Reporting bugs

We use GitHub issues to track bugs. Issues are logged on individual project repositories, but you can view all issues collected together here.

If you'd like to report a new bug, first check that the issue hasn't already been filed by searching through the board above. If this is a new bug, you can report it by opening a new issue on the appropriate repository. If you're not sure which repository is most appropriate for the issue, you can email us instead at

Write detailed bug reports

Ensure that your report clearly indicates both the behaviour that you expect to see, and the behaviour that you are actually seeing. Ideally, please also include a list of steps to reproduce the error you are seeing. The project repository should be pre-configured with appropriate issue templates, so please try to follow those directions!
