The team caught some issues with templates with during our review process before merging, but then introduced new bugs with the attempted fix that weren't caught during further review. The new bug only affected instances configured for single users (not multiple users), but if a blog had any pinned posts, all blog rendering would fail and display our silly “500” error text instead of the author's writing. In other words, this wasn't an edge case, but the software catastrophically failing for a decent subset of users.
Admittedly, this is a configuration we don't currently test super-thoroughly — but nonetheless it got merged with the rest of the intended fix.
I quietly released v0.11 around 3am Japan Standard Time, and within two hours a user upgraded their instance and encountered our newly introduced bug, filing an issue for it (#207).
The bug was easily fixed when I woke up (#209), but this incident — a large release after several months, completely botched for a subset of users — made it clear we need to change how we do things in the future.
Going forward, we'll put out a Release Candidate or two before all major or minor releases. The goal will be to get more eyes on the code we're about to send out, so that we might catch silly errors like this before putting our stamp of approval on a new release.
In the meantime, skip v0.11 and enjoy WriteFreely v0.11.1! This time, you won't regret the upgrade!
