v1.21.1

Release notes

This hotfix release is a recommended update for all network operators and addresses the invalid block production issue initially reported on the Gnosis chain from October 19 to 20.

⚠️ IMPORTANT

Since v1.21.0, the Nethermind executable has been renamed from Nethermind.Runner to nethermind
The Docker images entry points have been updated accordingly.
Please update your setups accordingly, if any.

The obsolete --config xdai option has been deprecated in favor of --config gnosis.
Also, to avoid syncing from scratch, rename the "xdai" directory to "gnosis" in the Nethermind database directory (by default, "nethermind_db").
