Added tmp/sessions, tmp/cache, and tmp/sockets as default directories in the Rails skeleton [DHH] Changed the default session configuration to place sessions in tmp/sessions, if that directory is available, instead of /tmp (this essentially means a goodbye to 9/10 White Screen of Death errors and should have web hosting firms around the world cheering) [DHH] Added a default configuration of the FileStore for fragment caching if tmp/cache is available, which makes action/fragment caching ready to use out of the box with no additional configuration [DHH] Changed the default configuration for lighttpd to use tmp/sockets instead of log/ for the FastCGI sockets [DHH]

railties/CHANGELOG

 *SVN*
 
+* Changed the default configuration for lighttpd to use tmp/sockets instead of log/ for the FastCGI sockets [DHH]
+
+* Added a default configuration of the FileStore for fragment caching if tmp/cache is available, which makes action/fragment caching ready to use out of the box with no additional configuration [DHH]
+
+* Changed the default session configuration to place sessions in tmp/sessions, if that directory is available, instead of /tmp (this essentially means a goodbye to 9/10 White Screen of Death errors and should have web hosting firms around the world cheering) [DHH]
+
+* Added tmp/sessions, tmp/cache, and tmp/sockets as default directories in the Rails skeleton [DHH] 
+
 * Added that script/generate model will now automatically create a migration file for the model created. This can be turned off by calling the generator with --skip-migration [DHH]
 
 * Added -d/--database option to the rails command, so you can do "rails --database=sqlite2 myapp" to start a new application preconfigured to use SQLite2 as the database. Removed the configuration examples from SQLite and PostgreSQL from the default MySQL configuration [DHH]
