This release contains changes for datasets: - Mpox virus (All clades) (nextstrain/mpox/all-clades) ## Mpox virus (All clades) (nextstrain/mpox/all-clades) - Fix clade labeling of some clade Ia sequences wrongly reported as `unassigned` instead of `Ia`. - Add some newly released sequences.

This release contains changes for datasets: - Mpox virus (All clades) (nextstrain/mpox/all-clades) ## Mpox virus (All clades) (nextstrain/mpox/all-clades) - Add placement priors to discourage attachment at the recombinant clade Ib/IIb. Previously, short sequences would be called recombinant even if they could just as well be clade Ib (which they more likely are).
