I love all of the features of UddeIM and made a donation for the premium pack a while back to continue to support development work. Some of the cb plugins for UddeIM 3.4 report that they are not compatible with CB 2.0 when installed, so curious if you have an idea of when updates may be available?

All plugins should work fine with CB 2.0 (final).

Which plugin reports that it does not work properly? When it is cb_plug_pms_uddeim please download the current version from the SVN trunk which should work even with CB 2.0 RC.

it seems that this plugin does not work with CB 2.0 stable.
When published (even latest SVN version) I get mysql errors such as :

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'delayed=0 AND toid=57' at line 1 SQL=SELECT count(id) FROM yq0g1_uddeim WHERE toread=0 AND delayed=0 AND toid=57

When unpublished and standard CB mypms is used, it seems impossible to send an uddeim message using message tab.

May be some incompatibilty with CB 2 somewhere ?

This is quite simple to fix:

In pms.uddeim.php line 398 add single quotes to the field name "delayed":

Thanks !

Do you still recommend using the latest svn build or not ?

In the latest build there is a new feature available that might be useful (system tab: additional admin and special user groups). Maybe you are interested in doing some tests
