The Parity Polkadot Blockchain SDK

polkadot-v1.5.0

6 months ago

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

v1.4.0

6 months ago

This release contains the changes from v1.3.0 to v1.4.0.

⚠️Note: There is a known bug which leads to the following error messages in logs:

Nov 21 13:37:34.593 ERROR parachain::pvf: 🚨 Your system cannot securely run a validator. 
Running validation of malicious PVF code has a higher risk of compromising this machine.
  - Cannot unshare user namespace and change root, which are Linux-specific kernel security features: not available: Nov 21 13:37:34.582 TRACE parachain::pvf-common: unsharing the user namespace and calling pivot_root worker_kind=check pivot root worker_pid=1562989 worker_dir_path="/tmp/.tmpxnRzK7/check-can-unshare4LXkykVpKt"

Nov 21 13:37:34.594 ERROR parachain::pvf: In the next release this will be a hard error by default.
     
More information: https://wiki.polkadot.network/docs/maintain-guides-secure-validator#secure-validator-mode

This error will be fixed with the next release and can be ignored for now. NOTE: after this release, this error should be treated as legitimate!

polkadot-v1.1.0

9 months ago

This release contains the changes from v1.0.0 to v1.1.0.

Monorepo

The 3 repositories substrate, polkadot and cumulus have now been merged as a single monorepo: polkadot-sdk.

You can find more details about this here.

The previous versions can be found at:

Rust compiler versions

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

Rust Stable: rustc 1.70.0 (90c541806 2023-05-31)
Rust Nightly: rustc 1.71.0-nightly (8b4b20836 2023-05-22)

Special notes

BEEFY on Kusama

BEEFY has been enabled on Westend and Kusama, although at the moment does not also support warp sync. Attempting to Warp sync as a validator on Kusama (and Westend) will throw an error. If experiencing stability issues caused by BEEFY, it can be disabled using --no-beefy flag. This change does not affect Polkadot, as BEEFY is not yet enabled for Polkadot.

`Staking-miner`

The staking-miner has been removed from this release. The new staking-miner can be found in the staking-miner-v2 repository.

Removal of the Polkadot native features

If you want to run your node with polkadot-dev as chain, you will need to compile your node with --features polkadot-native. In the future the support for polkadot-dev or kusama-dev will be removed completely.

`polkadot` binary split

The polkadot binary is being split up into multiple binaries instead of a single polkadot binary.

More details are described in this PR. There are additional polkadot-prepare-worker and polkadot-execute-worker binaries placed in the same directory as the main polkadot binary. Nothing regarding CLI flags or the way the polkadot binary gets run changes, these executables are just separated out and need to be accessible and on the same versions as the main polkadot binary.

This likely requires people to update their automation like ansible scripting. The provided docker images already contain all the required binaries.

New Docker base image

The Docker image for Polkadot is now based on ubuntu:22.04. It was ubuntu:20.04 until now. The default user also changed from polkadot (home in /polkadot) to parity (home in /parity).
