v0.2.0

Added

• Saving and loading instruments
• Comment field to instruments
• Ability to reorder tracks
• Add menu command to delete all unused data from song file
• Ability to search a unit by typing its name
• Ability to run sointu as a vsti plugin, inside vsti host
• Ability to lock delay relative to beat duration
• Ability to import 4klang patches (.4kp) and instruments (.4ki)
• The repository has example instruments, including all patches and
  instruments from 4klang
• The compiler templates are embedded in the sointu-compile, so no
  installation is needed beyond copying sointu-compile to PATH
• Ability to select multiple units and cut, copy & paste them
• Mousewheel adjusts unit parameters
• Tooltips to many buttons
• Support for gm.dls samples in the go-written virtual machine
• x86 and C written examples how to play a sointu song on various
  platforms. On Windows, the examples can optionally be linked with
  Crinkler to get Crinkler reports.

Fixed

• Unnamed instruments with multiple voices caused crashes
• In the native version, exceeding the 64 delaylines caused crashes
• wat2wasm nowadays uses funcref instead of anyfunc
• In the WebAssembly core, $WRK was messed after stereo oscillators,
  making modulations not work
• The Webassembly implementation of mono version of the "out" unit

Changed

• The release flag in the voice is now a sustain flag i.e. the logic has
  been inverted. This was done so that when the synth is initialized
  with zeros, all voices start with sustain = 0 i.e. in released state.
• The crush resolution is now in bits instead of linear range; this is a
  breaking change and changes the meaning of the resolution values. But
  now there are more usable values in the resolution.
