Hi
I discover now the test suite at
[...]
2) test suite version
From the web page:
"
If no test suite matches your release of Lua exactly,
download the suite for the closest Lua release of the same version.
Suites do not work across different versions."
The last suite is 5.3.4.
Can I use it with Lua 5.3.5 ?
Yes, since that is the same version (the version is identified by the first two numbers, and the third number indicate bugfix releases).
Can I use it with Lua 5.4.0 release candidate ?
No, since that is a different version. All 5.4 materials are currently available at
https://www.lua.org/work/. The current test suite is the lua-5.4.0-tests.tar.gz download (currently second from the top).
