Yii upgrade path

Today I upgraded an application from Yii 1.0.9 to 1.0.10, which went fine.

But there’s one thing I don’t like about the upgrade process. We use subversion for our projects, and when I dropped in the new version of the framework codebase, every single file got marked as changed, because of this line:

 * @version $Id: CCacheHttpSession.php 1136 2009-06-17 13:16:14Z qiang.xue $

Every single file in the framework will register as "changed" because of this one line, making it impossible for me to review the actual changes, unless I were to go diff file-by-file through every single file.

Is there a way to tell SVN to ignore those lines?

You could use SVN external dependency feature and point to the corresponding yii svn path.
