 ### Add status_reason Column
 
 A new column `status_reason` has been added to the `pa_operation` table.

+### MSSQL Server Snapshot Isolation
+
+In case you use PowerAuth server with Microsoft SQL server, enable the SNAPSHOT isolation to avoid deadlocks.
+
+You can enable the SNAPSHOT isolation mode using following query:
+
+```sql
+ALTER DATABASE [powerauth_database] SET ALLOW_SNAPSHOT_ISOLATION ON;
+ALTER DATABASE [powerauth_database] SET READ_COMMITTED_SNAPSHOT ON;
+```
+
+The SNAPSHOT transaction isolation level is enforced automatically by PowerAuth server when database sessions are started using following query:
+
+```sql
+SET TRANSACTION ISOLATION LEVEL SNAPSHOT;
+```
