• Fixed some regressions in the formatter

0.14.0 (2016-03-21)

• (breaking change) The syntax of a method argument with a default value and a type restriction is now def foo(arg : Type = default_value). Run crystal tool format to automatically upgrade exsiting code to this new syntax. The old def foo(arg = default_value : Type) was removed.
• (breaking change) Enumerable#take(n) and Iterator#take(n) were renamed to first(n)
• (breaking change) Socket#addr and Socket#peeraddr were renamed to local_address and remote_address respectively
• (breaking change) Removed Comparable#between?(a, z). Use a <= x <= z instead
• (breaking change) HTTP::WebSocketHandler callbacks can now access the HTTP::Context. If you had a forwarding method to it you'll need to update it. See #2313.
