Release 1.3.0

• Pattern match now check arity of pattern and block
• PatternMatching::ALL pattern now should be presented as variable length args (*args)
• NoMethodError and ArgumentError raised from method block won't be catched anymore by lib

Release 1.2.0

• Record classes can be declared with a type/protocol specification for type safety.
• Improved documentation
• Improved tests
• Better synchronization (thread safety) on all platforms
• Continuous integration run on both Linux (Travis CI) and Windows (AppVeyor)

Release 1.1.0

• A simple implementation of tuple, an
  immutable, fixed-length list/array/vector-like data structure.
• FinalStruct, a variation on Ruby's OpenStruct in which all fields are "final" (meaning
  that new fields can be arbitrarily added but once set each field becomes immutable).
• FinalVar, a thread safe object that holds a single value and is "final" (meaning
  that the value can be set at most once after which it becomes immutable).

Release 1.0.0

Version 1.0 is a complete rewrite. Previous versions lacked a unified focus. Version 1.0 is a cohesive set of utilities inspired by other languages but designed to work together in ways idiomatic to Ruby.

Complete API documentation can be found at Rubydoc.info.
