 # Changelog
 
+## Version v0.1.2
+### Features
+ * Users can edit or delete labels created by themselves on the labels page
+ * Administrators can edit labels from the admin interface
+ * Filter label visibility so logged-in users only see default/admin-created labels and their own
+ * Grandfather tags with unknown ownership as default/admin interface labels

 ## Version v0.1.1 
 ### Features
  * Ability to add new logs through the web interface

 ### Assistant outcome
 Appended the release workflow changes and this VIBE update request to `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md` in the existing append-only format.
+
+### User
+I want that the users is able to edit or delete labels(tags) that were created by the user itself. Also validate that any logged in user will only see the labels created by default, in the admin panel, and those by themselves, not by any other user. If this leads to an update in the database then if ownership of labels is unknown they may be grandfathered as-if created in the admin interface
+
+### Assistant outcome
+Implemented creator edit/delete rights for user labels on `/labels` and `/api/user/labels/{label_id}`, isolated label visibility so logged-in users only see default/admin labels and their own created labels, dynamically set `created_by` when new tags are saved from links, grandfathered existing tags with `NULL` ownership as default/admin labels, added `frontend/static/labels.js`, and expanded unit test coverage.
+
+### User
+Make sure that in the admin interface the labels can be edited
+
+### Assistant outcome
+Added `PUT /api/admin/labels/{label_id}` for administrator label renaming, updated `update_label` service function to accept `is_admin=True`, added inline edit controls to `frontend/static/admin.js` for administrator label management, and added regression test coverage.
+
+### User
+Make sure that the logs in VIBE are updated
+
+### Assistant outcome
+Updated `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md` with the recent user prompts and assistant outcomes.
+
+### User
+Update Changelog too
+
+### Assistant outcome
+Updated `CHANGELOG.MD` with the recent feature additions (user label CRUD, label visibility isolation, grandfathering unknown label ownership, and administrator label editing), and updated `VIBE/PROMPTS.md` and `VIBE/CHAT_LOG.md`.
