getgrav/grav 1.8.0-beta.30 on GitHub

Added family-aware GPM upgrade gate: blocks cross-major.minor auto-upgrades (e.g. 1.8 → 2.0) and points users at the migrate-grav plugin
Added next_major hint surfaced from the remote GPM feed so admin/CLI can display upcoming major-version availability
Added compatibility blueprint support for major-version upgrade gating
Added media:// stream for a site-level media directory
Added fast static asset serving for plugin-bundled SPA apps
Added onFlexDirectoryConfigBeforeSave event
Added cache-cleanup CLI command
Added -v verbose flag to yamllinter command
