That’s great. Especially the 30$ price tag. For that amount of content I feel like people often take 100$+ - 30$ is much easier for me to spend as it’s basically a book

21.0-rc2 is out. Has been for a little while and I hadn’t noticed. Would be nice if the OTP blog would call these things out. I don’t have a good what’s new list, but it does look like the efficiency guide has been updated to remove some binary obsolete optimization quirks. Seems binary support got better.

I’m happy to see the rewritten file driver. While trying to run phoenix using a unix socket, I found sendfile was unsupported, but is now working in OTP 21.
