sdk repo (/templates) and unifies their crate names as well. Most notably, the crate name for what was formerly known as node-template is no solochain-template-node. The other two crates in the template are consequently called: solochain-runtime-template and pallet-solochain-template. The other two template crate names follow a similar patter, just replacing solochain with parachain or minimal.

This PR is part of a bigger step toward automating the template repositories, see the following: https://github.com/paritytech/polkadot-sdk/issues/3155

[#3643]: Fix weight refund for pallet_collator_selection::set_candidacy_bond

This PR implements the weight refund of pallet_collator_selection::set_candidacy_bond to account for no iterations over the candidate list when the candidacy bond is decreased.

[#3665]: Revert "FRAME Create TransactionExtension as a replacement for SignedExtension (#2280)"

This PR reverts the PR which introduced TransactionExtension to replace SignedExtension.

[#3371]: removed pallet::getter from example pallets

This PR removes all the pallet::getter usages from the template pallets found in the Substrate and Cumulus template nodes, and from the Substrate example pallets.
The purpose is to discourage developers to use this macro, that is currently being removed and soon will be deprecated.

[#3574]: Generate test functions for each benchmark with benchmarking v2

This PR fixes an issue where using impl_benchmark_test_suite macro within modules that use the benchmarking v2 macros (#[benchmarks] and #[instance_benchmarks]) always produced a single test called test_benchmarks instead of a separate benchmark test for every benchmark (noted with the #[benchmark] macro).

By using this macro from now on, new tests will be created named test_benchmark_{name} where name is the name of the benchmark function. Those tests will be nested inside the module intended for benchmark functions.

Also, when using impl_benchmark_test_suite inside the module, the import of such marco will not be necessary, so any explicit import of it will be marked as unused, the same way it works for v1 macros so far.

[#3453]: [pallet-nomination-pools]: chill is permissionless if depositor's stake is less than min_nominator_bond

Nomination pools currently have an issue whereby member funds cannot be unbonded if the depositor bonded amount is less than MinNominatorBond. This PR makes the chill function permissionless if this condition is met. Consequently, nominate function also checks for depositor to have at least MinNominatorBond, and returns MinimumBondNotMet error if not.

[#3606]: [pallet_contracts] mark lock/unlock_delegate_dependency as stable

Lock and unlock delegate dependency are stable now, so we can mark them as such.

[#3589]: Removed pallet::getter usage from pallet-im-online

This PR removes pallet::getter usage from pallet-im-online, and updates dependant code accordingly. The syntax StorageItem::<T, I>::get() should be used instead.

[#3411]: add Encointer as trusted teleporter for Westend

add Encointer as trusted teleporter for Westend with ParaId 1003

[#3454]: Introduce storage attr macro #[disable_try_decode_storage] and set it on System::Events and ParachainSystem::HostConfiguration

Allows marking storage items with #[disable_try_decode_storage], which disables that storage item from being decoded during try_decode_entire_state calls.

Applied the attribute to System::Events to close https://github.com/paritytech/polkadot-sdk/issues/2560. Applied the attribute to ParachainSystem::HostConfiguration to resolve periodic issues with it.

[#1378]: Construct Runtime V2 - An outer macro approach to define the runtime

Introduces #[frame_support::runtime] that can be attached to a mod to define a runtime. The items in this mod can be attached to the following attributes to define the key components of the runtime.

1. #[runtime::runtime] attached to a struct defines the main runtime
2. #[runtime::derive] attached to the runtime struct defines the types generated by the runtime
3. #[runtime::pallet_index] must be attached to a pallet to define its index
4. #[runtime::disable_call] can be optionally attached to a pallet to disable its calls
5. #[runtime::disable_unsigned] can be optionally attached to a pallet to disable unsigned calls
6. A pallet instance can be defined as TemplateModule: pallet_template<Instance> An optional attribute can be defined as #[frame_support::runtime(legacy_ordering)] to ensure that the order of hooks is same as the order of pallets (and not based on the pallet_index). This is to support legacy runtimes and should be avoided for new ones.

