# NousResearch/hermes-agent · Telegram topic schema v2→v3 migration fix

## Open now

- Nothing open on GitHub.

A bug where upgrading to 0.21.0 left existing installs without the v2→v3 Telegram topic schema migration, silently breaking auto topic-rename. The accompanying fixes add self-healing migration logic triggered on read paths.
