You can read the full list of Release Notes for 7.2 SP2 here.
Some of the new features that were included in this Service Pack:
Entra:
Added support for the fw Server app's "Allow Mail" to send Emails via the Microsoft Graph API.
Requests:
Fixed an issue where Request re-submission emails were sent to each Approver individually, rather than one email to all.
When global request status is changed requestors will now only receive one email that includes the approver who triggered the status change.
Reports:
Fixed a bug causing the Report Setting "Compute Rates (Slower)" to wrongly revert to default "No" preventing the correct rate information to get displayed.
Various improvements on the Shift Schedule Report
