I just released Authl v0.3.0; minor version bump because of a public API change, to better facilitate stateless storage.
Which is to say I converted most of the handlers to be stateless, which hopefully fixes the issues with running on Heroku.
Unfortunately Twitter couldn’t be fixed easily but I wasn’t running the Twitter handler on this site anyway. I do have some ideas but they’re fairly involved and will have to come later, and not when I’m up way past my bedtime.
Also, there still seems to be some cache-related issue that’s making it necessary to shift-reload the page after logging in or out, sometimes.
