New sanctions against Russia have all been incorporated into HM Treasury’s list of sanctioned entities, which can be found at the link below.
Also on this page are details of the format changes on the sanctions list. If you are importing data from the list, a format change will probably require some work on your import. The old format is longer updated since the end of February 2022.
If you are using a third party engine to drive sanctions checking, then you should confirm with them directly that they have updated.
