Mouse wheel support for all windows. Two user settings are added in the top window for mouse wheel usage. The zoom direction [WZoom] and the number of lines that get scrolled [WLines] can be set here. The mouse wheel also works to increase/decrease the size of the circle while selecting or doing proportional scaling.
A "fake user" button next to the databrowse buttons has been added, to keep the data when it has been unlinked from an object. (Basically a shortcut for pressing Shift+F4 and F)
Added support for manipulating Ipo bezier handles through the action window. Selecting action keys and pressing V, H, or Shift+H modifies the handles of the keys in the same way it does in the IPO window.
Pressing C in the action window scrolls the window so that the current frame is in the center.
Extra selection support for the action window, including:
border select initiated in the channel names border selects the channels and constraint channels.
right click or border select initiated in the horizontal scroll causes blender to select all keys for the selected frames.
right click or border select in the vertical scroll causes blender to select all keys for the channel or constraint channels that are to the left of the selection.
X-ray bones support for showing armature bones in shaded mode (disabled depth test). The new x-ray button is added in the edit buttons when the armature is selected.
Pressing T in the action window changes the Ipo type (constant/linear/bezier) for the Ipo curves owned by the selected channels
Simple shaded+wire and solid+wire draw modes. It basically draws the wireframe after drawing the model in solid/shaded/textured mode. The user can set this per object using the "Wire" button in the edit buttons window.
A header button for drawing line numbers in the texteditor.
Ctrl keystrokes for cut/copy/paste/undo/redo in the texteditor.
NTSC render preset (Image size - 720x480, Aspect ratio - 10x11, 30 fps)
Make switching to bottom, back, and left view (Shift+Numpad 7, Shift+Numpad 1 and Shift+Numpad 3) work when in camera view.
Full screen by default under Unix.
Ignore WM_DELETE_WINDOW on IRIX.
Icons in the imageselect window get drawn properly.
Alleviation of the symptoms of the "slow render bug" by polling less often for the escape key in the inner loops of the render code (makes the escape key less responsive though).
RGBA Targa files get displayed correctly in The GIMP
A small modification is made that prevents closing the renderwindow on Mac OSX, so the GUI won't become unresponsive.
The Blender210 Python API. The only API which is available in 2.26 is the one that was used in 2.25
New build system using configure (this is partially working but needs some work)
Physics support in the game engine
