 # Change Log
 
+## 0.0.5
+- fix: ignore corrupt workspace-state
+  - when we load the sub-workspace vscode forcefully reloads the extension. To avoid any inconvenience e.g. because calling "decompile" appears to have no action we replay that command once we're reloaded. that command is stored in the workspace for 30secs (file to be decompiled on reload).
+  - in case the workspace state is corrupt the extension would permanently throw. this changeset is adding safeguards to avoid that the extension cannot be used anymore because of a corrupt workspace state.
+
 ## 0.0.4
 - new: multi-select decompilation
   - select multiple items and click `decompile` to decompile them in parallel
