Ruby 2.2.0-preview1 Released
// Ruby News

We are pleased to announce the release of Ruby 2.2.0-preview1.

Ruby 2.2.0-preview1 is the first preview of Ruby 2.2.0. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby.

For example, Symbol GC makes Symbols garbage collectable. This reduces memory usage of Symbols; because GC couldn't collect Symbols before Ruby 2.2. So Rails 5.0 will require Symbol GC. It will support only Ruby 2.2 or later. (See Rails' blog post for detail.)

Also, new Incremental GC decreases pause time of garbage collection. It is helpful to run Rails applications.

Enjoy programming with Ruby 2.2.0-preview1!
