This 'release' contains a lot of bug fixes (thanks to traumschule, bug finder extraordinary) from the November one. No major structural changes but it does now provide a means to make a default directory in which notes would ordinary be stored.
It is strongly recommend you look at the Tomboy wiki, especially the tomboy-ng part before downloading and installing.
Note we now have a simple deb for Debian based Linux users, a better Mac installer and the remained are now "ziped" for easy download.
