According to the Recent Actions page, OFAC has updated Venezuela General License 5B (Authorizing Certain Transactions Related to the Petroleos de Venezuela, S.A. 2020 8.5 Percent Bond on or After April 22, 2020) and 8E (Authorizing Transactions Involving Petroleos de Venezuela, S.A. (PdVSA) Necessary for Maintenance of Operations for Certain Entities in Venezuela). At the time I first wrote this, the OFAC website was largely inoperative. It is now back up.
The change to General License 5B from 5A is that the authorized transactions, which were supposed to be as of January 22, 2020 are now as of April 22nd. Similarly, General License 8E now expires April 22nd.
