- Removed 95 sequence names from the designations that are potentially associated with multiple samples
- Merged AY.9.1 into AY.9.2 as they likely form a single clade. AY.9.1 is therefore withdrawn
- Updated 1156 sequence designations from B.1.1 to B.1.1.307 as they cluster within the B.1.1.307 clade in the UShER tree and have the defining mutation
- Updated 1060 sequence designations from B.1.596 to B.1.2 as they cluster within the B.1.2 clade in the UShER tree and have the defining mutation
