There are a lot of changes, most of them not yet documented:<br />- updated to work with with CMSMS 2.x series;<br />- BBCode should work out of the box (may currently break compatibility with JM_BBCode module);<br />- added a palette of emoticons with the respective parser;<br />- added uploads of attachments to posts;<br />- templates are now separated from the settings (not yet on DM for backwards compatibility);<br />- and more...<br />This should be the last branch compatible with CMSMS 1.12.X, although updates and stability releases may be expected for sometime (at least a year from stable release but not much longer);
