Our Commentary ​

It's always good practice to test against release candidates, and Simon's anecdote about finding a bug in Python 3.10 after it shipped is a stark reminder of why. While Python isn't strictly 'web dev,' it underpins so much of our tooling and backend infrastructure that keeping an eye on these releases is just smart. We'll be updating our CI to include this RC soon.
