+# ForgeFlow 0.4.4
+
+## Correct Git change handling
+
+- Deleted files are staged with `git add -A` and are removed from Gitea after commit and push.
+- Renames include both the new path and original path when staging or unstaging selected changes.
+- A failed staging action always reloads the real repository state so changes remain visible.
+- When commit succeeds but push failed, ForgeFlow clears obsolete file selection and shows the clean working tree as an ahead branch with a dedicated retry push action.
+- Added real bare-remote regression tests for deleted files, renames, and push-after-commit failure recovery.
