+ User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07):
+ 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:
+x 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:
+-bit and 32-bit memory acces: UW@ UL@ SW@ SK@ W! L! W@ L@ /W /L
+   FTRUNC FMOD (undocumented)
+   NEXT-ARG SHIFT-ARGS (OS command-line argument processing)
+ 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 K1 K2 K3 K4 K5 K6 K7 K8 K9 K10 K11 K12
+     S-K1 S-K2 S-K3 S-K4 S-K5 S-K6 S-K7 S-K8 S-K9 S-K10 S-K11 S-K12
+   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)
+   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)
+  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.
  User-visible changes between 0.6.0 and 0.6.1:
  Bug fixes (installation on big-endian machines sometimes did not work)
