+## 2.1.53
+
+- Fixed a UI flicker where user input would briefly disappear after submission before the message rendered
+- Fixed bulk agent kill (ctrl+f) to send a single aggregate notification instead of one per agent, and to properly clear the command queue
+- Fixed graceful shutdown sometimes leaving stale sessions when using Remote Control by parallelizing teardown network calls
+- Fixed `--worktree` sometimes being ignored on first launch
+- Fixed a panic ("switch on corrupted value") on Windows
+- Fixed a crash that could occur when spawning many processes on Windows
+- Fixed a crash in the WebAssembly interpreter on Linux x64 & Windows x64
+- Fixed a crash that sometimes occurred after 2 minutes on Windows ARM64