[#3636]: [pallet_broker] Fix Linear::adapt_price behavior at zero

This fixes the behaviour of Linear which is the default implementation of the AdaptPrice trait in the broker pallet. Previously if cores were offered but not sold in only one sale, the price would be set to zero and due to the logic being purely multiplicative, the price would stay at 0 indefinitely.

[#3540]: [pallet-contracts] Only allow non-deterministic code to be uploaded with Determinism::Relaxed

The upload_code extrinsic, will now only allow non-deterministic code to be uploaded with the Determinism::Relaxed flag. This prevent an attacker from uploading "deterministic" code with the Determinism::Relaxed flag, preventing the code to be instantiated for on-chain execution.

[#3403]: Add claim_assets extrinsic to pallet-xcm

There's a new extrinsic in pallet-xcm that needs a new configuration item for its benchmarks. It's a simple function in pallet_xcm::benchmarking::Config, get_asset, that returns a valid asset handled by the AssetTransactor of the chain. If you're already using pallet-xcm-benchmarks, then you already have this function there and can just copy and paste it.

[#3412]: [FRAME] Add genesis test and remove some checks

The construct_runtime macro now generates a test to assert that all GenesisConfigs of all pallets can be build within the runtime. This ensures that the BuildGenesisConfig runtime API works. Further, some checks from a few pallets were removed to make this pass.

[#3324]: Fix weight calculation and event emission in pallet-membership

Bug fix for the membership pallet to use correct weights. Also no event will be emitted anymore when change_key is called with identical accounts.

[#3513]: Fix call enum's metadata regression

This PR fixes an issue where in the metadata of all FRAME-based chains, the documentation for all extrinsic/call/transactions has been replaced by a single line saying "see Pallet::name".

Many wallets display the metadata of transactions to the user before signing, and this bug might have affected this process.

Changelog for Runtime User

[#3403]: Add claim_assets extrinsic to pallet-xcm

There's a new extrinsic in pallet-xcm for claiming assets. This means that if your assets ever get trapped while teleporting or doing reserve asset transfers, you can easily claim them by calling this new extrinsic.

[#3639]: Prevents staking controllers from becoming stashes of different ledgers; Ensures that no ledger in bad state is mutated.

This PR introduces a fix to the staking logic which prevents an existing controller from bonding as a stash of another ledger, which lead to staking ledger inconsistencies down the line. In addition, it adds a few (temporary) gates to prevent ledgers that are already in a bad state from mutating its state.

In summary:

• Checks if stash is already a controller when calling Call::bond and fails if that's the case;
• Ensures that all fetching ledgers from storage are done through the StakingLedger API;
• Ensures that a Error::BadState is returned if the ledger bonding is in a bad state. This prevents bad ledgers from mutating (e.g. bond_extra, set_controller, etc) its state and avoid further data inconsistencies.
• Prevents stashes which are controllers or another ledger from calling set_controller, since that may lead to a bad state.
• Adds further try-state runtime checks that check if there are ledgers in a bad state based on their bonded metadata.

This release contains the changes from polkadot-v1.7.2 to polkadot-v1.8.0.

Changelog

Changelog for Node Dev

[#3395]: benchmarking-cli pallet subcommand: refactor --list and add --all option

pallet subcommand's --list now accepts two values: "all" and "pallets". The former will list all available benchmarks, the latter will list only pallets. Also adds --all to run all the available benchmarks and --no-csv-header to omit the csv-style header in the output. NOTE: changes are backward compatible.

[#3079]: Implement transaction_unstable_broadcast and transaction_unstable_stop

A new RPC class is added to handle transactions. The transaction_unstable_broadcast broadcasts the provided transaction to the peers of the node, until the transaction_unstable_stop is called. The APIs are marked as unstable and subject to change in the future. To know if the transaction was added to the chain, users can decode the bodies of announced finalized blocks. This is a low-level approach for transactionWatch_unstable_submitAndWatch.

