This release brings MetaMask and other consensus fixes to Mainnet. After the activation of the feature #18 all Protocol changes become available. This release is mandatory for all nodes: outdated nodes will shut down when new feature is activated, which is expected to happen on February, 18th, given sufficient miners support.
This release includes several consensus improvements implemented as hard forks which are bound to feature #18 "Consensus and MetaMask improvements".

If you use your node to retrieve NFT list and rely on correct NFT order, you need to re-import blockchain for the fix to have effect./utils/script/evaluate shows state changes when transaction-like invocation is evaluated. Also default complexity limit has been increased to 52000 to match invocation complexity limit.waves.utx.always-unlimited-execution. When enabled, all script invocations are evaluated completely, not up to the fail-free limit. This functionality is turned off by default.docker run -it wavesplatform/wavesnode:1.4.13 import -c /etc/waves/waves.conf -i https://blockchain.wavesnodes.com/mainnet_last
To activate the improvements listed above, please vote for feature #18 on Mainnet!
Unless you rely on proper NFT order described above, there's no need to re-import state when upgrading from 1.4.11.

This release improves node performance and prevents miners from generating empty blocks under heavy load. This release is strongly recommended for all node operators, especially miners.
/utils/script/evaluate/{address}This release adds support for evaluating transactions with /utils/script/evaluate/{address} endpoind. Transaction JSON can be specified in the request body. Neither proofs nor attached payments are validated; transaction sender, ID and other fields are retrieved from the supplied JSON. dApp field is ignored, the function is evaluated in the context of {address}. This functionality simplifies debugging contracts: no private key is required to simulate transaction processing.
There's no need to re-import state when updating from 1.4.10.

This is a mandatory release which resolves an issue with transaction validation, as well as improves block processing performace for blocks containing excessive number of transactions.
An issue with docker containers introduced in 1.4.9 has also been fixed. There's no need to explicitly specify waves.directory in custom waves.conf unless you need to store data files in the non-default directory.
There's no need to re-import blockchain when updating from v1.4.9.

This is a mandatory release. Mainnet nodes need to be updated before feature #17 is activated, which will happen at height 3180000 (approx. on Jun 27 2022 05:37 UTC).
This release also includes the following changes:
waves.rest-api.cors-headers.access-control-allow-origin setting, origin-from-request, has been added. When set, the node will send Access-Control-Allow-Origin: response header with the value taken from the Origin: request header. This allows to use a single node instance with multiple origins. See docs for details.1370649165da1d2a6b2f2a8031352195e6661614398ac08d7639285375757902 waves-all-1.4.7.jar

This release is an accumulation of all previous 1.4.x releases. Now it's available for Mainnet. After the activation of the feature #17 all Protocol changes become available.
priceMode parameter of order version 4. The parameter enables price mode similar to order version 3.Issued version 6 of the Ride Standard library.
The maximum complexity of a callable function of a dApp script in Standard library version 6 is changed to 52 000.
The maximum total complexity of all callable functions and asset scripts within a transaction depends on the version of Standard library in the first dApp script invoked:
The sender's account script complexity is not included in that limit.
New complexity estimation rules reduce overall script complexity.
The maximum size of a dApp script is increased to 160 Kbytes regardless of the Standard library version.
The maximum total number of ScriptTransfer, Lease, LeaseCancel script actions executed by all callable functions in a single transaction is 100.
The maximum total number of Issue, Reissue, Burn, SponsorFee script actions executed by all callable functions in a single transaction is 30.
Callable functions no longer accept arguments of type Union.
Added the following built-in functions:
Changed the limitation on the second parameter of drop, dropRight, take, takeRight string functions and byte array functions.
Changed the limitations on input and output data size for the built-in string functions makeString and split; their complexity reduced to 1. Added the range of similar functions with different complexity depending on the data size.
Changed the complexity of certain built-in functions. The complexity is given in the [Ride v6] Built-in functions article.
Introduced a limit on the total number of payments attached to dApp script invocations in a single transaction: a maximum of 100. The limit does not depend on the Standard library versions used.
Added support for Ethereum transactions that perform token transfers or dApp script invocations. JSON representation of a transaction depends on its content:

Features of the Ethereum transaction JSON representation:
sender contains Waves address base58 encoded,senderPublicKey is 64 bytes base58 encoded,bytes contains the entire Ethereum transaction bytes, including the ECDSA signature, HEX encoded.proofs array is missing.Added support for Exchange transactions containing an order (or both orders) with an ECDSA signature.
