Lua 5.4.0 (rc2) is now available for testing at
        http://www.lua.org/work/lua-5.4.0-rc2.tar.gz

The checksums are
        MD5     88b2ccda06903857ea738699c5dc3aa8  -
        SHA1    649b81a257af2fa0d83ff9035edb7c8c9f391ceb  -

This is the final version of Lua 5.4.0 (rc2).

The main changes in Lua 5.4.0 are listed at
        http://www.lua.org/work/doc/#changes

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

The complete diffs from rc1 to rc2 are available at
        http://www.lua.org/work/diffs-lua-5.4.0-rc1-rc2.html
        http://www.lua.org/work/diffu-lua-5.4.0-rc1-rc2.html

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

To build Lua in a common Unix-like platform, just do
        make
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).

François

the name of a function gives the address of this function,
so the & before the name is useless
