 # Changelog
 
+## 2026-02-06 - 1.12.0 - feat(docker)
+add detailed logging for buildx, build commands, local registry, and local dependency info
+
+- Log startup of local registry including a note about buildx dependency bridging
+- Log constructed build commands and indicate whether buildx or standard docker build is used (including platforms and --push/--load distinctions)
+- Emit build mode summary at start of build phase and report local base-image dependency mappings
+- Report when --no-cache is enabled and surface buildx setup readiness with configured platforms
+- Non-functional change: purely adds informational logging to improve observability during builds
+
 ## 2026-02-06 - 1.11.0 - feat(docker)
 start temporary local registry for buildx dependency resolution and ensure buildx builder uses host network
