The new version of Custom Properties is available.
The whole package, comprised of 1 component, 4 modules and 3 plugins, has been almost entirely rewritten for a better compliance with Joomla's platform modifications and to have a seamless integration with the new CMS interface.

We give great value to reliability, hence we spent a considerable amount of time and resource on testing to make Custom Properties 3 as reliable as its predecessors.
Works have been done to take advantage of Joomla module cache. In fact CP 3 appears to be faster than earlier versions, although we don't have numbers to backup our claim at this stage.
Whenever advisable, modifications have been done to the structure of the views to make customizations and overrides easier.
Our fellow developers will notice that there has been a good deal of code re-organization and rationalization. The list of modifications includes the migration of JS scripts from mootools to jQuery.
