Hi,
I have to admit that we are on the right track to finalize all scheduled work for 4.4 so far. In my opinion most of the work should be done within couple of weeks so I would say that end of June sounds like a good date for 4.4 release (just to be on safe side).
Unfortunately I am not in charge so we have to wait for Alejandro opinion but hopefully we will manage to deliver a stable 4.4 release with bug fixes and so enhancements as well (mainly those that have been already implemented).
Besides bug fixing we are trying to put some focus on documentation as well, especially for these elements that have been asked several times on the forum.
Please refer to JIRA for the latest status and feel free to comment and vote ... there is still some issues left ;)
Cheers,
Maciej
