Release History
Every release, every improvement. Full version history sourced from the Hermes Agent GitHub.
Patch release. This tag rolls up the 338 PRs merged since v0.21.2 into a stable tagged release for downstream consumers (Docker images, Hermes Cloud, hosted deployments). It exists so the remote-gateway sign-in fixes below reach Cloud agents, which auto-update to the newest release tag.
- Remote dashboard sessions no longer expire on refresh bursts (#110061, fixes #55712; salvage #71548 @Doud-FR, #55717 @liuhao1024). Both refresh paths on the gateway (cookie gate and the desktop's native bearer route) now coalesce concurrent requests carrying the same rotating refresh token, so a Desktop wake burst can no longer replay an already-rotated token into the Portal's reuse detection and revoke the whole session. Refresh also runs off the event loop, so a slow identity provider no longer freezes…
- Long-lived processes stop leaking duplicate state.db writer handles (#110934, fixes #100896 #103339; salvage #107974 @kshitijk4poor, mapping @Rroven): gateway, dashboard/Desktop backend, ACP and CLI readers attach read-only and in-process writers share the registry handle, so the N live SessionDB handles precursor stops firing on a healthy topology.
- Docker / Hermes Cloud: images build from this tag (nousresearch/hermes-agent:v2026.9.14).
