As discussed the last few weeks during the EPEL weekly meeting, the rubygem-rack package will be updating in EPEL5. There are no current packages that depend on its current version (0.4), but there are several that require rack > 1.0.
rubygem-rack will be moving to version 1.1 in EPEL 5. This update will be available in epel-testing no later than tomorrow. This is not a 100% compatible ABI, it's very close but there are a few minor changes. Upon analysis of potential usage of rack, we felt this update was acceptable.
If there are no serious objections to moving the version of rack, it will placed in stable after the two-week period spent in epel-testing.
rubygem-rack version 1.1 should allow for usage with Sinatra, Padrino, Merb, many versions of Rails, and more.
Please let me know if you find any issues and offer karma to the update based upon your experiences with it.
