Dynamics 365 Auditset Table

Hi,

I've just been trying to run a report on last login for users on Dynamics 365.

Does anyone know why the AuditSet table is available over the older Odata connector (https://<instancename>.api.crm4.dynamics.com/XRMServices/2011/Organization.svc) but it isn't visible in the slightly faster API connector: https://<instancename>.api.crm4.dynamics.com/api/data/v8.2?

It may not make much difference and we should really be on the Data Export solution anyway.  Are there any ways of getting the audit data downloaded/grouped over the faster connector?  There's not point in doing an export to Excel or SRSS and bringing that into PBI as we might miss people who are logging in after the export is generated.

Many thanks
