RubyGems 0.9.4.6 is a beta release for the upcoming 0.9.5 which adds  
several new features and fixes several bugs.

To upgrade to the beta:

   gem update --system --source http://segment7.net/

A tar.gz and .zip of the beta can also be downloaded for manual  
installation:

   http://segment7.net/temp/rubygems-0.9.4.6.tgz
   http://segment7.net/temp/rubygems-0.9.4.6.zip

Unpack either and run `ruby setup.rb`.

To file bugs:

http://rubyforge.org/tracker/?func=add&group_id=126&atid=575

When filing a bug, `gem env` output will be helpful in diagnosing the  
issue.

If you find a bug where RubyGems crashes, please provide debug  
output.  You can do that with `gem --debug the_command`.  For example:

$ gem --debug unknown_command
Exception `RuntimeError' at [...]/rubygems/command_manager.rb:114 -  
Unknown command unknown_command
ERROR:  While executing gem ... (RuntimeError)
     Unknown command unknown_command
         [...]/rubygems/command_manager.rb:114:in `find_command'
         [...]/rubygems/command_manager.rb:103:in `process_args'
         [...]/rubygems/command_manager.rb:74:in `run'
         [...]/rubygems/gem_runner.rb:39:in `run'
         /usr/local/bin/gem:22

== Changes Since 0.9.4.5

* `gem update` won't install gems multiple times (due to dependencies)
* `gem.bat` and bin stubs on mswin platforms are improved and compatible
   with the One-Click Installer
* `gem install` no longer installs dependencies for old versions of a  
gem
* Removed gem* commands are now replaced with stubs that warn
* RubyGems now installs correctly with RUBYOPT=-rubygems
