Maintenance status

Hi there, I was wondering about the maintenance status of this crate? There seems to be little activity. As a rustls maintainer, I noticed this is one of the most popular rustls dependents that's still on a pretty old version, which seems tricky for a security-sensitive crate.

The issue names no file, test, or concrete change. Start by reviewing the crate's current dependency metadata and maintenance history, then clarify whether the expected outcome is a dependency update or a documented maintenance decision; completion cannot be defined until that scope is agreed.
