The work on version 2.13 has now started and we are currently looking into what we want to include in the version. We have so far focused on fixing the reported issues as well as implementing the possibility of refreshable pages, so it is easier to update the data on certain pages. The whole changelog can be found in the forum: http://theairlineproject.net/forum/showthread.php?tid=1308

I hope that the next release will be out in the end of June/beginning of July.
