Hi and welcome to the forum.
We are working on a detailed roadmap for 2013 and it will be published on our blog: http://epe.si/blog
We have over 200 outstanding tickets at this moment and they range from bugfixes and small issues to huge projects requiring a complete rewrite of some of EPESI components. All versions are backward compatible as it is the case since 2006 when we started working on it.
A brief list of chnages and additions we are considering (to give you an idea):
- PHP 5.3 only support (5.2 support will be dropped) because of namespaces, autoloader
- Rewrite Menu - store menu in a table
- Permissions on module level
- Utils/Attachments Permissions like in RB
- REST API - most likely utilizing http://www.slimframework.com/
- Further work on AdoDB - Active Records, Objective RB (RBO)
- Switching from QF to QF2 Quickform2
- responsive design template (see below)
- Kickstrap integration: Bootstrap, FontsAwesome, jquery, Raphael.js, Raphael charts (replacing open Flash Charts)
- Choosen instead of Multiselect
- Sabre VObject - to support ical, vcards
- rewrite calendar using Bootstrap's calendar
- further enhancements to Translation Engine
Some time in the future: websockets support, maybe using Ratchet: http://socketo.me/
The list is not complete and details are still being prepared.
