Polkadot v0.9.25

on GitHub

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

Database Migrations

Database migrations are operations upgrading the database to the latest stand.
Some migrations may break compatibility, making a backup of your database is highly recommended.

ℹ️ There is no database migration in this release.
