What's new in this version:

Interface:
- Image editor scope and clip editor track preview did not resize properly with different DPI settings.
- Alt+MouseWheel changes frame as well as buttons
- Fix UI/DPI: user preferences window size now takes into account DPI, otherwise the buttons don't fit properly.
- Fix soft shadow at top edge incorrectly drawn
- Screencast could be started twice
- Panel color were not updated from old files properly
- Allow trackpad and magic mouse swipes to control brush size for circle select.
- Window position not saving correctly for next start-up
- Quicktime video codec menu showing blank

Viewport:
- GLSL materials using multiple UV layers fail in edit mode
- View3D Mini-Axis drawing in error with overlay
- Manipulator handles drawn incorrectly by depth
- Fix glitch rotating the camera in camera mode drawing helper-line in random locations

Animation:
- Fix zoom for graph-editor (and other editors)

Sequencer:
- Strip modifier - Mask multiply failure
- Added RGBA|RGB channels toggle to sequencer preview
- Fix sequencer crash when pasteing strips after creating new file

Composite/Nodes:
- Inputs list in file output doesn't appear properly.
- Crash when using image output node
- "Record Composite" image op segfaults in compositor code
- Inconsistent behavior of "Color Mix Node" and "Alpha Over Node"
- Adding reroute node into invalid links would crash the compositor

MovieClip/Tracking:
- Fix memory leak when loading multilayer EXR as movie clip
- Fix for incorrect subpixel precision of marker when using track offset

Render:
- Displacement map Bake margin does not work
- Node editor delete texture crash
- Image Sequence texture didn't allow "Offset" with fcurves.
- Weird noise bug with Texture nodes

- Fix image transparency backwards compatibility. Now the texture datablock has a 'Use Alpha' option again.

Render (Cycles):
- Viewport render stuck with no objects in the scene.
- Hair render in dupligroup did hide the emitter properly in some cases.

Modifiers:
- Shrinkwrap modifier project along normal did not work correctly
- Applying screw modifier turns object to black

Tools
- Border select in UV Image window crashed
- Fix for weight paint using values over 1.0 when blending
- Fix for regression in 'object.shape_key_transfer' operator since BMesh merge
- Edge slide results in segmentation fault on certain mesh
- Origin to Center of Mass is missing in menu Object > Transform
- Fix selecting linked faces
- mesh.select_mode operator could not be configure the use_extend and use_expand properly.

- Fix joining meshes could loose crease/bevel weights
- Fix (regression) #34449: Edge toggline bevel failed

Sculpt:
- Collapse-Edges crash in dyntopo
- Crash when dyntopo enabled and using view plane mode
- Blender Crashes on toggling modes, dynatopo sculpt/object mode.

- Fix projection clipping
- Character walkDirection ADD mode -#INF error.
- Enable alpha buffer (useful for TV broadcasting).
- Ray cast on Triangle mesh bounded Rigid Body Object crashes
- Webcam support under Linux in Standalone broken
- Action Actuator "caching" the previous ran actions
- Fix error using actions with multiple scenes
- Fix object color channels can now be animated separately without zeroing out the other channels
- Fix error using uninitialized variables for rendering
- Game-Engine - Multi UV mesh's materials not backwards compatible
- Fix Game-Engine crashing when on material conversions
- Motion blur (2d filter) not working in osx
- Fixed error with converting multi-uv layers.
- 2D-Filter produces render error
- 2D-Filter causes mouselook script drifting effect

Rigid Body:
- Fix motion paths calculation being incorrect for rigid bodies
- Allow rigidbody collision groups to be animated
- Planes with Rigid Body always keep distance to colliding objects
- Rigid objects not resetting original properly after running a simulation.
- Fix inconsistency with world rebuilding with the start frame

Text Editor:
