Tier renamed: full → chromium — Docker tags change from -full to -chromium (e.g., 8.4-bookworm-chromium). The "full" name implied other tiers were incomplete; "chromium" is honest about what the extra 450MB adds.
Slim tier resized — mongodb, soap, ldap, xsl, grpc, calendar, gettext, and System V IPC extensions moved from slim to standard. Slim is now truly minimal (~15 core extensions). If you use these extensions with slim, switch to standard.
igbinary removed — Abandoned upstream, unable to keep up with PHP releases. Redis falls back to PHP's native serializer. Users with Redis::SERIALIZER_IGBINARY must switch to Redis::SERIALIZER_PHP or Redis::SERIALIZER_MSGPACK.
Migration failure now exits by default — LARAVEL_MIGRATE_ENABLED=true will exit 1 on failure instead of continuing. Set LARAVEL_MIGRATE_ALLOW_FAILURE=true to restore the old behavior.

Custom command support — docker run myimage php artisan migrate now works. Entrypoint runs setup (permissions, framework detection) then execs the command directly, without starting the process manager.
Reusable CI workflow — _build-image.yml encapsulates the entire build-scan-test pipeline. Workflow YAML reduced from 3,976 to 1,610 lines (59% reduction).
Build dependency chain — workflow_run triggers ensure base → fpm → fpm-nginx builds in correct order (no more relying on staggered cron times).
Binary download script — scripts/download-cbox-init.sh downloads Cbox Init binaries for local development. Binaries removed from git (saves 35MB in repo).
Ready-to-use Dockerfile templates (Node.js, Development, CI/CD)
Rootless container documentation
Development environment with Xdebug + SPX profiler

Rebranded to "Cbox PHP Base Images" — consistent naming across all docs, README, and CLAUDE.md
Docker image layer optimization — Cbox Init binary no longer leaves dead layers (~17MB saved per image via multi-stage scratch approach)
php-fpm Dockerfile dedup — Shared dependency stages eliminate 8x apt-get duplication (491 → 381 lines per Dockerfile)
Entrypoint function dedup — Removed duplicate functions, consolidated with shared library
Reverb port in rootless mode — Changed from 8080 to 6001 to avoid conflict with rootless Nginx
CI timeout — Reduced from 8 hours (Alpine-era leftover) to 90 minutes
