Hey folks! The Banff 9 Update (v.1.9.9) has just been released!

Main focuses of this release are the removal of the go-plugin, C-Chain State Sync Default*, and the enablement of the EVM JS TracerDisclaimer on C-Chain State Sync:
If you are not interested in state sync, you will need to make sure you specify state-sync-enabled:false. Nodes should not start state syncing if it has the contents of the previous block but are something to be aware of. This version is backwards to v.1.9.0. The update is optional but encouragwed.

Here is a copy of the full release notes: This version is backwards compatible to v1.9.0. It is optional but encouraged. The supported plugin version is 23.
Note: The --whitelisted-subnets flag was deprecated in v1.9.6. This is the last release in which it will be supported. Use --track-subnets instead.
