[Question] Changelog for unbundled models

[ishaan-sfx]

I'm currently using the following dependency in my Android project:

com.google.android.gms:play-services-mlkit-face-detection:17.1.0

The last SDK update for this version was in 2022, as documented here: https://developers.google.com/ml-kit/release-notes
However, since the face detection unbundled model is delivered via Play Services, I want to clarify the following:

1. Are there any recent updates to the underlying face detection model delivered through Play Services since 2022?
2. If so, where can I find the release notes or changelog for such updates?

The lack of documentation for unbundled model updates makes it challenging to verify regressions.
