[Stefan Westerfeld]

liquidsfz-0.2.2 has been released

The main goal of liquidsfz is to provide an SFZ sampler implementation
library that is easy to integrate into other projects. A standalone jack
client and a LV2 plugin is also available.

liquidsfz is implemented in C++ and licensed under the GNU LGPL version
2.1 or later. The release tarball can be downloaded here:

Overview of Changes in liquidsfz-0.2.2:
=======================================
* Implement filters (fil_type, cutoff, resonance, ...)
  - all SFZ1 filter types (lpf_1p, lpf_2p, hpf_1p...)
  - some SFZ2 filter types (lpf_4p, lpf_6p, hpf_4p, hpf_6p)
  - filter envelope (fileg_attack, fileg_depth, ...)
* Support midnam for LV2 to provide controller/key/switch information
* Key/Key Switch information:
  - API: provide key and key switch information (Synth::list_keys)
  - opcodes: implement key and keyswitch names (sw_label, label_keyN)
  - hydrogen loader: provide key names for each mapped key
  - add keys/switches/ccs command in liquidsfz jack client
* Improve key switch handling to fix problems with some sfzs #20
* Fix problems with clang++ using libc++ (for instance on macOS) #19
* Minor fixes and cleanups
