This section summarizes the changes between Oracle VM VirtualBox versions. Note that this change log is not exhaustive and not all changes are listed.
Oracle VM VirtualBox version numbers consist of three numbers separated by dots where the first and second number represent the major version and the third number the minor version. Minor version numbers of official releases are always even. An odd minor version number represents an internal development or test build. In addition, each build contains a revision number.
This is a maintenance release. The following items were fixed and/or added:
-
VMM: fixed guests hanging under certain circumstances when Hyper-V is present (bug #20141)
