   after the PEP 425 tags for each environment --
-  e.g. ``/opt/python/cp313-cp313`` contains a CPython 3.13 build, and
+  e.g. ``/opt/python/cp314-cp314`` contains a CPython 3.14 build, and
   can be used to produce wheels named like
-  ``<pkg>-<version>-cp313-cp313-<arch>.whl``.

 - Development packages for all the libraries that PEP 571/599 list. One should not assume the presence of any other development package.
