Shipped Buildx v0.37.0-rc1 with native cloud driver support for Docker Build Cloud builds.

Buildx v0.37.0-rc1 added a "cloud" driver for Docker Build Cloud. Builds run through the service with no custom Buildx binary required. The release also:

• Fixed Windows platform identifier consistency with OS versions
• Made the Kubernetes driver skip terminating pods when choosing one
• Stopped creating temporary files on the host when sending builder config to remote containers

Compose v5.5.0 overhauled image digest reconciliation. Containers are recreated only when digests genuinely change, cutting churn. Existing containers may be recreated the first compose up after upgrading as digests re-evaluate. compose pull now honors pull_policy refresh windows (daily, weekly, every_N).

Compose v5.4.0 modeled volume and network lifecycle in the reconciliation plan. Resource changes are planned before they apply. The release also:

• Warns when a service selection is silently ignored
• Uses the platform image-manifest digest, not the attested index, for builds
• Honors --insecure-registry when up reloads the model
• Pins type:image volume sources and pre_start hook images

Buildx v0.36.0 added default source policy validation. Creating a docker-container builder validates BuildKit release image authenticity by default. Bake gained secret source overrides; source policies support array.flatten and OPA template strings. Broken builders are handled correctly on removal, and Kubernetes driver builds no longer hang when the remote exec stream ends. v0.36.1 followed with BUILDX_NO_DEFAULT_OCI_ARTIFACT as an alternative to oci-artifact=false, bumping BuildKit from v0.32.0 to v0.32.2.

Compose v5.3.0 shipped native init container support, running pre-start containers before service containers using native Compose syntax.
