 ### Added
-
 - Edit last broadcast message with `editLastBroadcastForAll()`.
 - Optional `broadcastId` targeting for editing or deleting the last message of a specific broadcast.
 - Metadata peer loading for targeted edit/delete calls when `allUsers` is empty and `broadcastId` is provided.

 ### Changed
-
 - Safer state handling using shared state references by broadcast id.
 - Safer cancel behavior: `cancel()` now marks cancellation without clearing in-flight requests.
 - `progress()` now includes edit, scheduled, self-destruct, total, elapsed, and TPS fields.

 ## [3.2.1] - 2026-06-13
 
 ### Added
-
 - Added support for editing last broadcast messages with media loaded from `data/{adminId}/media.txt`.
 - Added compatibility for passing saved media values / `botApiFileId` into `editLastBroadcastForAll()`.
 
 ### Changed
-
 - Relaxed the `$media` parameter in `BroadcastManager::editLastBroadcastForAll()` so it is no longer limited to `?array`.
 - Edit-last-broadcast flow can now reuse the same saved media format used by regular broadcast sending.
 
 ### Notes
-
 - Passing `null` as media keeps the existing media unchanged.
 - Passing a saved media value attempts to update the edited message media/caption.

+## [3.2.2] - 2026-06-15
+
+### Changed
+* Reduced default broadcast concurrency from `20` to `10`.
+* Reduced the maximum allowed concurrency limit from `50` to `30` to reduce pressure on the MadelineProto event loop during large broadcasts.
+* Progress status messages are now edited every `5` seconds instead of every second.
+* Progress status updates now also perform a final update when the operation reaches completion.
+* Slowed down broadcast workers with a small delay between processed jobs.
+* Added a delay after each media album chunk sent with `sendMultiMedia`.
+* Added a delay between sequential messages sent to the same peer.
+* Broadcast control buttons are now displayed in English:
+  * `Pause`
+  * `Resume`
+  * `Cancel`
+
+### Fixed
+* Reduced the chance of `Timeout while waiting for updates.getChannelDifference` after heavy broadcasts.
+* Reduced unnecessary progress-message edit calls during active broadcasts.
+* Prevented noisy logs for harmless `MESSAGE_NOT_MODIFIED` errors during progress updates.
+* Improved progress update stability by ignoring unchanged status edits instead of logging them as failures.
+
+### Notes
+* This release keeps the custom BroadcastManager flow, including saved message IDs, edit-last-broadcast, delete-last-broadcast, scheduled broadcasts, and self-destruct broadcasts.
+* This is a stability and load-reduction update; it does not migrate to MadelineProto's official Broadcast API.
