Nous Research released Hermes Agent version v0.21.2, tagged v2026.9.11, on September 11, 2026. This patch release closes a class of state.db fragility bugs. It rolls up everything that landed on main in the four days since v0.21.1. Measured at commit 04dd80a977f40b05e5b2054111747af07a61886a, the window since v0.21.1 contains 947 non merge commits. There are 1,869 changed files (+182,504 / −15,564) and 312 merged PRs. 140 contributors appear in commits, co author trailers, or salvage credits. The release's state.db reliability campaign consists of six PRs that address state.db reliability. Changes include moving hosted rooms to a shared state.db and opening the dashboard read only first. The update routes the cron lifecycle guard through the tracked connection registry. It classifies FTS damage as fts index instead of whole file corruption.
