* Automatic closure of connections in threads is deprecated. For exampleAaron Patterson2011-11-291-1/+7
| | | | | | | | | | | | | | | | | the following code is deprecated: Thread.new { Post.find(1) }.join It should be changed to close the database connection at the end of the thread: Thread.new { Post.find(1) Post.connection.close }.join Only people who spawn threads in their application code need to worry about this change.
