Weekly Documentation Audit — 2026-06-23

Supersedes #18.

Documentation gaps identified

• CHANGELOG.md [Unreleased] section was empty despite two PRs landing since v0.2.0
• Docker registry migration (PR chore: rework goreleaser for dockers_v2 #14) and GHA version bumps (PR chore: bump gha versions #13) were not reflected in the changelog
• No version bump had been proposed for the user-visible registry URL change

Changes made

CHANGELOG.md — Added to [Unreleased]:

• Docker registry migration (PR chore: rework goreleaser for dockers_v2 #14): container images now published to ghcr.io/krakenkey/cli (was docker.io); manifest format changed to docker_v2; pull commands in documentation need updating
• GHA version bumps (PR chore: bump gha versions #13): docker/setup-qemu-action v3→v4, docker/setup-buildx-action v3→v4, docker/login-action v3→v4, goreleaser/goreleaser-action v6→v7

Status note

#18 remains open and unmerged. This edition carries forward the same gaps — the fixes are now on branch claude/friendly-meitner-q4s61x. Close #18 once this PR is reviewed.

Suggested version bump

v0.3.0 — the registry URL change is a user-visible breaking change for anyone pulling images by the old docker.io path.
