Notable Changes

• Builtin Dockerfile frontend has been updated to v1.24.0-rc1 changelog
• BuildKit now supports the concept of "compatibility version" for improved reproducible builds support across different BuildKit versions. This allows users to specify a version for which the build should be compatible with, and BuildKit will attempt to maintain compatibility with that version when possible. Compatibility version will be stored in the provenance attestation of the build and can be used to independently verify the artifacts of the build on other BuildKit versions. The current compatibility version and backward compatibility with old versions are defined in Build reproducibility docs #6681
• Git sources now support fetch-by-commit option where commit is fetched by the SHA and then associated with the reference. This is useful when checking out mutable references refs/NR/merge where the commit SHA may change during invocation and cause checksum mismatch error #6708
• The LLB API now supports Git bundle format. Git bundles can be loaded from registry or OCI layout blobs and Git sources can be checked out into bundle format for snapshotting #6711
• Provenance attestations for multi-pass or chained builds now include request details for root requests and individual input requests, allowing full reconstruction of such complex builds #6739
• S3 cache now supports additional options retry_mode and retry_max_attempts to configure retry behavior of S3 client #6657
• S3 cache now supports disable_accept_encoding option for GCS interoperability #6642
• Reduce potential lock contention in gateway forwarder for improved performance on parallel builds #6741
• A new log level option has been added to the buildkitd TOML configuration; previous "debug" and "trace" options have been deprecated #6732
• Allow gateway frontend requests to forward to the built-in Dockerfile frontend the same way as to external frontends #6643
• In special modes where the client does not expose the session connection to transfer credentials, builds can now still fall back to anonymous registry auth instead of erroring #6744
• Session connection health checks have been improved to better detect loss of connectivity and avoid stuck builds #6649
• Fix issue with Git subdirectory value not being included in ConfigSource section of SLSA provenance for builds from Git sources #6724
• Avoid potential deadlock if the credential helper in the client is misbehaving and never returns credentials #6709
• Fix possible data race in progress writer #6679
• Fix data race in S3 cache reader #6675
• Fix possible Git config lookup errors on Windows #6639
• Fix build cancellation not working properly when blocked on credential callback #6641

Notable changes

• Dockerfile now supports special arg definitions SOURCE_DATE_EPOCH=context and SOURCE_DATE_EPOCH=<stage> which set the value of SOURCE_DATE_EPOCH to the timestamp associated with the remote context or the stage respectively. When building from a Git commit, the context timestamp is the commit timestamp, and when building from a remote URL, the timestamp is resolved from the metadata of files in the TAR archive or from the Last-Modified header of the URL #6602
• Fix issue where in some cases LABEL value could incorrectly leak from stage linked via COPY --from #6713
• Formatting of History entries for HEALTHCHECK instructions has been fixed #6664

Notable changes

• Git URLs now accept the mtime=commit query parameter to initialize checked-out file timestamps to Git commit time. Remote builds using a Git context that define SOURCE_DATE_EPOCH automatically default to mtime=commit for better reproducibility. #6600
• Dockerfile can now define SOURCE_DATE_EPOCH build-arg in the global scope with a default value. The value can still be overridden with --build-arg as before. #6601
• Fix issue with the order of applied proxy build-args being non-deterministic #6560
