Non-news: No changes between 0.7.0 and 1.0:

While there has been advances in the techniques used in Gforth, we
have not documented or in any other way made them approachable for
Vmgen users.  This is also due to the question how many there are, and
what features you would be interested in.

The examples have seen small changes to adapt them to current
toolchains.

User-visible changes between 0.6.2 and 0.7.0:

Bugfixes (in particular a Gforth bug when dealing with "../" is fixed).

Vmgen by default behaves just as in 0.6.2.  While some advances have
  been implemented, the result is not mature enough for general
  consumption and is therefore disabled by default.


User-visible changes between 0.6.[01] and 0.6.2:

You now have to define a macro MAYBE_UNUSED (see manual); useful for
  suppressing expected "unused variable" warnings.

User-visible changes between 0.5.9-20020901 and 0.6.0:

Support for upward-growing stacks (see "Stack growth direction" in the
  manual)
New macro in output: IMM_ARG.
New input flag: include-skipped-insts (currently pointless).
Lazy loading and eager storing of stack items in superinstructiuons;
  this reduces register pressure (useful on 386), but causes compiler
  warnings about unused variables.


User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:

The store optimization is now disabled by default, but can be enabled
by the user.  Documentation for this optimization is also new.


Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:

There is now a manual (in info, HTML, Postscript, or plain text format).

There is the vmgen-ex2 variant of the vmgen-ex example; the new
variant uses a union type instead of lots of casting.

Both variants of the example can now be compiled with an ANSI C
compiler (using switch dispatch and losing quite a bit of
performance); tested with lcc.

There are several changes in the way you have to define macros (see
node/section "Changes" in the manual).  I recommend keeping the
gforth-0.5.9-20010501 version until you have completed the changes
(note that you can have several versions of Gforth installed at the
same time).
