+- 29 April 2022: Update default mask parameters to mask 200 bases from the end of the genome rather than the existing 50. This was necessary because there is a large deletion in this region in circulating 21L viruses. This deletion is causing problems with alignment and the resulting mis-alignment appears as excess mutations in the tree. [PR 939](https://github.com/nextstrain/ncov/pull/939).
 
 - 27 April 2022: Include new clades 22A, 22B and 22C, where 22A corresponds to Pango lineage BA.4, 22B corresponds to Pango lineage BA.5 and 22C corresponds to Pango lineage BA.2.12.1. Please see [PR 933](https://github.com/nextstrain/ncov/pull/933) for rationale behind these clade updates.
