ktmidi 0.8.0 release

[atsushieno]

Today I have tagged ktmidi v0.8.0 and released the packages to Maven Central.

Note that there are some ABI-breaking changes in the overall API. Most of them happen in minor and/or untouched parts this time, unlike those in v0.7.0 and v0.6.0. Some git commits contain "BREAKING CHANGE" in their headline.

Here are the list of notable changes:

• In reflection to Android 15's new UMP support for MidiDeviceService (MidiUmpDeviceService), now we have UMP port support in MidiAccess. At abstraction layer there is midiTransportProtocol property on MidiPortDetails which will return 2 (MidiTransportProtocol.UMP) if it is a UMP port.
• We have native CoreMIDI support in ktmidi-native module: TraditionalCoreMidiAccess uses CoreMIDI API from MIDI 1.0 era, and UmpCoreMidiAccess uses modern CoreMIDI API that is available only after macOS 11 or iOS 14.
  • MIDI 2.0 support is totally untested. I need some MIDI 2.0 devices or whatever app as UMP CoreMIDI device. There does not seem any.
• New UmpDevice class and dev.atsushieno.ktmidi.umpdevice package: it handles all the UMP stream messaging complication and manages UMP Function Blocks, just like ktmidi-ci (new CIDevice class in v0.8.0) does for MIDI-CI. It will become easier to structure a virtual UMP port that contains multiple function blocks and have them work together.
• stateChanged event property in MidiAccess now takes StateChange enum argument and can really represent what kind of change has happened. CoreMidiAccess implementations above and and AndroidMidiAccess have implemented them (Android is untested yet, but our new API will be fine).
• A bunch of refactoring and restructuring on MIDI-CI API and implementation has been made, and the API is now way more intuitive than v0.7.0. MidiCIInitiator and MidiCIResponder are transformed into a single CIDevice class.
• Various minor MIDI-CI feature additions: MIDI 2.0 (UMP) support along with group support, JSONSchema resource, Profile Details and Profile Specific messages, etc.

AlsaMidiAccess will follow the UMP support way, once I get a stable installation setup for libasound-dev (whose embedded native shared library never worked fine in alsakt after all). Maybe around the time we have ubuntu-24.04 stable.

I have published v0.8.1 release today. Now we publish Apple arm64 packages as well as iOS packages to Maven Central too. https://repo1.maven.org/maven2/dev/atsushieno/

v0.8.1 (and v0.8.0) had some Maven packaging issue, so I ended up to fix it and publish as v0.8.2 (KMP with native builds is quite often cause of this kind of troubles). Code wise there is no change.
