2.1.0 Release Candidate 1
RubyGems 2.1.0 will contain new features. To update to RubyGems 2.1.0.rc.1 run:
gem update --system --prerelease
To downgrade to RubyGems 2.0.6 run:
gem update --system=2.0.6
If you need further instructions for downgrading RubyGems after installing 2.1.0.rc.1 see the upgrading documentation.
- RubyGems uses a new dependency resolver for gem installation which works similar to the bundler resolver. The new resolver can resolve conflicts the previous resolver could not and offers improved diagnostics when conflicts are discovered.
- RubyGems now has improved platform matching for the ARM architecture. Gems built with a CPU of “arm” will match any specific ARM CPU. See
gem help platformfor further details. Fixes #532 by Kim Burgestrand.
The –version option now accepts compound requirements the same as in a gem dependency. The following invocation will install rails between 4.0.0.beta and 4.2:
gem install rails -v '>= 4.0.0.beta, < 4.2'

makeenvironment variables over rbconfig.rb’s make if present. Pull Request #443 by Erik Hollensbe

- When a –version option with a prerelease version is given RubyGems automatically enables prerelease versions but only the last version is used. If the first version is a prerelease version this is no longer sticky unless an explicit
--no-prereleasewas also given. Fixes part of #531.

- RubyGems now suggests how to fix permission errors. Pull request #553 by Odin Dutton.

gem pristine --all --only-executables --env-shebang(or
--no-env-shebang). Issue #579 by Paul Annesley.

gem uninstallwhich removes all gems in GEM_HOME. Pull request #584 by Shannon Skipper.
- Added Gem.find_latest_files which is equivalent to Gem.find_files but only returns matching files from the latest version of each gem. Issue #186 by Ryan Davis.
- Improved performance of
gem outdatedby reducing duplicate work (it is still slow, but I see a near 50% improvement for 250 gems on a fast connection). See also Gem::Specification::outdated_and_latest_version
- rubygems_plugin.rb files are now only loaded from the latest installed gem.
- Altered use of cryptography in the test suite to work on JRuby, but some tests still fail on JRuby. Bug #606 by Hemant Kumar.
