…ompatible tags - Update Dockerfile.v2 to use Debian trixie as base OS - Update library packages for trixie (including t64 time64 transition libs) - Support both trixie and bookworm BASEOS values for smooth transition - Update docker-ci.yml and docker-image.v2.yml matrices to build v2 on trixie - v1 images remain on bookworm (no change) - Add automatic bookworm tag aliasing for v2 trixie-built images - Also add bullseye compatibility tags for maximum backward compatibility This provides users pulling :bookworm tags with the latest trixie-built images while maintaining tag continuity. The same digest is served for both :trixie and :bookworm tags on v2 images.
- Update README with Trixie migration notice and base OS clarification - Add detailed migration guide section in docs/migration.md - Create CHANGELOG.md with unreleased Trixie migration entry - Document tag mapping (trixie/bookworm/bullseye compatibility) - Add library version comparison table (t64 time64 updates) - Include testing checklist, rollback plan, and FAQ - Clarify v1 vs v2 base OS differences
Remove the static CHANGELOG.md to avoid duplication; rely on git history, release notes, and existing docs for change tracking.
