What changes will the next version bring?
No roadmap exists for Lua 5.2 yet. (But see this.) If you’re concerned with incompatibilities, you shouldn’t, because we make every effort to avoid introducing any incompatibilities. When incompatibilities are unavoidable, previous code is usually supported unmodified, possibly by building Lua with a suitable compilation flag. In any case, the reference manual contains a list of incompatibilities.
