CMake target structure cleaned up: proper PUBLIC/PRIVATE dependencies, methcla::methcla alias target (#120)
Warning flags scoped per-target via methcla_target_warnings() (#120)

Methcla_Resource from plugin API: removed argument from Methcla_SynthDef::construct; renamed methcla_world_resource_retain/methcla_world_resource_release to methcla_world_synth_retain/methcla_world_synth_release
Dead platform code and unused vendored libraries (PNaCl, NaCl) (#127)
Dead code cleanup: Resource.hpp (deleted), DSP.h/DSP.c (deleted), ResourceIdAllocator renamed to IdAllocator with typedefs preserved (#148)
Vendored tinydir library; replaced with std::filesystem

Bus zeroing logic (#102)

Function for querying library version (methcla_version, Methcla::version())
Function for changing debug logging behaviour (methcla_engine_set_log_flags, Methcla::Engine::setLogFlags)
ExtAudioFile soundfile API (macOS)

Split synth creation into /synth/new (Methcla::Engine::synth) and /synth/activate (Methcla::Engine::activate)
Refactored engine interface: renamed Methcla::Engine::Request to Methcla::Request, removed Methcla::Engine::Bundle; Methcla::Request now has openBundle/closeBundle for nested bundle structures
Renamed Methcla::Engine::freeNode to Methcla::Engine::free
Moved plugin includes to <methcla/plugins/*>
