2019-10-15 version 1.3.1

Enhancements / Changes:

• RtMidi C++ exceptions are now caught when creating RtMidiIn/Out instances and converted into a Python rtmidi.SystemError exception.
• Helper functions in rtmidi.midiutil now raise sub-classes of rtmidi.RtMidiError wherever appropriate. The docstrings where updated accordingly.
• Updated rtmidi sub-module, which includes the following changes:
  • C++ exceptions, when thrown, do not print the error message to stderr anymore.
  • When the JACK backend can't be initialized (e.g. when the server isn't running) it causes a DRIVER_ERROR instead of just a printing a WARNING.

Examples:

• midiout.py: removed surplus second argument to open_midioutput left over from previous version of script.
• Renamed example script midiwrapper.py to midioutwrapper.py to better indicate its function.
• sendsysex.py: use helper functions from midiutil module to list and open MIDI ports; improve error handling.
• Made sure MIDI ports are always properly closed and MidiIn/Out instances are deleted.
• Inserted delay before closing/deleting output (may be needed with Windows MMS).
• Simplified command line argument handling.
• Fixed example script file names in header comments.

Documentation:

• Made various small documentation wording changes and typo fixes.
• Updated year in copyright info in license file and Sphinx documentation.

Project infrastructure:

• Updated development dependency on urllib3 to 1.24.2 (CVE-2019-11324).

2019-04-15 version 1.3.0

Enhancements / Changes:

• Added get_api_display_name module-level function.
• Added get_api_name module-level function.
• Added get_compiled_api_by_name module-level function.
• Updated rtmidi sub-module to include all changes from upstream up to commit 791dfea.

Documentation:

• Improved installation instructions and listed options recognized by setup.py.

2019-01-18 version 1.2.1

Fixes:

• Fixed build when compiling with JACK support, but JACK version is too old to have jack_port_rename function (#40).

Project infrastructure:

• Added Linux builds for Python 2.7 and 3.4 - 3.7 to Travis CI setup.

2019-01-13 version 1.2.0

Project infrastructure:

• RtMidi Sources and header are now included as a git sub-module from the 'python-rtmidi' branch of a fork of the upstream RtMidi repository. This fork incorporates changes and fixes by pull requests to the upstream repository, which are (yet) unmerged, and some changes specific to python-rtmidi.

Enhancements / Changes:

• Added get_rtmidi_version module-level function.
• Added set_client_name and set_port_name methods to MidiIn's and MidiOut's base class.
• Added a bunch of new custom exceptions, all derived from RtMidiError.
• A default error handler callback is now set for MidiIn and MidiOut instances, which maps C++ level errors into custom Python exceptions.

Examples:

• Enhanced example script midiwrapper.py with methods for more MIDI messages, including sending all kinds of controller change and of (N)RPN messages.

Fixes:

• Fixed SysEx message reception in JACK backend in RtMidi: messages broken up over several events are now collected into a single event before being passed to the input callback or returned by MidiIn.get_message.
• Fixed missing MIDI message input filtering in JACK backend in RtMidi: MidiIn.ignoreTypes now works as intended.

Testing:

• Restructured tests in test_rtmidi and added tests for new methods.

2018-10-10 version 1.1.2

Project infrastructure:

  Thanks to Benoit Pierre for the PR (#36).

• Upload Gzip'ed instead Bzip'ed tarballs for source distributions to PyPI.

• python setup.py test now runs tox, so tests_require in setup.py is empty now. We want dependencies to be only handled by pip, never by setuptools.
