 ### Bug fixes
 
 - Fixed submitting local JCL using command pallet option `Zowe Explorer: Submit JCL` by adding a check for chosen profile returned to continue the action. [#1625](https://github.com/zowe/vscode-extension-for-zowe/issues/1625)
+- Fixed issue where USS nodes were not removed from tree during deletion. [#2479](https://github.com/zowe/vscode-extension-for-zowe/issues/2479)
+- Fixed issue where new USS nodes from a paste operation were not shown in tree until refreshed. [#2479](https://github.com/zowe/vscode-extension-for-zowe/issues/2479)
+- Fixed issue where the "Delete Job" action showed a successful deletion message, even if the API returned an error.
+- USS directories, PDS nodes, job nodes and session nodes now update with their respective "collapsed icon" when collapsed.
 - Fixed bug where the list of datasets from a filter search was not re-sorted after a new data set was created in Zowe Explorer. [#2473](https://github.com/zowe/vscode-extension-for-zowe/issues/2473)
