Lots of updates - so here are the details:

Lighthouse Pro
Just changed the case of one SQL statement. Download from the project page.

Soundings
Fixed a bug in matrix display. Download from the project page.

Blog Beta
Fixed a bug with editing. Fixed mysql install script. Other misc small stuff here and there. (Thanks to Oguz and others for finding bugs.) Download here.

Just an FYI, Rob Brooks-Bilson had a few good ideas so there will be one (maybe two) new features in the next update. So blame him for delaying "official" 4.0 launch. ;)
