0.14.1

0.14.1 (2016-03-21)

• 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.
• New command crystal play that opens a playground for you to play in the browser :-) (thanks @bcardiff)
• New command crystal env that prints environment information
• Spec: you can now run multiple files with specified line numbers, as in crystal spec file1.cr:10 file2.cr:20 ...

• Added FileUtils.cp (thanks @Dreauw)
• Added Array#first(n) and Array#last(n) (thanks @greyblake)

• Added sync_close property to OpenSSL::SSL::Socket, Zlib::Inflate and Zlib::Deflate
• Added XML::Node#encoding and XML::Node#version
• Added HTTP::Client::Response#success? (thanks @marceloboeira)
• Added StaticArray#shuffle!(random) (thanks @Nesqwik)
• Added Splat#exp method in macros
• Added fiber-safe Mutex
• All Int types (except BigInt) can now be used in JSON and YAML mappings (thanks @marceloboeira)
• Instance variable declarations/initializations now correctly work in generic classes and modules
• Lots of bug fixes

0.13.0

• (breaking change) Matrix was moved to a separate shard: https://github.com/Exilor/matrix
• 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) syntax will be removed in a next release.

• run inside macros now also work with absolute paths (useful when used with __DIR__)
• Added docs for Math and StaticArray (thanks @zavydiel, @HeleneMyr)
• Many bug fixes and some micro-optimizations