[#3160]: prospective-parachains: allow requesting a chain of backable candidates

Enable requesting a chain of multiple backable candidates. Will be used by the provisioner to build paras inherent data for elastic scaling.

[#3244]: Make the benchmark pallet command only require a Hasher

Currently the benchmark pallet command requires a Block type, while only using its hasher. Now this is changed to only require the Easher. This means to use HashingFor<Block> in the place where Block was required. Example patch for your node with cmd being BenchmarkCmd::Pallet(cmd):

- cmd.run::<Block, ()>(config)
+ cmd.run::<HashingFor<Block>, ()>(config)

[#3308]: Parachains-Aura: Only produce once per slot

With the introduction of asynchronous backing the relay chain allows parachain to include blocks every 6 seconds. The Cumulus Aura implementations, besides the lookahead collator, are building blocks when there is a free slot for the parachain in the relay chain. Most parachains are still running with a 12s slot duration and not allowing to build multiple blocks per slot. But, the block production logic will be triggered every 6s, resulting in error logs like: "no space left for the block in the unincluded segment". This is solved by ensuring that we don't build multiple blocks per slot.

[#3166]: Expose internal functions used by spawn_tasks

This allows to build a custom version of spawn_tasks with less copy-paste required

Changelog for Node Operator

[#3358]: Do not stall finality on spam disputes

This PR fixes the issue that periodically caused finality stalls on Kusama due to disputes happening there in combination with disputes spam protection mechanism. See: https://github.com/paritytech/polkadot-sdk/issues/3345

[#3301]: rpc server add rate limiting.

Add rate limiting for RPC server which can be utilized by the CLI --rpc-rate-limit <calls per minute> The rate-limiting is disabled by default.

[#3230]: rpc server remove prometheus metrics substrate_rpc_requests_started/finished and refactor WS ping/pongs.

This PR updates the rpc server library to jsonrpsee v0.22 to utilize new APIs.

Breaking changes:

• Remove prometheus RPC metrics substrate_rpc_requests_started and substrate_rpc_requests_finished.
• The RPC server now disconnects inactive peers that didn't acknowledge WebSocket pings more than three times in time.

Added:

• Add prometheus RPC substrate_rpc_sessions_time to collect the duration for each WebSocket session.

[#3364]: rpc server expose batch request configuration

Add functionality to limit RPC batch requests by two new CLI options: --rpc-disable-batch-request - disable batch requests on the server --rpc-max-batch-request-len - limit batches to LEN on the server

[#3435]: Fix BEEFY-related gossip messages error logs

Added logic to pump the gossip engine while waiting for other things to make sure gossiped messages get consumed (practically discarded until worker is fully initialized). This fixes an issue where node operators saw error logs, and fixes potential RAM bloat when BEEFY initialization takes a long time (i.e. during clean sync).

[#3477]: Allow parachain which acquires multiple coretime cores to make progress

Adds the needed changes so that parachains which acquire multiple coretime cores can still make progress. Only one of the cores will be able to be occupied at a time. Only works if the ElasticScalingMVP node feature is enabled in the runtime and the block author validator is updated to include this change.

Changelog for Runtime Dev

[#1660]: Implements a percentage cap on staking rewards from era inflation

The pallet-staking exposes a new perbill configuration, MaxStakersRewards, which caps the amount of era inflation that is distributed to the stakers. The remainder of the era inflation is minted directly into T::RewardRemainder account. This allows the runtime to be configured to assign a minimum inflation value per era to a specific account (e.g. treasury).

[#3052]: Fixes a scenario where a nomination pool's TotalValueLocked is out of sync due to staking's implicit withdraw

The nomination pools pallet TotalValueLocked may get out of sync if the staking pallet does implicit withdrawal of unlocking chunks belonging to a bonded pool stash. This fix is based on a new method on the OnStakingUpdate traits, on_withdraw, which allows the nomination pools pallet to adjust the TotalValueLocked every time there is an implicit or explicit withdrawal from a bonded pool's stash.

