Notable changes

Please try out the release binaries and report any issues at

Notable Changes

• Unfortunately, we had to revert the change that added new object notation for the fields that previously required CSV strings in Bake definition because of backwards incompatibility issues were discovered in some edge cases. This feature has now been postponed for future v0.20.0 release #2824

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 an error starting from the v0.20 release. If you wish to enable the error in the current release, you can set BUILDX_BAKE_ENTITLEMENTS_FS=1 #2796 #2812
• Bake definition now supports 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 an incorrect format for labels #2778
• FreeBSD and OpenBSD artifacts are now included in release #2774 #2775 #2781
• Fix printing bake definition with empty Compose networks #2790
