Multiple exporters(outputs) can now be specified with a single build request #4134
New option rewrite-timestamps is available when exporting images that with convert files in exported layers according to the epoch time for reproducible builds #4057 docs
There is a new bridge network mode --oci-worker-net=bridge that can be used to set up CNI bridge networking with no external dependencies for better network isolation of build containers. It is expected that v0.14.0 release will enable this network mode by default. #4352 #4650 #4539

Github Actions cache backend now supports defining timeout in case the service gets rate-limited #4702
Gateway API has a new method ResolveSourceMeta that will replace the previous ResolveImageConfig method. The new method works with all LLB source types, not just images, and correctly handles policy conversions between sources. #4563 #4647
When using host networking, local host DNS routes can also be used instead of the default #4524
Changing cache mount's ID property does not invalidate cache for the build step anymore #4585
Basic metrics support has been added via OpenTelemetry and Prometheus #4460
Token cache is no longer shared between parallel push requests #3592
Update insecure registry fallback logic to only fallback with previous host #4613
Build secrets can now avoid noexec mount restrictions if file mode set execution bit #4670
GRPC socket for OpenTelemetry tracing now defaults to runtime directory path #4078 #4619
LLB API now has new options to directly control how different mounts for container steps are cached #4624
Cancellation and timeout errors should now contain better stacktraces on --debug mode #4587 #4457
Edge case of empty multiplatform build result does not generate errors anymore #4526
Prune command now avoids taking database lock for a long time if deletion takes too much time #4413
Healthcheck service has been added to Control API #4145
Buildctl has new quiet and rawjson progress mode #4213 #4113
Buildctl has new --debug-json-cache-metrics debug option #4464

Buildctl now propagates SOURCE_DATE_EPOCH to build arg automatically if it is defined #4231
LLB client now allows exposing local sources via FS interface instead of local path #4094
Ensure only one platform is pulled on resolving image config, even if multiple match #4311
Rootless version supports new --detach-netns mode #4546
Update default CNI config path for rootless mode to ~/.config/buildkit/cni.json #4547
Ensure correct pinned commit is checked out if tags that have same path components #4473
Exporting caches for results with no layers is now skipped in OCI structures #4336
New debugging options have been added to the scheduler component #4410
Improve error messages on StatFile requests #4321
Daemon logs can now be exported in JSON format #4044
Qemu emulation for loongarch64 is now detected if available #4392

Empty OnBuild value is now omitted from image config #4648
Fixes for bridge networking on Rootless mode #4655
Fix possible "missing lease requirement" error on canceling one of parallel exports #4529
Fix file permissions error if ADD <tar.gz> used with User namespace #4712
