I knew that in general but thank you for the details.

Probably I wasn't too clear, but I meant that what you just said is not 
stated in the manual or in any readily available "specification" (a page 
in Lua site, a technical note or such) stating that clearly.

You have to search the archives or the WIKI, here and there, to find 
out. Or am I mistaken?

For example on the versions page (www.lua.org/versions.html) there is no 
hint to the release number (maybe what you just said could be inserted 
in a note in that page under a "version numbering scheme" section).
