+## [1.3.1] – 2026-04-17
+
+### Fixed
+- **`add_comment` response parser**: corrected response structure from `a00.r.r` with `metaId`
+  to nested `a00.r.r.comment.commentId`; response now includes `"created": true` flag
+- **`add_comment` error handling**: now returns error messages directly instead of warnings
+
+### Added
+- **`delete_wall_post`** — permanently delete a wall post using the `metadelete` endpoint
+  (identical to deleting tasks and recipes)
+
+### Notes
+- All wall post tools now complete CRUD operations (Create, Read, Update via like_post, Delete)
+- Test post (wall/16282169_31146617) removed from production after verification
