New

  • Set Buildx and BuildKit as the default builder on Linux. moby/moby#43992
    • Alias docker build to docker buildx build. docker/cli#3314
    • The legacy builder can still be used by explicitly setting DOCKER_BUILDKIT=0.
    • There are differences in how BuildKit and the legacy builder handle multi-stage builds. For more information, see
      Multi-stage builds.
  • Add support for pulling zstd compressed layers. moby/moby#41759, moby/moby#42862

Bug fixes and enhancements

  • API: containers/{id}/attach/ws only to streams according by stdin, stdout and stderr parameters on API version >= 1.42. moby/moby#43322

  • Improve the reliability of the daemon dumping the stack and exits with code 2 when sent a SIGQUIT. moby/moby#44831
  • Fix a rare deadlock in the daemon caused by buffering of container logs. moby/moby#44856
