-- Redesign settings/common with Aurora cassettes — refreshed identity, logging, Telegram, and cache-ledger sections with the new glass/cassette UI ([6229bf9](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/6229bf9))
-- Group targets by bot in the targets view and redesign backup settings ([a666bad](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/a666bad))
-- Add `/status` command handler for webhook providers ([bede928](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/bede928))
+### Features
 
-## Bug Fixes
+- **Quiet hours now defer notifications instead of dropping them.** Events that arrive during a tracker's quiet window are stored on disk and re-fired at the window end. Asset events for the same `(link, event_type, collection)` coalesce so a flurry of adds/removes during the night collapses into a single morning notification ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Upstream release check.** New "Release Cassette" in Settings polls a configurable Gitea or GitHub repo on a schedule and surfaces the latest tag in the UI so you know when a newer Notify Bridge is available. Pre-release filtering and interval are operator-configurable; the install ships pointed at this repo's own upstream ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Frontend polish across the board.** New `MetaStrip` component, expanded `EventDetailModal`, and i18n additions land alongside cohesive Aurora-glass styling tweaks on most management pages — providers, targets, bots, trackers, command and notification templates, users, actions, layout, and dashboard ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
 
-- Stop event-log flicker on pagination ([87cb33c](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/87cb33c))
+### Documentation
+
+- README rewritten to cover every supported provider, target type, bot command, and smart action — including the deploy / env-var matrix ([bb5afcc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/bb5afcc), [4335036](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/4335036))
+
+---
+
+## Development / Internal
+
+### Architecture
+
+- New `deferred_dispatch` table with two migrations: an `ON DELETE SET NULL` FK rebuild on `event_log_id` (so the daily event-log retention sweep no longer deadlocks against pending defers), and a partial unique index on `(link_id, collection_id, event_type) WHERE status='pending'` to make coalescing race-safe under SQLite's serializable writes ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- Drain scheduler with three layers: a one-shot APScheduler `date` job per window-end (idempotent, minute-bucketed), a 5-minute periodic catch-up scan as safety net for misfire-grace overflow and process-restart gaps, and `load_pending_drain_jobs` to re-arm scheduled drains on boot ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- Release-check provider abstraction (`packages/core/.../release/`) with Gitea and GitHub adapters, SSRF-safe outbound URL validation, a registry/factory, and a server-side scheduler probe with cached state and on-settings-change cache invalidation ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- Version resolution helper (`packages/server/.../version.py`) that returns the max of installed-package metadata vs source `pyproject.toml` — fixes the long-running editable-install bug where bumping the version without reinstalling kept the old number visible in the UI ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+
+### Tests
+
+- New test suites: `test_deferred_dispatch.py` (drain + coalescing + retention interaction), `test_release_provider.py` (Gitea and GitHub adapter parsing and error paths), and `test_release_service.py` (scheduler-level caching and settings invalidation) ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
