As with any new release, it’s about new features and modernization; however, when upgrading to any new version there can be changes or deprecations that might introduce new errors into your codebase.

Unfortunately, development work on email is a bit of a chore. You have to either clog your inbox with test emails to test every little change or at best configure another awkward solution to open them in a browser.

We were doing an operation on a list of objects, the whole loop wrapped in a database transaction (more detail on defining your own transactions and using it as a context manager here), and then calling a background task for each of them. Users were reporting that the action that was supposed to be performed in the background task wasn’t happening for all of the users in the loop?—?only some of them. To make this even more fun, I was able to replicate the issue fairly consistently on production, but not at all locally. Oh, concurrency
