TBA – Yukihiro 'Matz' Matsumoto
summary
Ruby 2.0 ships on Feb 24 2013, claims to be faster than 1.9 and largely compatible while fixing many bugs; it introduces keyword arguments, Module#prepend for method decoration, lazy Enumerables, symbol-array literals and to_h/to_str conversions, and sets UTF-8 by default. Garbage collection gets copy/write–friendly marking and plans for partial generational GC; refinements land but remain experimental. Require/load performance and release cadence move toward yearly updates; the language marks its 20th anniversary and urges migration from 1.8/1.9.
