Each version starts with a heading like 'ClickHouse release 26.3 LTS' followed by a date. Group all content under a version heading (Backward Incompatible Changes, New Features, Bug Fixes, etc.) into ONE release per version. Do NOT create separate releases for individual changelog items.\n\n## Agent Notes\n\n### Extraction patterns\n\n**ClickHouse GitHub (`clickhouse`)** — GitHub Releases source tracking patch-level versions (e.g., v26.3.7.8-lts, v26.2.11.5-stable). ClickHouse maintains multiple concurrent release branches (LTS + stable), so expect several releases per day during active patch cycles. Version format: `v{major}.{minor}.{patch}.{build}-{track}` where track is `lts`, `stable`, or `testing`. High volume — 100 releases fetched in initial load, ~22 in the last 30 days.\n\n**ClickHouse Blog (`clickhouse-blog`)** — RSS feed at `clickhouse.com/rss.xml`. This is a **site-wide** RSS feed covering all blog content, not just release announcements. Most entries are articles, tutorials, and case studies (no version numbers). Occasional release announcement posts (e.g., \"ClickHouse Release 26.3\") appear alongside editorial content. Useful as a supplementary signal for major releases but noisy.\n\n**ClickHouse Changelog (`clickhouse-changelog`)** — The canonical version changelog at `clickhouse.com/docs/whats-new/changelog`. Docusaurus-powered, single-page per year. Each page contains multiple version releases with sections: Backward Incompatible Changes, New Features, Experimental Features, Performance Improvements, Improvements, Bug Fixes, Build/Testing/Packaging. Very large pages (~300K chars for a single year). Feed discovery is **disabled** (`noFeedFound: true`) because the site-wide RSS returns blog posts, not changelog entries. The parseInstructions tell the AI to group content by version heading rather than splitting individual items.\n\n### Known quirks\n\n- The site-wide RSS (`clickhouse.com/rss.xml`) is shared between the blog source and the docs changelog — feed discovery must be disabled on the changelog source to prevent it from pulling blog posts instead\n- Changelog pages are very large (300K+ chars) and get chunked into 20+ parsing segments — expect fetches to take 2-3 minutes and consume significant AI tokens\n- The GitHub source produces high-frequency patch releases across multiple branches simultaneously — don't be alarmed by 5+ releases in a single day\n- The changelog page URL rotates yearly: current year is at `/docs/whats-new/changelog`, prior years at `/docs/whats-new/changelog/{year}` (2017–2025 available). To backfill older releases, the source URL would need to be temporarily changed or additional sources added per year\n\n### Source coverage\n\nThe three sources provide complementary coverage:\n- **GitHub releases**: Patch-level detail for every tagged release across all branches (highest granularity, highest volume)\n- **Docs changelog**: Major version release notes with categorized changes — the canonical reference (marked as primary)\n- **Blog**: Supplementary; captures major release announcements and context articles\n\n**Yearly archives**: Historical changelogs are available at `clickhouse.com/docs/category/changelog` which indexes years 2017–2026. Each year links to `/docs/whats-new/changelog/{year}`. The current changelog source only tracks the current year's page. To backfill older data, add temporary scrape sources for specific years (same parseInstructions apply) or update the source URL.\n\n**Gap**: No dedicated feed exists for the docs changelog section — this is a Docusaurus limitation. The blog RSS is the only structured feed available, and it covers all blog content, not just releases.\n","updatedAt":"2026-04-18T20:42:37.607Z"}}
