v1.23.0

Changelog

Announcements

• Keep your eye on the ball.

Improvements

• Compilation routines used in peephole optimization now are considered "applicable" only
  if they strictly improve program fidelity (@notmgsk, #684).
• Fidelities greater-than-or-equal-to 1.0 are now truncated to (1 - double-float-epsilon)
  rather than 0.999. Previously any fidelity greater than 0.999 was truncated to 0.999
  which might cause confusion if a gate with better fidelity (e.g. 0.9999) is dropped in
  favor of a gate with poorer fidelity (e.g. 0.999) because both would be seen to have
  fidelity 0.999 after being truncated (@notmgsk, #683).
• eye uses the default magicl type (@kilimanjaro, #681).
• XY chips can be built using the standard constructors (@notmgsk, #680).
• Allow post-loading of ASDF systems (@colescott, #672).
• Find matrices for your exotic gate set with SOLVE-FOR-ANSATZ-INPUTS (@stylewarning,
  #670).

Bug fixes

• Call PRINT-OBJECT directly on compiler output gates (@notmgsk, #679).