[#3384]: [pallet_contracts] stabilize call_v2, instantiate_v2, lock_dependency and unlock_dependency

These APIs are currently unstable and are being stabilized in this PR. Note: add_delegate_dependency and remove_delegate_dependency have been renamed to lock_dependency and unlock_dependency respectively.

[#3225]: Introduce submit_finality_proof_ex call to bridges GRANDPA pallet

New call has been added to pallet-bridge-grandpa: submit_finality_proof_ex. It should be used instead of deprecated submit_finality_proof. submit_finality_proof will be removed later.

[#3325]: Ensure TracksInfo tracks are sorted by ID.

Add a integrity_check function to trait TracksInfo and explicitly state that tracks must always be sorted by ID. The referenda pallet now also uses this check in its integrity_test.

[#2903]: Implement ConversionToAssetBalance in asset-rate

Implements the ConversionToAssetBalance trait to the asset-rate pallet.

Previously only the ConversionFromAssetBalance trait was implemented, which would allow to convert an asset balance into the corresponding native balance.

The ConversionToAssetBalance allows to use pallet-asset-rate, e.g., as a mechanism to charge XCM fees in an asset that is not the native.

[#3361]: Fix double charge of host function weight

Fixed a double charge which can lead to quadratic gas consumption of the call and instantiate host functions.

[#3060]: Add retry mechanics to pallet-scheduler

This PR adds retry mechanics to pallet-scheduler, as described in the issue above. Users can now set a retry configuration for a task so that, in case its scheduled run fails, it will be retried after a number of blocks, for a specified number of times or until it succeeds. If a retried task runs successfully before running out of retries, its remaining retry counter will be reset to the initial value. If a retried task runs out of retries, it will be removed from the schedule. Tasks which need to be scheduled for a retry are still subject to weight metering and agenda space, same as a regular task. Periodic tasks will have their periodic schedule put on hold while the task is retrying.

[#3243]: Don't fail fast if the weight limit of a cross contract call is too big

Cross contracts calls will now be executed even if the supplied weight limit is bigger than the reamining weight. If the actual weight is too low they will fail in the cross contract call and roll back. This is different from the old behaviour where the limit for the cross contract call must be smaller than the remaining weight.

[#2061]: Add Parameters Pallet

Adds pallet-parameters that allows to have parameters for pallet configs that dynamically change at runtime. Allows to be permissioned on a per-key basis and is compatible with ORML macros.

[#3154]: Contracts: Stabilize caller_is_root API

Removed the #[unstable] attrribute on caller_is_root host function.

[#3212]: Ranked collective introduce Add and Remove origins

Add two new origins to the ranked-collective pallet. One to add new members and one to remove members, named AddOrigin and RemoveOrigin respectively.

[#3370]: Remove key getter from pallet-sudo

Removed the key getter function from the sudo pallet. There is no replacement for getting the key currently.

[#2290]: im-online pallet offcain storage cleanup

Adds a function clear_offchain_storage to pallet-im-online. This function can be used after the pallet was removed to clear its offchain storage.

[#3184]: Contracts: Remove no longer enforced limits from the Schedule

The limits are no longer in use and do nothing. Every builder overwritting them can just adapt their code to remove them without any consequence.

[#3415]: [pallet-contracts] Add APIVersion to the config.

Add APIVersion to the config to communicate the state of the Host functions exposed by the pallet.

Changelog for Runtime User

[#3319]: Add Coretime to Westend

Add the on demand and coretime assigners and migrate from legacy parachain auctions to coretime.

[#3232]: Validate code when scheduling uprades

Adds checks to ensure that the validation code is valid before scheduling a code upgrade.

[#3272]: Westend Coretime Runtime

Add the Broker pallet to the Westend Coretime Chain runtime for the main functionality and sales to start.

