railties/CHANGELOG

 *SVN*
 
+* Added update_javascripts task which will fetch all the latest js files from your current rails install. Use after updating rails. [Tobias Luetke]
+
 * Added cleaning of RAILS_ROOT to useless elements such as '../non-dot-dot/'. Provides cleaner backtraces and error messages. [Nicholas Seckar]
 
 * Made the instantiated/transactional fixtures settings be controlled through Rails::Initializer. Transactional and non-instantiated fixtures are default from now on. [Florian Weber]
