RDoc 2.2.1 is available! It can be downloaded here or through the gem system. We are releasing RDoc again, so soon after the RDoc 2.2.0 release, in order to fix some bugs and include some community patches that were overlooked before the 2.2.0 release. These changes needed to be checked-in immediately as RDoc 2.2.1 will be part of the upcoming Ruby 1.9.1 release. This RDoc release includes a patch by Hugh Sasse that provides basic support for parsing Perl files for POD documentation. Additionally, ri will display the values of constants again, which has been broken for a few releases. Also, ri finally should resolve methods inherited from a parent class correctly (i.e., ri File.read). The (hopefully) last bug with this was in the documentation generation system, however, so a machine’s ri documentation will need to be rebuilt in order for this to work. The RubyGems documentation can be rebuilt by running

gem rdoc --all

In order to rebuild the Ruby library documentation, download the source code and run

rdoc --all --ri --op new_ri_docs

Then, replace the Ruby system ri directory, which can be found by running

ri --no-standard-docs --system --list-doc-dirs

with the new_ri_docs directory. As this release is slated to ship with Ruby 1.9.1, we would love to hear about any issues so that we can fix them quickly.
