v0.30.0
v0.30.0 is a maintenance release: Go 1.27, the whole dependency graph brought current, and the codebase modernized to the Go 1.26 idioms.
Toolchain
The Go toolchain moved to go1.27.0; the supported minimum stays Go 1.26 (#800). Two lint classes surfaced under the new toolchain and are resolved in the same change: gofumpt's new closing-paren placement, and six //nolint:goconst directives that goconst no longer needs.
Dependencies
The scheduler core netresearch/go-cron moved to v0.16.0, its first release with the Go 1.26 floor (#802). The rest of the graph followed: docker/cli 29.7.2, emersion/go-smtp 0.25.0, moby/moby/client 0.5.1, testify 1.12.1, golang.org/x/crypto 0.55.0, golang.org/x/text 0.41.0 plus indirect moves (#801), and the harden-runner action group (#799).
Internal
go fix and manual passes modernized the code — strings.Cut, slices.Backward (with the safety argument documented at the removal loop), maps.Copy, errors.AsType[T], atomic.Int32 in tests — with no behavior change (#800).

sha256sum -c checksums.txt --ignore-missingVerify build provenance. Releases are built by a reusable
workflow, so the signing identity is that workflow rather than
this repository -- --signer-workflow is required and
verification fails without it:
