What changed?
Remove search attributes keys with nil values.
Why?
Search attributes with nil values is the syntax to remove them. In practice, it just remove from the persistence map (ie., it won't store {"key": null} for example). Other than that, it was already working as expected.
How did you test it?
Launched server, ran workflow to set search attribute, and then set to nil or empty list. Checked the database to confirm the keys are not there.
Potential risks

Is hotfix candidate?
