Notable Changes

• Bake command now requires passing filesystem entitlements with --allow when your build needs to read or write files outside of your current working directory. This feature currently only reports a warning when using local Bake definition, but will start to produce error starting from v0.20 release. If you wish to enable the error in current release you can set BUILDX_BAKE_ENTITLEMENTS_FS=1 #2796
• Bake definition now support new object notation for the fields that previously required CSV strings as inputs (output, cache-from, cache-to, secret, ssh) #2758
• Bake definition now allows defining validation conditions to variables #2794
• Compose support has been updated to v2.4.4 #2806 #2780
• Metadata file values can now contain JSON array values #2777
• Improve error messages when using incorrect format for labels #2778
• FreeBSD and OpenBSD artifacts are now included in the release #2774 #2775 #2781
• Fix printing bake definition with empty Compose networks #2790
