Edit: just scrolled down further in the thread, and yes, it does break termux. I guess I'll be one of those people stuck on an old version for ever now. What a pain. Also, even if it gets fixed, things like cpan/pip/gem etc. will have issues. Apparently, you can't even compile something, and applications will now have to be distributed in huge collections (apks). Yay.
Edit 2: Some think that python/perl/ruby stuff will still work, but I know for a fact that some python modules are interfaces to c programs (numpy, scipy) and that many ruby modules are similar (remember nokogiri "building native extensions"?).
