Ruby 2.0.0-p0 is the first stable release for Ruby 2.0, with a lot of new features and improvements. Ruby 2.0 is very compatible with 1.9, so it will be much easier to migrate to Ruby 2.0 (as compared to 1.8 to 1.9, read the official announcement).
What’s new in Ruby 2.0.0 ?
- core features (better API with keyword arguments, UTF-8 default encoding etc)
- Built-in libraries (Lazy Enumerator, Onigmo, Async exception handling API..)
- Debug Support (DTrace support)
- Performance improvements (GC optimization, faster require, VM optimization etc)
New to Ruby ?
Ruby is an easy to learn scripting language, similar to Python, Perl, PHP etc. It’s optimized for programmer’s happiness