[#2949]: Enable async backing on all testnet system chains

Async backing has been enabled on all testnet system chains: asset-hub-westend, bridge-hub-westend, bridge-hub-rococo, collectives-westend, contracts-rococo, coretime-westend, coretime-rococo, people-westend, and people-rococo. These now target 6s block times. For the running coretime chains, that requires updating the configuration after the runtime upgrade but before the end of the current region.

[#3007]: Try State Hook for Ranked Collective.

Invariants for storage items in the ranked collective pallet. Enforces the following Invariants:

1. Total number of Members in storage should be >= [MemberIndex] of a [Rank] in MemberCount.
2. Rank in Members should be in MemberCount.
3. Sum of MemberCount index should be the same as the sum of all the index attained for rank possessed by Members
4. Member in storage of IdToIndex should be the same as Member in IndexToId.
5. Rank in IdToIndex should be the same as the the Rank in IndexToId.
6. Rank of the member who in IdToIndex should be the same as the Rank of the member who in Members

Changes

Changelog for Node Dev.

#2689 & #3074: Fix BEEFY & Warp Sync compatibility - Allow Warp Sync for Validators

#2942: Fix pallet-nomination-pools v6 to v7 migration

Restores the behaviour of the nomination pools V6ToV7 migration so that it still works when the pallet will be upgraded to V8 afterwards.

#3108: revert paritytech/polkadot#6577 & related changes

Moves BEEFY related pallets behind session_pallet for Rococo and Westend runtimes. Effects that each MmrLeaf in the MMR generated by mmr_pallet for block<N> references the next_auth_set of block<N> and not block<N-1>. Breaking change for proofs generated by mmr_generateProof

#2125: Introduce bounds for the number of candidate validation subsystem simultaneously processed tasks

Makes it possible for the candidate validation subsystem to create backpressure on subsystems requesting to validate a candidate through limiting the number of simultaneously processed validation tasks.

#2970: Add availability-distribution and biftield-distribution subsystem benchmark

The new subsystem benchmark test objective (DataAvailabilityWrite) is designed to stress test the part of the pipeline that takes as input a backed candidate and then distributes it as erasure coded chunks to other validators. The test pulls in the av-store, bitfield-distribution and availability-distribution subsystems while the whole network and rest of the node subsystems are emulated.

#2467: Extract warp sync strategy from ChainSync

WarpSync, and StateSync as the logical part of warp sync, are extracted from ChainSync as independent syncing strategies. SyncingStrategy enum is introduced as a proxy between SyncingEngine and specific strategies. SyncingStrategy may be replaced by a trait in a follow-up PRs.

#3040: Rename transaction to transactionWatch

Renamed transaction_unstable_submitAndWatch to transactionWatch_unstable_submitAndWatch, transaction_unstable_watchEvent to transactionWatch_unstable_watchEvent and transaction_unstable_unwatch to transactionWatch_unstable_unwatch.

#3061: Do not run unneeded subsystems on collator and its alongside node

Optimizes overseer building strategy to only include subsystems needed to run the given type of node. Reduces overseer overhead and also solves the problem with unused subsystems getting stalled from time to time.

Changelog for Node Operator.

#2477: Use clone instead of fork on pvf

For validators: Adds a new, optional security capability. Most modern Linux machines should support it, otherwise you will get a warning like: "- Optional: Cannot call clone with all sandboxing flags, a Linux-specific kernel security features: not available". If you are already running in a secure environment such as a container, this may conflict with our security features; your only option may be to ignore the warning. Otherwise, it is recommended to upgrade your Linux version!

#3009: sc-informant: Respect --disable-log-color

Fixes some places that weren't respecting the --disable-log-color CLI flag.

#1313: backpressured JSON-RPC server (upgrade jsonrpsee)

Modifies the jsonrpc server to be "backpressured" and it's possible to configure how many messages can be "buffered" via the CLI --rpc_message_buffer_capacity.

Major changes in this PR:

• The subscriptions are now bounded and if subscription can't keep up with the server it is dropped
• CLI: add parameter to configure the jsonrpc server bounded message buffer (default is 64)
• Add our own subscription helper to deal with the unbounded streams in substrate

Changelog for Runtime Dev.

