+## Beta 2 (v0.2.0)
+- Web UI overhaul: fixed header, single-scroll layout, auto pin-to-bottom, infinite scroll history
+- Channel selector moved into menubar brand; commit hash shown subtly
+- SSE realtime updates and JSON APIs for info, channels, tail, history, stream
+- Link cards: robust OG/Twitter parsing, X (Twitter) oEmbed embeds, YouTube oEmbed, direct image previews
+- On-demand link summaries with caching; inline actions (🌚/🌝, ▾) and collapse/expand
+- Dedicated link-only LLM prompt; improved fetch headers; readability extraction; image-to-vision support
+- Mention detection/rate limiting/quiet hours retained and refined
+- Store: case-insensitive channel queries, msgid de-dup, WAL, history paging
+- Metrics: messages ingested, notifications sent, pruned, connection gauge
+- Docker: multi-arch build, healthcheck; version/commit/build injected
+- Numerous bug fixes (template rendering, static assets path, scroll duplicates, initial bottom snap)

 ## Beta 1 (initial release)
 - soju-specific raw connector with event playback and CHATHISTORY fallback

 - AI digest generation: concise natural summaries (no rigid sections); integrates pasted multi-line posts and referenced link context; image links sent to GPT‑5 as vision inputs

-- HTTP endpoints: health, tail, metrics, on-demand digests
+- Web UI with:
+  - Realtime chat tail via SSE; auto-scroll to bottom; preload older history with infinite scroll-up
+  - Link cards with OG/Twitter metadata (X posts via oEmbed), YouTube oEmbed embeds, direct image previews
+  - Inline on-demand link summarization with caching (24h), and a single summarize toggle (🌚/🌝)

 4) Messages and mentions:
    - Each `PRIVMSG` is stored with server-time when available
    - Mentions trigger Pushover notifications subject to quiet hours, urgency, and rate limits
-   - Debug logs include: mention delivered or suppression reason (backfill, quiet hours, rate limit)
 
 5) Summarization:
-   - `/trigger` or the scheduler loads a window and calls OpenAI
-   - GPT‑5 context: ~272k input tokens + up to 128k output tokens (400k total)
-   - Summaries are concise/natural and integrate multi-line posts, article text (readability-extracted), and image links (vision)
