It is first spotted in https://github.com/cov-lineages/pango-designation/issues/1872 S:213 is G in BA.2.75 lineages (including CH) while E in XBB lineages. Based on S:S486P, the branch gets one more XBB mutation.

Seems to me to be a really important one to watch. CH.1.1.3 with S:213E has 14 sequences as well -- so this is the second time the lineage acquired the mutation successfully.
