I am working with a version 4.0 Umbraco website and am looking to upgrade it. It is probably going to be replaced with a new version soon, but for now it needs to carry on working.

One major issue with this version is that the delete option on the content area context menu sometimes gets it wrong and deletes a node higher up in the tree to the one you actually right clicked.

I know this issue has been fixed, but I can't remember what version ... this is the version I want to upgrade to (at least). Can anyone remember what version it was?
