Update available - how to be notified ?

Hey!

I haven't take time to come on the website since a long time...
There's an alpine 3.6 on a Raspberry Pi v1, and I saw 3.7.0 is available.

On the docs, I read we need to edit /etc/apk/repositories, then replace in my case 3.6 to 3.7 in the text lines.
Then apk update, apk upgrade, lbu commit, reboot (I'm not wrong ??)

But is there a way to be notified about a new release like this 3.7 ?
I don't see any RSS on the website... No newsletter...

Do have I missed something ?

Many thx for your work, and your answer :)
Happy new year!
