Documentation

• Fix a bug with the conda package.

• Drop support for Python <= 3.8.
• Support for the latest versions of all dependencies including Python 3.11.
• Internal code modernization.

• Fix an issue when appending waveforms of less than one second in length.

• Workaround for an issue with HDF5 on PPC64.

• Use a different way to copy the StationXML data in the process() function so it no longer gets stuck for large runs with MPI. See #62.

• Replaced some numpy functionality that will be deprecated in future numpy versions.
• Warnings will now raise when running the tests.

• Write namespace abbreviations so that ObsPy can read the written StationXML files again with the other namespaces.

• More conservative merging of stations. Stations are now only merged if everything except start and end date and the channels are the same. Otherwise they are not merged and will be retained. See #61. This might result in some slightly larger StationXML files in the ASDF files but should make no difference for downstream tools so it should affect users.

• pytest is no longer a runtime dependency.

• Drop support for Python <= 3.6.
• Fix a few deprecations warnings in Python >= 3.7.
• flake8 and pytest no longer are runtime dependencies.
• Get rid of the special warnings handler as it interferes with other packages.

• Restore the ability to run tests with python -m pyasdf.tests.

• Implement ASDF version 1.0.3 which allows a bit more flexibility regarding names of auxiliary data sets as well as provenance files.
• New .waveform_tags property for the dataset object return a set of all available waveform tags (see #46, #47)

• Support for ASDF version 1.0.2. Allows writing traces that are less than one second short (see #44, #45).
• New get_waveform_attributes() method to quickly get all attributes for the waveforms of a stations (see #38, #39).

• Support for ASDF 1.0.1 (the only difference to 1.0.0 is support for 16 bit integer waveform data).

• Don't attempt to write ASDF header info to files in read-only mode.
• get_coordinates() now works for StationXML files with a very large number of comments.
• Station.getattr() now works with underscores or dots as the network and station separator.
• contains() implemented for the station accessor object.

• New script to convert a folder of SAC files to ASDF.

• More visible warnings on Python 2 if necessary.

• Now also works with Python 3 under windows.

• Also shipping license file.

• Stable, tagged version.
