Changelog
Hermes Agent v0.19.0
The "Quicksilver" release — first-turn time-to-first-token drops roughly 80% across every platform, plus password-manager secrets and smart approvals on by default.
Breaking changes
Read this before upgrading. These are the changes that can stop a working setup.
- Smart approvals are now on by default. Automation that previously ran unattended may start waiting for a confirmation it never used to need — review your approval settings before assuming the agent has hung.
Added
- Live reasoning streams, so you can watch the agent think instead of staring at a blank prompt.
- Secrets can be pulled from Bitwarden and 1Password instead of sitting in plaintext env files.
- Subscription management from the terminal.
- Durable response delivery — replies survive a transient gateway disconnect rather than vanishing.
Fixed
- Substantial desktop and TUI responsiveness work across the board.
Before you upgrade
Snapshot the server first — Hermes ships often and not every release is quiet. Then:
hermes update
Re-run hermes doctor afterwards. If the upgrade leaves you with a
broken install, the fixes section covers the failures
that come up most.
