Ruby 1.9.3 is the latest stable version of Ruby, with major increases in speed and reliability. With this major update from Ruby 1.8.7 in Fedora 16 to Ruby 1.9.3 in Fedora 17, alongside JRuby, Fedora becomes the superior Ruby development platform.

Ruby 1.9.3 is upstream's new major release of Ruby. The MRI reference interpreter is replaced by the YARV bytecode interpreter, designed to greatly improve the execution time of ruby programs. 
In doing so, upstream has set the anticipations for downstream consumers with faster and more reliable Ruby. Bringing Ruby 1.9.3 to Fedora is essential for Fedora to be at the top of it's game as a Ruby development platform.
Benefit to Fedora
Supporting the growth of a young language with a performance-enhancing milestone release. Add to that the multiplatform targetted development we enable downstream parties to do using our distribution.
The following includes a summary of changes included in this feature:
- New Packaging Guidelines for Ruby packages (gems and extension libraries)
- Rebuilding of all Ruby packages, and all packages depending on Ruby
- Changes to the search path to comply with the multi-versioning
- Changes to the location of files to comply with FHS, multilib and packaging standards
New Packaging Guidelines
Drafts of new packaging guidelines will have to be proposed to FPSCo. No such drafts currently exist.
Ruby Search path
The ruby search path is going to change. Not set in stone yet, but this is what it is right now:
$ ruby -e "puts $:" /usr/local/lib64/ruby/site_ruby /usr/local/share/ruby/site_ruby /usr/lib64/ruby/vendor_ruby /usr/share/ruby/vendor_ruby /usr/lib64/ruby /usr/lib64/ruby/x86_64-linux
Changes like these mean that the Packaging Guidelines for Ruby will also need to be updated.
Packages that require "ruby(abi) = 1.8"
Requires rebuilding numerous packages that depend on ruby(abi) = 1.8, or have Requires or BuildRequires for package dependent on ruby(abi) = 1.8. All these packages has to be updated to support ruby(abi) = 1.9
- 115 in total
repoquery --repoid=rawhide-source --arch=src --whatrequires 'ruby(abi) = 1.8' | sort | uniq
Packages that require "*ruby*"
- 334 in total (115 matches from previous query, of course)
repoquery --repoid=rawhide-source --arch=src --whatrequires '*ruby*' | sort | uniq
