@@ -21,6 +21,7 @@ The newest entry must match the version in `WandEnhancer/Properties/AssemblyInfo
 
 - Fixed the "Buy Pro" banner still showing after a successful patch, and Pro not activating on newer clients.
 - Fixed the Enhancer closing itself when any button was pressed. #184
+- A failed patch now puts your original Wand files back instead of leaving a half-patched install behind. Packing also builds the archive beside the old one and swaps it in at the end, so a failure can no longer destroy `app.asar`. #221
 - Fixed a half-written backup reporting the installation as patched, which blocked patching and restore at the same time.
 - Fixed invalid ASAR integrity metadata produced from short reads, which could yield an archive the client rejects. #170
 - Fixed the packer silently dropping files it could not read, for example while Wand was still running.
