Hot on the heels of this, I've released SimpleWebAuthn v13.2.1 with a fix for extremely long user IDs in registration options when using Node Buffers. It turns out Buffers pre-allocate 8192 bytes and all of them were getting encoded to Base64URL even though they were empty 😱

Oh cool, SimpleWebAuthn got a shout-out in one of Cursor's videos 🎉

...I only spotted a few issues with the PR 👀

I finished my first No Man's Sky expedition, Expedition 19. The cosmetics and companion I unlocked along the way are okay. But what I appreciate the most is how much more knowledgeable I am now about corvettes and what you can do with them. I'm feeling the game sucking me back in 😂

Family Lending of Virtual Game Cards on Switch sounds great, but it's unclear if physical proximity is a hard requirement when lending to a member of the Family 🤔

The Direct said the consoles have to be proximate, but later some fine print says it's possible to connect online to start a lent game?
