Econ Technologies today announced the release of ChronoSync 3.3.1, the automated synchronization and backup application for Mac OS X. This maintenance release fixes several bugs and adds a few new features. Version 3.3.1 fixes problems with synchronizing locked packages, long filenames, and file attributes; corrects various translation errors and user interface glitches; and the the ability to synchronize the modification dates of folders is now an optional setting and not required. ChronoSync is priced at US$30, and a free demo is also available.
