Nevertheless, it has also new features and not only bug fixes. For those that work with the OpenGL Viewport
a lot, they can now start a region render (in the darkroom) by selecting an area in the Viewport. You have to
click on the tool drop down menu and select the Region first, then left-click and drag to select the area
to be rendered. Even more, as a workflow optimization, you can now pin the tools/navigation drop-down
menu (a new menu appears above the compass), so you can quickly make a selection!
Another cool UI addition is locking camera aspect ratio; something very small, yet asked for so many times!
There are also various fixes for Relight and also displacement mapping is now rock solid.

The point lights can now be also described in terms of Power/Unit/Efficacy, establishing a uniform
description between point and area lights. On top of that, there is a crucial bug for all unbiased engines
(and IR included) that was adding wrong noise when rendering with 2+ threads - this is now fixed
and it basically means faster renders when using TR1/TR2/IR!
