Download Hermes Agent 0.6.2

Release v0.6.2
Release date: June 18, 2026
A feature-packed release with chat UX improvements, security hardening, new slash commands, and contributions from 9 community members.

✨ New Features
Slash Commands
Added slash command support in chat — type / to invoke commands directly from the input bar.
Profile Switcher
Switch between multiple Hermes profiles without restarting the app.
Hermes X Follow
Integration with Hermes X for the follow feature.
Chat Message Copy Button
A copy icon now appears on hover over each message bubble. Clicking it copies the full message content to clipboard with a brief "Copied!" confirmation. (contributed by @hankkyy)
Collapsible Code Blocks
Code blocks longer than 15 lines or 800 characters are now collapsible with "Show more" / "Show less" toggle. A DOMParser-based HTML pretty-printer also formats inspected elements inside chat. (contributed by @Nameless-Monster-Nerd)
Hebrew (he) Translation with RTL Support
Hebrew is now a fully supported interface language with all 23 namespaces translated. RTL layout is automatically applied when Hebrew is selected. (contributed by @yosef-chai)

🐛 Bug Fixes
Model picker no longer overwrites the global default
Selecting a model from the chat picker previously wrote to config.yaml, permanently changing the global default. The fix separates session-scoped model selection from persistent settings — the chat picker now only overrides the model for that conversation. (contributed by @365diascollaboration-prog, #688)
- Dedicated sessionModelOverride state — only set on explicit in-chat model change, not on config load
- modelOverride threaded through the full send pipeline — from useChatActions → IPC → sendMessageViaBestApi* → gateway/CLI fallback
- TUI gateway bypass guard — the gateway is skipped when a session model is active, since it has no per-request override mechanism
- reload() race condition fixed — loadSeqRef is now incremented on the non-persist path so concurrent reloads can't overwrite an in-session model choice
SSH tunnel chat fallback
In SSH Tunnel mode the dashboard chat WebSocket (/api/ws) was unreachable because the gateway never serves it. A sticky "dashboard unavailable" flag now triggers immediate fallback to the working legacy HTTP transport, with a one-time toast explaining the limitation. The flag resets on any connection change. (#667)
Context-length override leak
The model.context_length override was leaking onto any model when model.default was absent. Now it only applies on an exact match against model.default. Includes a regression test.
/btw attachment drop
Background /btw side-questions carrying attachments silently dropped them. Now falls back to the blocking quick-ask path which properly shows and sends attachments.
Webview security hardening
Fixed web preview security issues and auto-navigation edge cases. (contributed by @Nameless-Monster-Nerd)
macOS click-blocking drag region
Pushed .content top padding by 28px on macOS to clear the fixed window drag region.

🎨 UI Improvements
- Chat Avatar — updated avatar rendering in chat
- Message Row Update — refreshed message row layout
- Updated UI — general UI polish pass
- Text selection visibility — bumped --selection CSS opacity so highlight is clearly visible on dark backgrounds; user bubbles get a bright sky-blue override (contributed by @hankkyy)

⚡ Performance
- SQLite connection caching — cache database connections and improve robustness of SSH/process termination (contributed by @saxster)
- Unit tests for database connection caching added (contributed by @saxster)

🌐 Internationalization
- Hebrew (he) — complete translation with RTL support (contributed by @yosef-chai)
