 ### Added

+- **Added Ring Hang event**  
+Added `AMDSMI_EVT_NOTIF_RING_HANG` to the possible events in the `amdsmi_evt_notification_type_t` enum.

 - **Added process isolation and clean shader APIs and CLI commands**  
 Added APIs CLI and APIs to address LeftoverLocals security issues. Allowing clearing the sram data and setting process isolation on a per GPU basis. New APIs:
  - `amdsmi_get_gpu_process_isolation()`

 - **Fixed python interface call amdsmi_get_gpu_memory_reserved_pages & amdsmi_get_gpu_bad_page_info**  
 Previously python interface calls to populated bad pages resulted in a `ValueError: NULL pointer access`. This fixes the bad-pages subcommand CLI  subcommand as well.
