   User-visible changes between 0.6.2 and 0.6.9 (up to 2007-09-12):
   
   Installation:
     support for DESTDIR, POST_INSTALL, INSTALL_SCRIPT
     report performance and functionality problems at end of "make"  
   Bug fixes
     Now works with address-space randomization.
     The single-step debugger works again in some engines.
     Many others.
   Ports:
     AMD64, ARM, IA-64 (Itanium): better performance
     PPC: disassembler and assembler (32-bit)
     Gforth EC: R8C, Lego NXT (complete?)
   Invocation:
     New flags --ignore-async-signals, --vm-commit (default overcommit)

     X:ekeys: new: EKEY>FKEY K-SHIFT-MASK K-CTRL-MASK K-ALT-MASK K-F1...K-F12
   Unicode support (incomplete, documentation probably not up-to-date):
     added xchars words for dealing with variable-width multi-byte characters
     provide 8bit (ISO Latin 1) and UTF-8 support for xchars
   Number prefixes:
     0x is a hex prefix: 0xff and 0XfF now produces (decimal) 255
     # is a decimal prefix: #10 now produces (decimal) 10
     Signs after the number prefix are now accepted, e.g, #-50.
     ' now only handles a single (x)char: 'ab is no longer accepted, 
                                          'a' now produces (decimal) 97
   New words:
     \C C-FUNCTION (libcc C interface)
     OUTFILE-EXECUTE INFILE-EXECUTE BASE-EXECUTE (limited change of global state)

     NEXT-ARG SHIFT-ARGS (OS command-line argument processing)
     NOTHROW (for backtrace control)
     FTRUNC FMOD (undocumented)
     SEE-CODE SEE-CODE-RANGE (show generated dynamic native code)
   Improvements/changes of existing words:
     S\", .\" now support \l, \m, \z, and limits hex and octal character specs.
     OPEN-FILE with W/O no longer creates or truncates files (no compat. file)
     TRY...ENDTRY changed significantly, compatibility files available (see docs).
     The disassembler (DISCODE) can now use gdb to disassemble code
     Uninitialized defered words now give a warning when executed
     Division is floored (disable with "configure --enable-force-cdiv")
     Gforth (not gforth-fast) reports division by zero and overflow on division
       on all platforms.
   Newly documented words:
     S>NUMBER? S>UNUMBER?
     EKEY keypress names: K-LEFT  K-RIGHT K-UP K-DOWN K-HOME K-END K-PRIOR
       K-NEXT K-INSERT K-DELETE
     CLEARSTACKS
     FORM
   Environment variable GFORTHSYSTEMPREFIX (used by word SYSTEM and friends)
   C interface:
     exported symbols now start with "gforth_" (for referencing them from C code)
     support for use of libffi (supplied with gcc) (undocumented) and
     a C-compiler-based approach (requires C compiler at run-time) (incomplete).
   Libraries:
     depth-changes.fs: report stack depth changes during interpretation
     ans-report.fs now reports CfV extensions
     fsl-util.4th: FSL support files (undocumented)
     regexp.fs for regular expressions (undocumented)
     complex.fs for complex numbers (undocumented)
     fft.fs for Fast Fourier Transform (undocumented)
     wf.fs, a Wiki implementation (undocumented)
     httpd.fs, a web server (undocumented)
     status.fs, show interpreter status in separate xterm (undocumented)
     profile.fs for profiling (undocumented, incomplete)
     endtry-iferror.fs, recover-endtry.fs to ease the TRY change transition
     test/tester.fs: Now works with FP numbers (undocumented)
     test/ttester.fs: Version of tester.fs with improved interface (T{...}T).
    compat library:
     compat/execute-parsing.fs
   Speed improvements:
     static stack caching (good speedup on PPC)
     mixed-precision division is now faster
     support for int128 types on AMD64
     workarounds for gcc performance bugs (in particular, PR 15242)
     branch target alignment (good speedup on Alpha).
   
   
   User-visible changes between 0.6.1 and 0.6.2:
   
   Bug fixes (in particular, gforth-0.6.2 compiles with gcc-3.3)
   New words: LATEST, LATESTXT (LASTXT deprecated)
   Operating environment: Added optional support for a C interface built
     on the ffcall libraries (more portable and powerful than the old
     one, but still not documented).  To use it, the ffcall libraries
     have to be installed before building Gforth (see INSTALL).
   Miscellaneous: Gforth-fast now uses static superinstructions (some
     speedup on some platforms); generally this is transparent (apart
     from the speedup), but there are lots of command-line options for
     controlling the static superinstruction generation.
   
   
   User-visible changes between 0.6.0 and 0.6.1:
   
   Bug fixes (installation on big-endian machines sometimes did not work)
   
   
 User-visible changes between 0.5.0 and 0.6.0:  User-visible changes between 0.5.0 and 0.6.0:
   
 added words: EDIT-LINE ID. .ID CONST-DOES> K-PRIOR K-NEXT K-DELETE SLURP-FILE SLURP-FID WORDLIST-WORDS  Changes in behaviour:
   
   S": interpreted use now ALLOCATEs the string (they live until BYE).
 Long word names (512MB on 32-bit systems) are now supported (change to  Long word names (512MB on 32-bit systems) are now supported (change to
   the header format).    the header format).
   New threaded code execution method: primitive-centric (allows the
     following), hybrid direct/indirect threaded (easier portability),
     with dynamic superinstructions (typical speedup on Athlon: factor
     2).  New engine gforth-itc for dealing with some potential
     backwards-compatibility problems (see "Direct or Indirect Threaded?"
     in the manual).
   
   Operating environment:
   
   Default dictionary size is now 4MB.
   Large file support on OSs that support them (i.e., files with more
     than 2GB on 32-bit machines).
   Gforth can now deal well with broken pipes in most situations.
   vi tags files can be built with tags.fs (usage like etags.fs).
   gforth.el mostly rewritten.
   New image file format.
   
   New words:
   
   Keyboard input: EDIT-LINE K-PRIOR K-NEXT K-DELETE
   File input: SLURP-FILE SLURP-FID 
   Programming tools: ID. .ID WORDLIST-WORDS SIMPLE-SEE
   Conditional execution: [DEFINED] [UNDEFINED]
   Defining Words: CONST-DOES> ]]
   Input stream: PARSE-WORD EXECUTE-PARSING EXECUTE-PARSING-FILE
   String comparison: STR= STR< STRING-PREFIX?
   String literals: S\" .\" \"-PARSE
   Floating point output: F.RDP F>STR-RDP F>BUF-RDP
   
   Miscellaneous:
   
 Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the  Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the
   new capabilities in prims (e.g., automatic handling of the return    new capabilities in prims (e.g., automatic handling of the return
   stack and instruction stream).    stack and instruction stream).
   
 New threaded code execution method: primitive-centric (allows the  
   following), hybrid direct/indirect threaded (easier portability),  
   with dynamic superinstructions (typical speedup on Athlon: factor  
   2).  New engine gforth-itc for dealing with some  
   backwards-compatibility problems (see "Invoking Gforth" in the  
   manual).
