 # Moka Cache — Change Log
 
+## Version 0.12.6
+
+### Fixed
+
+- Fixed a bug in `future::Cache` that pending `run_pending_tasks` calls may cause
+  infinite busy loop in an internal `schedule_write_op` method
+  ([#412][gh-issue-0412]):
+    - This bug was introduced in `v0.12.0` when the background threads were removed
+      from `future::Cache`.
+    - This bug can occur when `run_pending_task` method is called by user code while
+      cache is receiving a very high number of concurrent cache write operations.
+      (e.g. `insert`, `get_with`, `invalidate` etc.)
+    - When it occurs, the `schedule_write_op` method will be spinning in a busy loop
+      forever, causing high CPU usage and all other async tasks to be starved.
+
+### Changed
+
+- Upgraded `async-lock` crate used by `future::Cache` from `v2.4` to the latest
+  `v3.3`.
