I believe the SARS-CoV-2 variant BA.5.12 has been missed within the last few updates. It looks like every single known variant since the latest version was designated; except for BA.5.12
Additional context
BA.5.12 was designated 2023-02-23 10:47:30+0000
Omicron Phylogenetic Tree with NextClade Variant Availability indicators
- Red is unavailable
- Black is available
It makes sense that XBB.2.9 is not available via NextClade as it was designated on the same day as the latest dataset version, but BA.5.12's unavailability seems like a bug.
Note: If BA.5.12 is available via NextClade (and there is a bug in my code), please share with me how I can identify the correct lineages. I use the latest dataset version's tree.json file
