Version 0.6.1 (Oct 5 2010):
* Exposed ExponentTransform
* Added CineonLogToLinTransform - a simple 'straight-line'
negative
linearization. Not strictly needed (could be done previously
with LUTs) but often convenient to have.
* Added DisplayTransform.displayCC for post display lut CC.
* Many python improvements
* A few bug fixes
* A few Makefile enhancements
