New features: Graphical user interface for calibration (pyFAI-calib2) Goniometer calibration tools and multi-geometry enhancements Integration scripts and averaging scripts are now able to normalize the data from monitors found in the header. Propagate metadata information as part of the integrated data Common pre-processing factorization on Python, Cython and OpenCL Test clean up and acceleration (avoid tests on too large images) Many new tutorials http://pyfai.readthedocs.io/en/latest/usage/tutorial/index.html New averaging / integration methods: Azimuthal median filtering Azimuthal trimmed mean sigma-clipping on azimuthal angle Radial averaging Diffraction image inpainting to fill-up the gaps with plausible values.
