• Releases are now automatically performed using Github Actions

Release 5.3.0

This release brings some major additions:

• The center of diffraction is now calculated and updated as needed automatically.
• Added the DiffractionDataset.mask_apply to modify the diffraction pattern mask.
• Windows installers are now built with pynsist/NSIS instead of PyInstaller (#15).
• Better handling of write permissions.
• Added the MigrationWarning and MigrationError classes. Warnings/errors of these classes tell the user that migration should be performed. This is automatically done by opening a DiffractionDataset with writing permission. The GUI does this automatically.

Some maintenance updates:

• Support for Python 3.6 and NumPy<1.17 has been dropped <https://numpy.org/neps/nep-0029-deprecation_policy.html>_
• Fixed an issue where creating the plug-in directory would rarely fail.

Release 5.2.5: SWMR on all platforms

This release brings one major change:

• Parallel operations on datasets (via HDF5 single-writer multiple-reader) is now possible on all platforms. It was previously limited to Windows.

Infrastructure changes listed below have lead to improvements to documentation and correctness:

• Code snippets in documentation are now tested for correctness.
• Migration of test infrastructure to pytest.
• Tests are now included in source distributions.

Release 5.2.4: support for h5py 3.*

This release adds support for h5py 3.*, so that you can now use h5py 2.* and 3.*.

Release 5.2.3: Python 3.9 support and relicensing

This release brings the following changes:

• Re-licensing iris-ued to GPLv3.
• Changed the default colormap for processed datasets, to visually distinguish between raw and processed data viewers
• Added support for Python 3.9
