Not sure which are really worth mentioning and public ones are already in NEWS. * compile optimized case dispatch for all special constant literals (Aaron Patterson) https://bugs.ruby-lang.org/issues/11769 * Fiddle::Function#call releases the GVL https://bugs.ruby-lang.org/issues/11607 (Just added to NEWS) * All non-blocking IO and socket methods allow `exception: false' https://bugs.ruby-lang.org/issues/10532 https://bugs.ruby-lang.org/issues/11229 ...and reduced calling overhead of these methods: https://bugs.ruby-lang.org/issues/11339 (Already in NEWS) * Socket#recv* methods allow a destination buffer to reduce GC pressure https://bugs.ruby-lang.org/issues/11242 (Already in NEWS) * stdlib updated to use exception-free non-blocking I/O https://bugs.ruby-lang.org/issues/11044 * (Linux-only) waiting on a single FD anywhere in the stdlib no longer uses select(2), making it immune to slowdowns with high-numbered FDs https://bugs.ruby-lang.org/issues/11081 https://bugs.ruby-lang.org/issues/11377 * speedup big structs (Yura Sokolov) https://bugs.ruby-lang.org/issues/10585 * memory reductions for instance variables in non-pure-Ruby classes (T_DATA, T_FILE, etc...) https://bugs.ruby-lang.org/issues/11170 * speed up Set#include? (Ismael Abreu) https://bugs.ruby-lang.org/issues/10754 Improvements by a thousand cuts, maybe :)
