-## v0.8.2 (2026-06-08)
+## v0.9.0 (2026-06-23)
 
-### User-facing changes
+A large feature release: a full activity/audit log, two roadmap batches of
+capture and smart-light improvements, per-pixel control for LIFX/Hue/Nanoleaf,
+and new outbound integrations (webhooks + Home Assistant MQTT discovery).
 
-#### Features
+### Features

+- `auth.expose_docs` flag (default off) to view `/docs`, `/redoc`, and
+  `/openapi.json` without a token; all real endpoints stay protected ([126d8f2](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/126d8f2))
 
-##### Region-of-interest (ROI) screen capture
-- Screen sampling can now be cropped to a **region of interest** instead of the whole display ([ca59546](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/ca59546))
-
-##### Built-in "look" presets

-- Removed a broken legacy `/system/mqtt/settings` route ([fdc9201](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/fdc9201))
-- Scene brightness value-source changes now sync to the live processor immediately ([02e2ea3](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/02e2ea3))
-- Wizard hardening: scaffolded targets are registered with the ProcessorManager and the final review step is more robust ([6cd5e05](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/6cd5e05))
-- Installer opens the WebUI only once after "Launch LedGrab" ([05cf121](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/05cf121))

+  (amd64 path untouched) ([6745e25](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/6745e25))
 
-#### Frontend
-- In-progress dashboard customization groundwork ([6180569](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/6180569))
+#### Chores
+- Activity Log feature plan/subplan scaffold, post-merge cleanup, and context
+  graduated into CLAUDE.md ([1afe7d6](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/1afe7d6), [e584235](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/e584235))
 
-#### Docs

-
-#### Tests
-- Large new suites for calibration solver/session (incl. adversarial), setup & scene-playlist routes, playlist engine, and ROI capture. Full suite: **2149 passing, 2 skipped**
+> Tests: ~180 new unit tests added across the activity log, roadmap features,
+> and integrations. Release gate green: ruff + tsc + build clean,
+> **pytest 2739 passed / 2 skipped**.
