= Proposed System Wide Change: Ruby 2.3 = https://fedoraproject.org/wiki/Changes/Ruby_2.3 Change owner(s): * Vít Ondruch <vondruch AT redhat DOT com> Ruby 2.3 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.2 in Fedora 22 to Ruby 2.3 in Fedora 24, alongside JRuby, Fedora becomes the superior Ruby development platform. == Detailed Description == Ruby 2.3 is upstream's new major release of Ruby. Many new features and improvements are included. A Frozen String Literal Pragma is introduced. With Ruby 2.1, "str".freeze has been optimized to reduce object allocation. Ruby 2.3 introduces a new magic comment and command line option to freeze all string literals in the source files. Additionally for debugging, you can get where the object is created on "can't modify frozen String" error by --enable-frozen-string-literal-debug. A safe navigation operator, which already exists in C#, Groovy, and Swift, is introduced to ease nil handling as obj&.foo. Array#dig and Hash#dig are also added. The did_you_mean gem is bundled. The did_you_mean gem shows the candidates on the NameError and NoMethodError to ease debugging. Safe levels $SAFE=2 and $SAFE=3 are obsolete. == Scope == Proposal owners: * Finish packaging of Ruby 2.3. Current changes available in private-ruby-2.3 branch of ruby package in dist-git. * Rebuilding of Ruby packages providing native extensions (i.e. packages which depends on libruby). Other developers: * Rebuild of packages with binary extensions (i.e. packages which depends on libruby) will be handled automatically, but some packages might need fixes/updates to support Ruby 2.3 properly. Release engineering: * Separate Koji tag for package rebuild will be needed.
