 User-visible changes between 0.5.0 and 0.6.0:

   SLURP-FILE SLURP-FID WORDLIST-WORDS SIMPLE-SEE [DEFINED] [UNDEFINED]  
   PARSE-WORD S\" .\" \"-PARSE STR= STR< STRING-PREFIX? EXECUTE-PARSING  
   EXECUTE-PARSING-FILE F.RDP F>STR-RDP F>BUF-RDP  
   
 Large file support on OSs that support them (i.e., files with more  User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07):
   than 2GB on 32-bit machines).  
   
 Default dictionary size is now 4MB.  Installation:
     support for DESTDIR, POST_INSTALL, INSTALL_SCRIPT
     report performance and functionality problems at end of "make"  
   Bug fixes
     Among others: now works with address-space randomization.
     The single-step debugger works again in some engines.
   Ports:
     AMD64, ARM, IA-64 (Itanium): better performance
     Gforth EC: R8C port
   Forth 200x:
     extension queries (produce true for all implemented extensions)
     REQUIRED etc. (not new)
     [DEFINED] and [UNDEFINED]
     PARSE-NAME (new name)
     deferred words (new: DEFER@ DEFER! ACTION-OF)
   Unicode support (incomplete):
     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
     ' now only handles a single (x)char: 'ab is no longer accepted, 
                                          'a' now produces (decimal) 97
   The disassembler (DISCODE, SEE <primitive>) can now use gdb to disassemble code
   Uninitialized defered words now give a warning when executed
   New words:
     16-bit and 32-bit memory acces: UW@ UL@ SW@ SK@ W! L! W@ L@ /W /L

     CLEARSTACKS
   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) and
     a C-compiler-based approach (requires C compiler at run-time) (incomplete).
   Libraries:
     depth-changes.fs: report stack depth changes during interpretation
     fsl-util.4th: FSL support files (undocumented)

     status.fs, show interpreter status in separate xterm (undocumented)
     profile.fs for profiling (undocumented, incomplete)
    compat library:
     compat/execute-parsing.fs
   Speed improvements:
     static stack caching (good speedup on PPC)
     fast mixed-precision division words on i386 and AMD64
     support for int128 types on AMD64
     workarounds for gcc performance bugs (in particular, PR 15242)
   
   
   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.
   
 vi tags files can be built with tags.fs (usage like etags.fs).  
   
 gforth.el mostly rewritten.  User-visible changes between 0.6.0 and 0.6.1:
   
 S": interpreted use now ALLOCATEs the string (they live until BYE).  Bug fixes (installation on big-endian machines sometimes did not work)
   
 Long word names (512MB on 32-bit systems) are now supported (change to  
   the header format).  
   
 Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the  User-visible changes between 0.5.0 and 0.6.0:
   new capabilities in prims (e.g., automatic handling of the return  
   stack and instruction stream).  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

   Operating environment:
   
   Default dictionary size is now 4MB.
   Large file support on OSs that support them (i.e., files with more

   Gforth can now deal well with broken pipes in most situations.

 New image file format.  New image file format.
   
   New words:
   
   Keyboard input: EDIT-LINE K-PRIOR K-NEXT K-DELETE
