Ruby 2.0.0

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

In Ruby, everything is an object. Every bit of information and code can be given their own properties and actions. Object-oriented programming calls properties by the name instance variables and actions are known as methods. Ruby’s pure object-oriented approach is most commonly demonstrated by a bit of code which applies an action to a number.

Change Log:

# New Features

- The UTF-8 default encoding, which make many magic comments omissible
* Built-in libraries
- Enumerable#lazy and Enumerator::Lazy, for (possibly infinite) lazy stream
- Enumerator#size and Range#size, for lazy size evaluation
- #to_h, which is a new convention for conversion to Hash
- Onigmo, which is a new regexp engine (a fork of Oniguruma)
- Asynchronous exception handling API
* Debug support
- DTrace support, which enables run-time diagnosis in production
- TracePoint, which is an improved tracing API
* Performance improvements
- GC optimization by bitmap marking
