End-Users learners cannot see tabs in Learning Catalog after 24C Update

To resolve this we had to add a privilege to our Custom Learner role (Access HCM Common Components). Can anyone provide some information as to why this change occurred between 24B and 24C? Was it in the release notes or other correspondence? Our Senior Management wanted an explanation of what occurred and how we can avoid the same scenario again as it caused major business disruption for 3 days.
