This release updates the Flare and Songbird codebase to AvalancheGo v1.14.2.
The upgrade is optional but encouraged. It is backwards compatible with v1.14.0 and does not schedule any new fork times.
Note:
- Coreth and Subnet-EVM are now grafted into the AvalancheGo tree — there is no separate coreth module anymore. Go import paths change from github.com/ava-labs/coreth/... to github.com/ava-labs/avalanchego/graft/coreth/..., which affects downstream tools that import Coreth packages.
- Building from source now requires Go 1.25.11 or later.
