Redirection is now being developed on Github. I’ve been running it there for a few months now and have already received several pull requests and fixes. It’s a good place for other people to contribute.
It’s also the best place to report any bugs or feature suggestions (anything sent to me by email tends to disappear into a black hole, and patrolling the WordPress.org forums is very time-consuming).
If you’d like to run with the latest version of the plugin then please do use the Github repo as the canonical ‘trunk’ version. The more people that do this, the less likely I am to release something that breaks sites.
I’ve yet to put a working git-to-SVN system together so I’ll manually sync things over to the WordPress.org SVN repository when ready for release.
That all-important link:
I look forward to seeing how it develops!
