Lua 4.0.1 is now available for download at
http://www.lua.org/ftp/lua-4.0.1.tar.gz
This is a full distribution which merges the modules in lua-4.0-update
into
the original Lua 4.0 code. Only those modules have been touched. (A
complete
list of updated modules is in UPDATE; diffs from the original code are
in
DIFFS.) READMEs and other documentation still refer to Lua 4.0 (and
this is
ok, since 4.0.1 is simply a bug-fix release). However, LUA_VERSION in
lua.h
has been changed to 4.0.1 so that you know what you're running.
Lua 4.0.1 is now officially the current Lua version.
