2025-12-16--20-07-31Z

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.

2025-12-12--16-44-41Z

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).

2025-12-10--14-52-38Z

This release contains changes for datasets:

• Mpox virus (All clades) (nextstrain/mpox/all-clades)
• Mpox virus (Clade I) (nextstrain/mpox/clade-i)
• Mpox virus (Clade IIb) (nextstrain/mpox/clade-iib)
• Mpox virus (Lineage B.1) (nextstrain/mpox/lineage-b.1)

Mpox virus (All clades) (nextstrain/mpox/all-clades)

• Breaking change: outbreak nomenclature now follows the system described in Ruis et al. (2025). As a result, outbreak hMPXV-1 is now called sh2017. In addition, the clade Ib outbreak is labeled as outbreak sh2023, and the clade Ia outbreak described in Wawina-Bokalanga et al. (2025) is labeled as outbreak sh2024.
• The clade Ib/IIb recombinant described in Pullan et al. (2025) is included in the reference tree with the ad-hoc clade and outbreak labels Ib/IIb and rec2025, respectively.

Mpox virus (Clade I) (nextstrain/mpox/clade-i)

• Breaking change: outbreak nomenclature now follows the system described in Ruis et al. (2025). As a result, outbreak hMPXV-1 is now called sh2017. In addition, the clade Ib outbreak is labeled as outbreak sh2023, and the clade Ia outbreak described in Wawina-Bokalanga et al. (2025) is labeled as outbreak sh2024.

Mpox virus (Clade IIb) (nextstrain/mpox/clade-iib)

• Breaking change: outbreak nomenclature now follows the system described in Ruis et al. (2025). As a result, outbreak hMPXV-1 is now called sh2017.

Mpox virus (Lineage B.1) (nextstrain/mpox/lineage-b.1)

• Breaking change: outbreak nomenclature now follows the system described in Ruis et al. (2025). As a result, outbreak hMPXV-1 is now called sh2017.
