I added the following to Jonesforth:
  tail-call optimization; DOVAR/DOCON -> simplified CONSTANT/VARIABLE/VALUE; 
  FIG-FORTH-style CREATE ... DOES> support; case-insensitive FIND; pentium
  optimizations; SEE aborts on word not found; constant, variable and DOES>
  decompilation (and indicate primitives).  Also added optional space-saving 
  DOES> support, which cannot be decompiled and is probably slower.
