No. The reason is simple: the public svn repository does not cover any 
VirtualBox release branches, it only contains the development "trunk". 
Sure, most changes in a release branch are backports of a nearby trunk 
change, but that's not guaranteed. Sometimes it takes months of testing 
and improvements until we consider a change good enough for production.

For releases, we provide a tarball, so you can at least figure out what 
changed between 4.2.20 and 4.2.22.
