We are glad to present our new development site, http://code.opencv.org. From now on, the site will be the place to get cutting-edge OpenCV snapshots, access our repository and to report bugs/post requests.

https://code.ros.org/svn/opencv/ will be available in read-only mode for a short period of time before it's completely removed.
https://code.ros.org/trac/opencv/ - all the open tickets have been migrated to Redmine at code.opencv.org.

Happy OpenCV'ing!
