JCR is a Web application for performing and managing code reviews. Although it has some special logic for reviewing Java projects, it can be used for reviews of any type of source code. JCR manages all stages of the review process (initial project setup, individual review, joint review meeting, post-review tidy-up), but it's mainly there to show diff views of files that have changed and to allow comments to be made on any line of any file marked for review.
The failure to work with SQLAlchemy versions later than 0.4.0 was fixed. The failure to view modified files if the JCR base directory was not under the working directory was fixed. A couple of minor features were added, including templates for project notes and a working backup script for sysadmins.
