+## [0.1.2] — 2026-09-26
+
+### Fixed
+
+- Uninstall now drops `wp_hpct_latepoint_idx` (every site on multisite) and the
+  `tmdo_latepoint_db_version` option. 0.1.1 started creating the table, but
+  `uninstall.php` was still the Phase 0 stub and left it behind. The table is
+  an index rebuilt from LatePoint's bookings; LatePoint's own tables are kept.

 ## [0.1.1] — 2026-08-08 — 補上從未存在的 `wp_hpct_latepoint_idx` 建表流程
