I just uploaded a new release of ConTagged, our Open Source LDAP address book. If you used ConTagged before you may notice the version leap from 0.4 to 0.6. To be honest I'm totally lost with deciding on version numbers. Looking at the changes, this release could have been named 2.0 as well.
The most important thing that changed is how data storage is handled. Previously ConTagged was pretty much hardcoded to use a certain LDAP scheme for creating contacts. There were a few extensions to add additional attributes but this was all very hackish. In the new release you can redefine all attribute names and object classes in a single file. You even extend it to add your own (needs a some simple template editing). This change should make it easily possible to combine ConTagged with existing solutions like OpenXchange or Evolution.
Many fields now have auto completion and images are shown inplace using the famous lightbox effect. And because all that was not Web 2.0 enough, I added Google Maps support on top .
Did I mention the code cleanup and file layout restructuring? Yes, did that, too.
Now go and get it! You know you want it
