• Detectors are now able to guess the binning
• Support of multiframe EDF for diff_tomo
• Tested on windows 64 bits, MacOSX 10.6 and 10.6, debian 6, 7 and 8. Arm, PPC64LE, i386, amd64, with python 2.6, 2.7, 3.2 and 3.4. The test do not pass under windows 32bits due to the 2GB limit (nor under linux with 1GB of memory)
• Better support for detectors with gaps.
• Bunch of new calibrants (14 in total now)
• Sorting on GPU (works only under linux for now)
• Eiger detectors (masks, ...)
• Versoning tool (_version.py)
• Segmentation of the documentation: user/developer/administrator
• Clean up on the OpenCL side (factorization)
• Better workers and support for HDF5 input/output
• Tests are available in installed library: pyFAI.tests()
• Separation of third party code: argparse, six, ...
• Watershed based segmenter for peak-picking (work ongoing)
