In addition, it also manages memory slightly better now, and has minor documentation typo fixes.

 	* **Alpha 4 is finally here.** Everything from Alpha 3.5 and what's listed below is in this release; the two biggest changes are still the new text drawing API and new uiTable control. In between all that is a whole bunch of bugfixes, and hopefully more stability too. Thanks to everybody who helped contribute!
 	* Alpha 4 should hopefully also include automated binary releases via CI. Thanks to those who helped set that up!
