+NOTE: In order to not fully abandon machines affected by AMD-SB-7033 [1] that
+have not received the BIOS update, the family 19h microcode container now
+includes a second patch for these machines that brings the microcode to the
+highest possible level without the microcode signing fix. While a BIOS update
+is highly recommended to receive the latest security updates issued after the
+microcode signing vulnerability, this will allow non-updated systems to at
+least receive some microcode updates beyond the version provided by BIOS.
