You can check commit by commit for the newly added lints.

There's an issue with one of the new lints that requires a few ignores. See:

Not 100% sure this is equivalent? 🤔

[ritchie46]

Not exactly. Doesn't have to be an issue though. Why was it needed now?

The implementation of the serializer is now static, but borrows 'a. Which, if it compiles is fine.

[stinodego]

There's a new lint that doesn't allow eliding lifetimes if the lifetime is named elsewhere in the function definition, so Serializer has to explicitly become Serializer<'a>. Apparently the + 'a is no longer needed.
