+## 3.2.1 (February TBD, 2026)
+
+- Bug Fixes
+ - The `async_alert` and `async_prompt_update` methods of `cmd2.Cmd` now respect the current
+ value of the `allow_style` settable
+ - If `allow_style` is `NEVER`, all ANSI escape codes will be stripped to ensure plain text
+ output
+
 ## 3.2.0 (February 5, 2026)
 
 - Bug Fixes
