Today, Monday, DreamHost will begin to roll out version 1.2.1 of Rails.
The main features of the new Rails 1.2 is the REST (and general HTTP appreciation) support (e.g. mime types, HTTP status codes, etc.) and multibyte-safe UTF-8 support.
If you’re running the popular Rails blogging engine Typo, you’re encouraged to freeze Rails immediately. If you’re running other critical applications you might want to freeze your Rails as well to avoid any complications until you’ve tested the new version.
A number of new gems are also currently being rolled out: ajax_scaffold_generator (generator for ajaxified scaffolds), camping (miniature rails), gruff (beautiful graphs for one or multiple datasets), hoe (write Rakefiles easier and cleaner) and unicode (unicode normalization library).
Finally a number of gems have been upgraded: actionmailer (1.2.5), actionpack (1.12.5), actionwebservice (1.1.6), activerecord (1.14.4), acts_as_taggable (2.0.2), capistrano (1.3.1), daemons (1.0.3), ferret (0.10.13), gen (0.41.0), geoip (0.3.0), glue (0.41.0), nitro (0.41.0), og (0.41.0), ParseTree (1.6.3), rubyforge (0.4.0) and RubyInline (3.6.2).