#3156: Adapt core-fellowship and salary pallets for swapped members

The ranked-collective pallet got the ability to swap members but the core-fellowship and salary pallets would not be notified of this change. This MR adds MemberSwappedHandler to the collective that is implemented by both pallets.

#1230: XCMv4

A new version of the XCM format. The main changes are:

• Removed Multi prefix from types
• Removed Abstract asset id
• Outcome is now a named fields struct
• Added Reanchorable trait, implemented for both Location and Asset
• New syntax for building Locations and Junctions using slices. You build them like let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]); and match on them like match location.unpack() { (1, [Parachain(id)]) => ... (0, Here) => ..., (1, [_]) => ..., }

#3001: Introduce Balances::force_adjust_total_issuance

Introduce a root extrinsic to forcefully adjust the Total Issuance. Should only be used to fix historic errors.

#1845: XCM WeightTrader: Swap Fee Asset for Native Asset

Implements an XCM executor WeightTrader, facilitating fee payments in any asset that can be exchanged for a native asset.

A few constraints need to be observed:

• buy_weight and refund operations must be atomic, as another weight trader implementation might be attempted in case of failure.
• swap credit must be utilized since there isn’t an account to which an asset of some class can be deposited with a guarantee to meet the existential deposit requirement.

#2924: Add NonFungibleAdapter

Introduces a new adapter, NonFungibleAdapter, to work with frame_support::traits::tokens::nonfungible through XCM.

#3108: revert paritytech/polkadot#6577 & related changes

Moves BEEFY related pallets behind session_pallet for Rococo and Westend runtimes. Effects that each MmrLeaf in the MMR generated by mmr_pallet for block<N> references the next_auth_set of block<N> and not block<N-1>.

#1296: fungible fixes and more conformance tests

Adds conformance tests for the Balanced and Unbalanced fungible traits. Fixes Unbalanced::decrease_balance not respecting preservation. Fixes Balanced::pair possibly returning pairs of imbalances which do not cancel each other out. Method now returns a Result instead (breaking change). Fixes Balances pallet active_issuance possible 'underflow'. Refactors the conformance test file structure to match the fungible file structure: tests for traits in regular.rs go into a test file named regular.rs, tests for traits in freezes.rs go into a test file named freezes.rs, etc. Improve doc comments. Simplify macros.

#3029: Snowbridge Ethereum Deneb fork preparation

Changes the Rococo runtime Ethereum fork config to include the Deneb hard-fork. Updates the Snowbridge subtree with preparation for Deneb. Removes the beacon-minimal-spec feature.

#2657: [frame] #[pallet::composite_enum] improved variant count handling + removed pallet_balances's MaxHolds config

The implementation of the VariantCount trait for aggregate composite enums, such as RuntimeHoldReason and RuntimeFreezeReason, has been fixed. It is now calculated as the sum of VariantCount::VARIANT_COUNT for all corresponding #[pallet::composite_enum]. The Balances pallet's Config item type MaxHolds has been removed, and type Holds is now bound to the variant count of the composite enum RuntimeHoldReason. Consequently, the runtime does not need to consider setting the correct value for MaxHolds.

notes:

• Remove type MaxHolds from the impl pallet_balances::Config for Runtime in the runtime.
• When holds are expected to be used, ensure that type RuntimeHoldReason = RuntimeHoldReason is set for impl pallet_balances::Config for Runtime.

#3110: Nomination pools Fix payout destination in permissionless unbond

This PR fixes an issue whereby when a nomination pool allowed for permissionless unbonding of funds, the implicit claimed rewards were mistakenly sent to the caller of the unbond, and not the actual member. A nomination pool only allows permissionless unbonding when its state was set into Destroying by the operator.

