- Added Intra-frame insertion and cut detection
- Added instrumentation output from encoder and an instrumentation display tool for visualising encoder decisions to help with algorithmic development
- Added a unit testing framework based on cppunit for testing classes
- Added feature to encode only a section of input video rather than the whole sequence
- Tweaked motion estimation parameters to improve performance, mostly for higher-res pictures
- Fixed bug with vertical block separation always being set to 8 pixels
- Fixed bug 1008694 (Out-of-tree building fails)
- Fixed header and pkconfig installation
