LuaTeX 1.0.0
It's interesting to see the trajectory of Lua adoption. The determining factor of the popularity of most languages was at the fate of large companies, (AT&T/C, Netscape/JavaScript, Microsoft/C++, Google/Python). On the flip side, Lua seems to slowly gain more and more popularity over the years. It's more "organic", for lack of a better term.<p>I really hope a big company doesn't pick Lua up, because I think the fact that it hasn't reached "Eternal September" yet is what makes it such a good language. It has room to breathe.<p>(The fact that it's beginner friendly, has an ANSI C89 implementation, and has the best/fastest JIT/FFI doesn't hurt either though :P)
