We added the following functionality to Change History settings:
Support for Cases
Change History now includes Cases (Requests, Bugs, and Risks).
See and filter events based on the Case type.
Manage Access to Project-level Change History Based on Profiles
The Change History button is accessible from Projects when enabled in System settings.
Now for even more flexibility, you can remove the button from the ribbon and contextual menus for specified Profiles. This way, you can keep the System setting enabled and hide the option for selected Profiles.
