Changes: You can read Ruby's own announcement here: = What's new in Ruby, for Windows users? Ruby's announcement was generic in relation to all the new features added to the language. However, it missed enhancements specific to our platform of choice. * Enhancements: * Faster startup due improved Windows-specific API. [Bug #6836] * Support ANSI-colors out of the box without the need of external tools or gems. [Feature #6418] * Fixes for native 64bits builds for Windows under MinGW = What's new in RubyInstaller? Beyond what is covered by Ruby itself, we have our own set of improvements: * Enhancements: * Upgraded Ruby 2.0.0 to patchlevel 195 * Upgraded OpenSSL to version 1.0.0k * Upgraded rb-readline to 0.5.0.pre.1 (compatible with Ruby 2.0) * Bugfixes: * Generate documentation for target version of Ruby = Important Notes * Ruby 2.0.0-p195 is brand new While officially 2.0.0 is stable, that doesn't mean all the software will magically work on it. Use 2.0.0 for development and verify your application, scripts and tools works properly before deciding to run this in your production environment. * Existing pre-compiled gems are not Ruby 2.0 compatible Ruby 2.0 introduces ABI breakage which means compiled C extensions with previous 1.9.3 will work with Ruby 2.0. DO NOT install Ruby 2.0 on top of existing Ruby 1.9.3, or try to use compiled extensions with it. You will be required to force compilation of those gems: gem install <name> --platform=ruby This will require you have the extra dependencies required for that gem to compile. Look at the gem documentation for the requirements. * Do not use other DevKit version than the one recommended This version of Ruby has been compiled and optimized for mingw-w64 GCC 4.7.2. Use of older version of DevKit package to compile gems might result in compilation issues during gem installation or simply segfaults. Look for the DevKit installers identified with the name 'DevKit-mingw64-32' and 'DevKit-mingw64-64' for 32 and 64 bits respectively. = Alternate download links Sometimes RubyForge might have issues when trying to download the above files.
