The first change in this version is a change to the installation process. Previously, you had to manually edit your EXTRA.css template to include the CSS for this add-on. This is now done automatically. Previous users should remove this line from their EXTRA.css template:
<xen:include template="sos_bbcodes.css" />
Secondly, buttons will now be added to the editor toolbar for these bb codes. You can remove these if you do not want them.
