-## 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)
