New dataset version (tag 2022-04-08T12:00:00Z)

SARS-CoV-2 (with and without recombinants)

• Pango lineages: New lineages added up till pango-designation release v1.4 are now included, including among others BA.4-5, BA.2.9-BA.2.13 and XM-XS (in the default build, excluded from special "without recombinants" dataset). For now, BA.4-5 are included in Nextstrain clade 21L, together with BA.2 which is the most similar Omicron.
• Reference tree: The first 100 and last 200 sites (with respect to Wuhan reference) are now masked in the reference tree to reduce noise due to sites like 21 that were artifactually polymorphic.
