Today, Feb. 24th, is the 21st anniversary of Ruby, so we happily announce a new patch release of Ruby 2.1, Ruby 2.1.1.

Ruby 2.1 has many improvements including speedup without severe incompatibilities. You can use this on Rails and other applications, and get a more comfortable experience.

This release includes many bugfixes. See tickets and ChangeLog for details.

Following the previously announced changed versioning policy of Ruby 2.1, this version is simply called “2.1.1”.

Update: We’ve noticed a regression in Hash#reject . For more details, see: Regression of Hash#reject in Ruby 2.1.1.
