This is an beta version. Some details may change in the final version.

An updated reference manual is included and also available at
        http://www.lua.org/work/doc

The complete diffs from alpha to beta-rc1 are available at
        http://www.lua.org/work/diffs-lua-5.4.0-alpha-beta-rc1.html
        http://www.lua.org/work/diffu-lua-5.4.0-alpha-beta-rc1.html

A test suite is available at
        http://www.lua.org/work/lua-5.4.0-beta-tests.tar.gz

If your platform is a common Unix-like platform, just do
        make guess
The Makefile will guess your platform using uname and build Lua for it.
We welcome feedback on this, which is new, especially more uname targets
with explicit rules and fixes for existing ones.

We also welcome feedback on the listings output by luac -l -l, because
luac has been rewritten to account for the new VM instructions.

All feedback welcome. Thanks.

find in attachment some fixes for minor issues (found with a linter).
