• Withdrew lineage AY.75.1 as it does not have a defining mutation in the coding region. Most sequences previously designated AY.75.1 are now designated AY.75, unless they are in lineages AY.75.2 or AY.75.3
• Added new lineage AY.75.2 with 234 new sequence designations and 46 updated from AY.75
• Added new lineage AY.75.3 with 87 new sequence designations and 300 updated from AY.75
• Merged lineage B.1.177.79 into B.1.177.60 as it does not have a defining mutation within the coding region of the genome and is a subclade within B.1.177.60. Therefore B.1.177.79 is withdrawn and the 28 sequences previously designated B.1.177.79 are now designated B.1.177.60
• Updated the designations of 864 sequences from AY.39.1 to AY.39.1.1 as they cluster within the AY.39.1.1 clade
• Updated 486 sequence designations from B.1.617.2 to AY.44 as they cluster within the AY.44 clade
• Updated 40 sequence designations from B.1.617.2 to AY.46 as they cluster within the AY.46 clade
• Removed 148 AY.43 sequence designations as they are not in the UShER tree
