Updated NEWS files to 2006-05-07
minor documentation changes

    1: User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07):
    2: 
    3: variable THREADED-CODE-POINTER-TYPE for parameterizing Inst ** (undocumented)
    4: Better support for explicit stack access (see documentation) (works with static superinsts?)
    5: support for static multi-state stack caching (undocumented)
    6: 
    7: 
    8: User-visible changes between 0.6.[01] and 0.6.2:
    9: 
   10: You now have to define a macro MAYBE_UNUSED (see manual); useful for
   11:   suppressing expected "unused variable" warnings.
   12: 
   13: User-visible changes between 0.5.9-20020901 and 0.6.0:
   14: 
   15: Support for upward-growing stacks (see "Stack growth direction" in the
   16:   manual)
   17: New macro in output: IMM_ARG.
   18: New input flag: include-skipped-insts (currently pointless).
   19: Lazy loading and eager storing of stack items in superinstructiuons;
   20:   this reduces register pressure (useful on 386), but causes compiler
   21:   warnings about unused variables.
   22: 
   23: 
   24: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
   25: 
   26: The store optimization is now disabled by default, but can be enabled
   27: by the user.  Documentation for this optimization is also new.
   28: 
   29: 
   30: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
   31: 
   32: There is now a manual (in info, HTML, Postscript, or plain text format).
   33: 
   34: There is the vmgen-ex2 variant of the vmgen-ex example; the new
   35: variant uses a union type instead of lots of casting.
   36: 
   37: Both variants of the example can now be compiled with an ANSI C
   38: compiler (using switch dispatch and losing quite a bit of
   39: performance); tested with lcc.
   40: 
   41: There are several changes in the way you have to define macros (see
   42: node/section "Changes" in the manual).  I recommend keeping the
   43: gforth-0.5.9-20010501 version until you have completed the changes
   44: (note that you can have several versions of Gforth installed at the
   45: same time).
