New dataset version (tag 2022-03-31T12:00:00Z)

SARS-CoV-2 (with and without recombinants)

• Pango lineages: New lineages added up till pango-designation release v1.2.137 are now included, including among others BA.1.18-19, BA.2.4-BA.2.8 and XG-XK (in the default build, excluded from special "without recombinants" dataset).
• Dataset: The sampling of sequences has changed slightly. Previously, every Nextstrain clade got around 30 random sequences belonging to this clade causing quite a bit of movement between releases. This is no longer the case. The tree is thus slightly smaller. The change is most noticeable for small Nextstrain clades like 20F.
