# Digital Asset Releases Canton 2.10.6 to Improve Post-Migration Reconnects

[Digital Asset has released Canton 2.10.6](https://github.com/digital-asset/canton/releases/tag/v2.10.6), a maintenance update focused on reconnecting after a hard domain migration.

The release is narrowly focused. It addresses performance limitations during hard domain migrations for Canton participants that use a PostgreSQL database and hold a large Active Contract Set — the set of contracts that remain active for a participant. When such a participant reconnects, it must process changes to that set. Digital Asset says version 2.10.6 introduces a faster query path for that reconnect step, replaying ACS changes more efficiently.

### A focused operational improvement

In plain terms, the update is designed to make a specific reconnect step more efficient for a defined type of deployment. The release notes scope the performance change to PostgreSQL-based participants with a large Active Contract Set during hard domain migrations.

The upgrade has operational requirements. It requires a database migration, and the release introduces a new database index and a configuration option for the faster query path. Those are upgrade requirements for operators using the affected configuration.

### Security maintenance, too

The release also upgrades gRPC to version 1.81.0 and the AWS SDK to version 2.49.4. Digital Asset says those dependency updates resolve Netty security issues.

Canton 2.10.6 supports protocol versions 5 and 7. For teams running the affected PostgreSQL configuration, the update targets initial reconnection following a hard domain migration.

It is a targeted maintenance update designed to improve operations for a defined deployment profile.
