+## [v0.32] Auto-Compaction Handling + /compact Command (Issue #90)
+*April 5, 2026 | 424 tests*
+
+### Features
+- **Auto-compaction detection.** When the agent's `run_conversation()` triggers
+  context compression and rotates the session ID, the WebUI detects the mismatch
+  and renames the session file + cache entry so messages don't split across files.
+- **`compressed` SSE event.** Frontend receives a notification when compression
+  fires, shows a system message ("Context was auto-compressed") and a toast.
+- **`/compact` slash command.** Type `/compact` to request the agent compress
+  the conversation context. Sends a natural-language message that triggers the
+  agent's compression preflight.
+- **Real context window data.** The context usage indicator now uses actual
+  `context_length`, `threshold_tokens`, and `last_prompt_tokens` from the agent's
+  compressor instead of the client-side model name lookup. Tooltip shows the
+  auto-compress threshold. Hides gracefully when the agent has no compressor.
+
+### Architecture
+- `api/streaming.py`: Session ID mismatch detection after `run_conversation()`,
+  file rename, SESSIONS cache update under lock, `compressed` SSE event,
+  `context_length`/`threshold_tokens`/`last_prompt_tokens` in usage dict.
+- `static/commands.js`: `/compact` command.
+- `static/messages.js`: `compressed` SSE event handler.
+- `static/ui.js`: `_syncCtxIndicator()` rewritten to use server-side compressor
+  data instead of client-side model estimates.
+

+
+## [v0.31.2] CLI session delete fix
+*April 5, 2026 | 424 tests*
+
+### Bug Fixes
+- **CLI sessions could not be deleted from the sidebar.** The delete handler only
+  removed the WebUI JSON session file, so CLI-backed sessions came back on refresh.
+  Added `delete_cli_session(sid)` in `api/models.py` and call it from
+  `/api/session/delete` so the SQLite `state.db` row and messages are removed too.
+  (#87, #88)
+
+### Notes
+- The public test suite still passes at 424/424.
+- Issue #87 already had a comment confirming the root cause, so no new issue comment
+  was needed here.
+
+## [v0.31] UI Polish + Deployment Hardening
+*April 4, 2026 | 424 tests*
+
+### Bug Fixes
+- **Profile dropdown overlaps chat messages.** `.topbar` had no stacking context,
+  causing the dropdown to paint over `.messages`. Added `position:relative;z-index:10`
+  to `.topbar`. (#71)
+- **Workspace dropdown clipped by sidebar.** `.sidebar overflow:hidden` swallowed
+  the upward-opening workspace dropdown entirely. Changed to `overflow:visible`
+  (scroll lives on `.session-list`); added `position:relative;z-index:10` to
+  `.sidebar-bottom`. (#71)
+- **Slash-command autocomplete behind tool cards.** `.composer-wrap` had
+  `position:relative` but no `z-index`, letting tool cards bleed over it.
+  Added `z-index:10`. (#71)
+- **Skill picker clipped inside Settings modal.** `.settings-panel overflow-y:auto`
+  clipped the absolute-positioned skill picker. Moved scroll to `.settings-body`,
+  set panel to `overflow:visible`, raised skill picker to `z-index:1100`. (#71)
+- **CLI session badge blocks action buttons on hover.** Added
+  `.session-item.cli-session:hover::after { display:none }` so the gold "cli"
+  label hides on hover, making archive/delete/pin fully reachable. (#71)
+- **Workspace dropdown name and path crowded on same line.** `.ws-opt` was a plain
+  block with inline spans. Added `flex-direction:column;gap:4px` so name and path
+  stack cleanly. (#71)
+- **Both servers sharing same state directory.** `api/config.py` and `start.sh`
+  both defaulted to `~/.hermes/webui-mvp` (an internal dev name). Changed default
+  to `~/.hermes/webui` -- generic, appropriate for any deployment. Override with
+  `HERMES_WEBUI_STATE_DIR`. (#72, #73)
