  Line 1
+ 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).
+ Ports:
+ AIX.
+% speedup on 604e under powerpc-unknown-linux-gnu,
+%-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
+ Directory handling: OPEN-DIR READ-DIR CLOSE-DIR FILENAME-MATCH
+ Other: ]L PUSH-ORDER
+ Miscellaneous:
+ 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.
  User-visible changes between 0.3.0 and 0.4.0:
  Operating environment:
- Line 20  Direct threading now works on PowerPC (2
+ Line 80  Direct threading now works on PowerPC (2
  Better support for m68k (thanks to Andreas Schwab and Jorge Acereda).
  It is possible to create executables that contain the image (for
    non-OS systems).
- Added a lot of embedded control (EC) stuff.
+ Added a lot of embedded control (EC) stuff. Supported controllers and
+ small CPUs are Siemens C16x, 8086, 6502, Mixed-Mode's FPGA MISC, Bernd Paysan's
+stack processor. Not finished: ShBoom alias PSC1000, H8, AVR.
  New, changed, and removed words:
- Line 45  Reorganized files: added directories and
+ Line 108  Reorganized files: added directories and
    systems (but there are again some files that won't work there).
  Bug fixes.
  Various changes without log information only known as mega-patches.
+ Cross compiler now also supports compilation only for undefined or forward
+ referenced words. Plugins to support some native code generation
+ (for PSC1000).
  More files in the compat library.
