Dear developers
I just updated the jQuery UI version shipped with Roundcube core to version 1.10.4. The change from 1.9.5 unfortunatlely implies some API changes which are all documented here: http://jqueryui.com/upgrade-guide/1.10/
Please review your plugins and patches for compatibility issues with the changed API!
For now the $.uiBackCompat mode is still enabled but we like to keep up with the stable releases from jQuery UI where more API changes are to be expected. So be prepared for that :-)
Kind regards, Thomas
