type: entityconfidence: highupdated: 2026-04-13hermes_version: v0.9.0sources: 1

Overview

The "everywhere release" (2026-04-13). Hermes crosses the threshold from a CLI-first tool to a multi-surface platform: browser dashboard, mobile (Termux/Android), iMessage, WeChat. Plus Fast Mode for priority model routing, pluggable context engines, and a security hardening pass. 5-day turnaround from v0.8.0 at an unusually high pace (269 PRs).

How to Use

Upgrading from v0.8.0

hermes update

Expected to be non-breaking for most users. Notable behavior changes:

  • Credential exhaustion TTL reduced from 24h to 1h — if you have credential pools, rate-limited keys recover ~24x faster.
  • Config.yaml now takes priority over env vars for auxiliary settings (inverted from v0.8.0 on edge cases).
  • Matrix users migrate automatically from matrix-nio to mautrix-python — watch for transient E2EE re-trust prompts.

Opt-in new features

  • Web Dashboard: hermes dashboard or access at http://localhost:<port> (check docs for port)
  • Fast Mode: toggle with /fast in chat (OpenAI Priority Processing + Anthropic fast tier)
  • Background watch patterns: pass watch_patterns=["PANIC", "listening on"] to background terminal(...) or process(...) calls
  • Backup your setup: hermes backup → tar.gz you can carry to another machine
  • Debug share: hermes debug share → pastebin URL with sanitized report for troubleshooting

New platform setup

  • iMessage (BlueBubbles): install BlueBubbles server on a Mac, configure in hermes setup → Messaging
  • WeChat (Weixin): requires iLink Bot API credentials; setup wizard
  • WeCom Callback: for self-built enterprise apps; configure via setup wizard
