Line 1 Line 1
   User-visible changes between 0.6.1 and 0.6.2:
   bugfixes (in particular, gforth-0.6.2 compiles with gcc-3.3)
   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:
   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
     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:
   File input: SLURP-FILE SLURP-FID 
   Programming tools: ID. .ID WORDLIST-WORDS SIMPLE-SEE
   Conditional execution: [DEFINED] [UNDEFINED]
   Defining Words: CONST-DOES> ]]
   String comparison: STR= STR< STRING-PREFIX?
   String literals: S\" .\" \"-PARSE
   Floating point output: F.RDP F>STR-RDP F>BUF-RDP
   Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the
     new capabilities in prims (e.g., automatic handling of the return
     stack and instruction stream).
   User-visible changes between 0.4.0 and 0.5.0:
   Changes in behaviour:
   There are now two engines: the fast engine (gforth-fast) is at least
     as fast as gforth in earlier releases; the debugging engine (gforth)
     supports precise backtracing for signals (e.g., illegal memory
     access), but is slower by a factor of 1-2.
   Block files now start at block 0 by default (instead of block 1).  If
     you have block files around, prepend 1024 bytes to convert them, or
     do a "1 OFFSET !" to establish the old behaviour.
   Gforth now does not translate newlines to LFs on reading.  Instead,
     READ-LINE now interprets LF, CR, and CRLF as newlines.  Newlines on
     output are in the OSs favourite format.
   SEE now disassembles primitives (or hex-DUMPs the code if no
     disassembler is available).
   >HEAD (aka >NAME) now returns 0 (instead of the nt of ???) on failure.
   Syntax of prim changed: stack effects are now surrounded by
     parentheses, tabs are insignificant.
   Operating environment:
   Gforth now produces a backtrace when catching an exception.
   On platforms supporting the Unix 98 SA_SIGINFO semantics, you get more
     precise error reports for SIGSEGV and SIGFPE (e.g., "stack
     underflow" instead of "Invalid memory address").
   Gforth now produces exit code 1 if there is an error (i.e., an
     uncaught THROW) in batch processing.
   You can use "gforthmi --application ..." to build an image that
     processes the whole command-line when invoked directly (instead of
     through gforth -i).
   20% speedup on 604e under powerpc-unknown-linux-gnu,
   19%-29% speedup on Celeron with gcc-2.95.
   New words:
   Missing ANS Forth words: EKEY EKEY? EKEY>CHAR
   Timing words: CPUTIME UTIME
   Vector arithmetic: V* FAXPY
   FP comparison: F~ABS F~REL
   Deferred words: <IS> [IS]
   Nested number output: <<# #>>
   Exception handling: TRY RECOVER ENDTRY
   Other: ]L PUSH-ORDER
   Significant extensions to the manual (added an introduction, among
     other things), many of them due to a new team member: Neal Crook.
   Added assemblers and disassemblers for 386, Alpha, MIPS (thanks to
     contributions by Andrew McKewan, Bernd Thallner, and Christian
     Pirker).  Contributions of assemblers and disassemblers for other
     architectures are welcome.
