QVCS is a version control system. With QVCS you can: store/retrieve file revisions; insert keywords into your source code or binary files for automated documentation and audit trail generation; use a global journal file to keep track of all changes to files in your project(s); keep track of who changed what, and when they changed it; label revisions for a release; restore a project to an earlier labeled release; allow modification access to files on a file by file basis; compare files to earlier revisions or compare revisions to other revisions; create a parallel development branch (branching); merge edits made to the same revision.

The update improves use of project level label cache so gets, checkouts, labels, and unlabels are faster to use.
