Deprecation warnings with Confluence client

Just started using the client (4.0.4) to access Confluence Cloud and while debugging authorization errors, I've noticed the deprecation warnings:

    < warning: 299 - "Deprecated API, will be removed on Mon, 31 Mar 2025 00:00:00 GMT"
    < deprecation: Wed, 1 Mar 2023 00:00:00 GMT

This happened with `confluence.page_exists()`

This this of concern?
