v0.2.4

Fixed

• Blob verification now uses HEAD requests to reliably detect missing blobs
• Post-write verification uses light manifest check to avoid false failures
• Fixes issue where Quay GC could delete blobs but old verification missed it

See CHANGELOG.md for full history.

v0.2.3

Fixed

• Blob verification now actually reads from layer blobs instead of just checking manifest metadata
• Removed Windows binary download from mirror-local.sh (not included in container images)

See CHANGELOG.md for full history.

v0.2.2

Fix: Push images with permanent tags instead of digest-only (which Quay garbage collected)

v0.2.1

Fix: Verify ALL layer blobs exist before skipping. Previous version could skip images with missing layers.
