1: User-visible changes between 0.5.9-20020901 and 0.6.0:
2:
3: Support for upward-growing stacks (see "Stack growth direction" in the
4: manual)
5: New macro in output: IMM_ARG.
6: New input flag: include-skipped-insts (currently pointless).
7: Lazy loading and eager storing of stack items in superinstructiuons;
8: this reduces register pressure (useful on 386), but causes compiler
9: warnings about unused variables.

12: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
13:
14: The store optimization is now disabled by default, but can be enabled
15: by the user. Documentation for this optimization is also new.

17:
18: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
19:
20: There is now a manual (in info, HTML, Postscript, or plain text format).
21:
22: There is the vmgen-ex2 variant of the vmgen-ex example; the new
23: variant uses a union type instead of lots of casting.
24:
25: Both variants of the example can now be compiled with an ANSI C
26: compiler (using switch dispatch and losing quite a bit of
27: performance); tested with lcc.
28:
29: There are several changes in the way you have to define macros (see
30: node/section "Changes" in the manual). I recommend keeping the
31: gforth-0.5.9-20010501 version until you have completed the changes
32: (note that you can have several versions of Gforth installed at the
33: same time).
