- In multi-user environments, it is common to supply mulitple versions of gems
(for example Rails), allowing individual users to select the version of the
gem they desire. This allows a user to be insulated from updates to that
gem. RubyGems 0.8.10 fixes a problem where gems could occasionally become
confused about the current versions of libraries selected by the user.
- The other annoying bug is that if there are any existing rubygems-update gems
installed, then the “gem update –system” command will download a new
update, but install the latest update prior to the download.