#1222: Transactional processing for XCM

Transactional processing was introduced for certain XCM instructions. They are:

• WithdrawAsset
• ReserveAssetDeposited
• TransferAsset
• TransferReserveAsset
• ReceiveTeleportedAsset
• DepositAsset
• DepositReserveAsset
• InitiateReserveWithdraw
• InitiateTeleport
• BuyExecution
• ClaimAsset
• ExportMessage
• LockAsset
• UnlockAsset
• RequestUnlock

Developers must specify a TransactionalProcessor when configuring their XCM executor. FRAME-based runtimes would simply need to configure it with FrameTransactionalProcessor to enable transactional processing. To disable transactional processing of XCMs, () may also be specified as the type for TransactionalProcessor. For runtimes that are not FRAME-based but would like to still harness transactional processing of XCMs, a type implementing the ProcessTransaction trait must be specified as the type for TransactionalProcessor. This trait is for the purpose of connecting the chain's runtime transactional processor with the XCM executor -- any implementation of ProcessTransaction is possible to be assigned as the TransactionalProcessor for the XCM executor.

#3057: Serialize/Deserialize trait implemented in no-std for XCM assets types

Serialize/Deserialize trait implemented in no-std for XCM v3 and v4 assets types

#2920: Contracts: Stabilize sr25519_verify host function

Removed the #[unstable] attrribute on sr25519_verify host function.

#3228: [pallet_xcm] Forgotten migration to XCMv4 + added try-state to the pallet_xcm

The current release includes the new XCMv4, so the runtimes must incorporate a migration pallet_xcm::migration::MigrateToLatestXcmVersion<Runtime> to ensure proper data migration in pallet_xcm.

Changelog for Runtime User.

#2796: Rococo and Westend Asset-Hub: XCM Transfers with Pallet-Uniques

With the added UniquesTransactor Rococo and Westend Asset-Hub are now capable of handling XCM transfers with pallet-uniques.

#2587: Allow fellowship members to swap their AccountIds.

Add a exchange_member extrinsic to the ranked-collective pallet that allows to vote on swapping the AccountId of a member. This can be used to recover lost access to a collective.

#3020: Para registration deposit covering max code size

With this PR all newly registered parachains must pay a deposit equivalent to the cost of registering validation code of the maximum size. Consequently, they can upgrade their code to the maximum size at any point without additional cost.

#2826: Enable async backing on asset-hub-rococo

Async backing has been enabled on Asset Hub Rococo, which now targets 6s block times.

#2889: Filter backing votes from disabled validators in paras_inherent

paras_inherent drops any backing votes from disabled validators on block import and asserts that no votes from disabled validators are included in a block during execution

#3077: Enable cross-chain Coretime region transfers on Rococo Coretime chain

This PR allows Coretime regions to be cross-chain transferred from the Rococo Coretime chain.

#1871: Adding try-state hook to tips pallet

Enforces the following invariants;

1. The number of entries in Tips should be equal to Reasons.
2. If OpenTip.finders_fee is true, then OpenTip.deposit should be greater than zero.
3. Reasons exists for each Tip[OpenTip.reason], implying equal length of storage.

This release contains the changes from polkadot-v1.5.0 to polkadot-v1.6.0.

Rust compiler versions

This release was built and tested against the following versions of rustc. Other versions may work.

Rust Stable:  rustc 1.74.0 (79e9716c9 2023-11-13)
Rust Nightly: rustc 1.75.0-nightly (9d83ac217 2023-10-31)

This release contains the changes from polkadot-v1.4.0 to polkadot-v1.5.0.

⚠️Note: It's possible to run into a warning similar to this one:

  - Optional: Cannot unshare user namespace and change root, which are Linux-specific kernel security features: could not create a temporary directory in "/tmp/.tmpIcLriO": No such file or directory (os error 2) at path "/tmp/.tmpIcLriO/check-can-unshare-4XnFgA"

Mitigation: This is not harmful. The validator will have to make sure the PVF artifact directory (listed in the error message) exists, and restart the node.

Issue: https://github.com/paritytech/polkadot-sdk/issues/2662

Rust compiler versions

This release was built and tested against the following versions of rustc. Other versions may work.
