Here are the release notes and a few highlights that jumped out at me:
From Bitcoin Core 22.0 onwards, macOS versions earlier than 10.14 are no longer supported.
Bitcoin Core 23.0 will be an excellent excuse to upgrade to Catalina.
Added support for running Bitcoin Core as an I2P (Invisible Internet Project) service
Glad to learn something new.
Release binaries are now produced using the new guix-based build system.
We now support up to 20 keys in
It was 16 multisig, buit it was supposed to be 20, and now it is. Great for when you have four more friends.
External signers such as hardware wallets can now be used.
Easing the use of hardware wallets with Bitcoin Core nodes is the best scenario for using Bitcoin. It combines the best of the best (node and hardware wallet) in an easy-to-use package. It is inspiring to see.
