I'm not rushing to update to this version. First, I want to understand the changes they made to combat spam in the blocks. They look suspicious to me.

https://github.com/bitcoin/bitcoin/pull/29412 p2p: Don't process mutated blocks

https://github.com/bitcoin/bitcoin/pull/29524 p2p: Don't consider blocks mutated if they don't connect to known prev block
