   - (fixed) when opening audio input devices where the default
     device has insufficient channels (e.g., MacOS input is mono
     by default), logic has been added to also match sample rates
     when searching for alternate audio input devices;  additional
     logic added in the specific case of mono input devices to
     simulate stereo, to fulfill the standard request for stereo
   - (fixed) added check to prevent crash in rare situations involving
     self-join when deleting XThread in background. (git PR #103)
   - (fixed) by stuntgoat at github -- right-recursion in chuck parser
     can exhaust memory in larger chuck files; this has been updated
     to use left recursion.  (git PR #32, (finally) merged by hand by
     Spencer and Ge)  Also thanks to Tom Lieber for the initial analysis
     and solution:
   - (added) by Nathan Tindall -- Q and freq bounding for filters (LPF,
     HPF, BPF, BRF) to avoid LOUD FILTER EXPLOSIONS; now negative values
     will throw an exception on the offending shred.
   - (restored, macOS) MAUI Chugin now (re)supported, post
   - (added; developer) ChucK.h API to set a main thread hook (e.g., for
     graphical functionalitie from Chugins)
   - (updated, developer) Chugin API now support main thread callback
     for graphical-/GUI purposes
   - (developer) refactored code to move I/O-related code out of
     chuck_lang and into chuck_io.
