You're mixing up things! TeX is a set of a few binaries, some of them are the
TeX engines (pdfTeX, XeTeX, LuaTeX, conTeXt). The majority of the TeX software
are text files. If a change in a library is breaking the TeX engine, then the
change itself is faulty. If you're using a TeX function (library call) of a
future version of that software, then something has to fail. If you're using an
old function (library call) that has been changed, then you can't assume
something useful will happen to come out.
