Polkadot v0.9.25

This release contains the changes from v0.9.24 to v0.9.25.

⚠️ Notes

This release requires a database migration on the parachains db. While this is handled automatically for the rocksdb users, it is not automatic for paritydb.

Therefore users of paritydb are required to prune the parachains database manually before upgrading.

Note: Only delete the _parachains_ db and only if you are running your node on paritydb!
If you are not sure, try upgrading and only delete the parachains folder if your node is not running properly and you get an error like this:

Error:
 InvalidConfiguration("Column config mismatch for column 4. Expected
 "preimage: false, uniform: false, refc: false, compression: 0, ordered: true", 
 got "preimage: false, uniform: false, refc: false, compression: 0, ordered: false")

Nodes run by default on rocksdb, so if you have not tweaked your configuration you should not be affected and should therefore not delete anything.

ParityDB users should delete the following folder (assuming using the default --base-path) before starting the new version:

  • Linux: $HOME/.local/share/polkadot/chains/polkadot/paritydb/parachains
  • MacOS $HOME/Library/Application Support/polkadot/chains/polkadot/paritydb/parachains

Upgrade Priority

❗️ Medium: This is a medium priority release and you should upgrade in a timely manner.

The changes motivating this priority level are:

  • [S] ⏳ pending non-critical audit #11490 ❗️ Medium - Safe and sane multi-item storage removal
    (RUNTIME)

  • [S] ✅ trivial #11590 ❗️ Medium - Remove #[pallet::without_storage_info] for pallet-remark

  • [S] ✅ trivial #11591 ❗️ Medium - Remove without_storage_info for membership pallet

  • [S] ✅ trivial #11584 ❗️ Medium - Implement maxencodedlen on pallet-beefy

  • [S] ⏳ pending non-critical audit #11490 ❗️ Medium - Safe and sane multi-item storage removal

Host functions

The runtimes in this release contain one new host function (not active yet)

Polkadot v0.9.22

This release contains the changes from v0.9.21 to v0.9.22.

Notes

RPC Server

This release switches to a new JSON-RPC server library, which imposes the following changes:

  • IPC transport support has been removed.
  • DEPRECATED CLI --ipc-path: has been been deprecated and does nothing.
  • The maximum number of subscriptions per connection has been hardcoded to 1024, this will be configurable in the next release via a CLI flag.
  • The logging has slightly changed: If you rely on waiting for the output Listening for new connections <ADDR>, it has changed to Running JSON-RPC WS server: addr=<ADDR> to determine when RPC servers has been started.

Weights

As with every release, the weights have been adjusted according to the latest benchmarks.
The details can be found here.

Polkadot v0.9.21

Upgrade Priority

This is a High priority release for Kusama and Polkadot, please update nodes as soon as possible.

Once enough Kusama validators have upgraded to this release, parachain block times for Kusama should significantly decrease.

Rust compiler versions

This release was compiled with following versions of rustc. Other versions may work.

  • Rust Stable: rustc 1.60.0 (7737e0b5c 2022-04-04)
  • Rust Nightly: rustc 1.62.0-nightly (e745b4ddb 2022-04-07)

Runtimes

This is a client only release - there will be no corresponding 9210 runtime upgrade for Polkadot or Kusama

Changes

The only notable change is #5471 - Improve dispute-coordinator message burstiness handling:

  • Based on these changes on testnets, this change should decrease Parachain block times on Kusama to a significant degree.
  • Previously, the dispute-coordinator was the parachain subsystem that took up a large amount of resources, causing generation of offchain information about parachain progress for the runtime to time out (the inherent data was empty and thus, no progress on enacting/backing of parachains from the runtime side could happen). This manifested in longer parachain block times. The fix to this problem is that certain internal queries of the dispute coordinator are now prioritized.
  • Some more context can be found In this issue
