Hermes Agent v0.23.1

Release Date: November 9, 2026

Patch release. This tag rolls up the ~618 PRs merged since v0.23.0 into a stable release for the GitHub release (CLI and installers), the Microsoft Store app, Docker and Hermes Cloud. Full curated notes for this window ship with v0.24.0.

What this patch ships for plugin users: since the plugin catalog's site deploy on November 9, the published plugin-catalog.json was larger than the 2 MiB cap clients accept, so every install silently fell back to the catalog it shipped with. hermes plugins install <name> could not find plugins added since your last update, installed the pin your release shipped instead of the current one, and missed newer removed entries. This release raises the cap to 16 MiB, so the live catalog is used again (#151860, fixes #151856, thanks @100yenadmin). Installs that stay on v0.23.0 or older keep falling back until they update.

About this release

Also in the window, undocumented here on purpose: Esc backtrack in the TUI and classic CLI (replacing the rewind list picker), group chats that run on a gateway without Desktop and can seat bots from other computers, saved gateway connections shared by Desktop and the Webapp, signing the in-app browser in with your real browser profile and filling saved logins from its address bar, hermes gateway attach for local clients, hermes clipboard image --json, new plugin API (session-scoped environment values, plugin JSON-RPC methods and events, llm.oneshot auxiliary tasks, a compression-stable conversation_id, an on_session_open hook in the gateway, a post_curator_run hook), faster transcript and handoff reads, and a large batch of new plugin-catalog entries.

Full curated release notes for this window ship with v0.24.0, which will document everything from v0.23.0 onward — highlights, feature areas, and complete contributor credits. Nothing in this window is skipped.
