- Update to 1.35
* Deprecated the old Topos class, which not only featured
a clunky interface but hid from users the fact that
Skyfield was generating IERS2010 positions from latitude
and longitude when in fact nearly all users want WGS84
positions. Users are now encouraged to supply latitude
and longitude to the
:meth:`~skyfield.toposlib.Geoid.latlon()` method of
either the :data:`~skyfield.toposlib.wgs84` object or the
:data:`~skyfield.toposlib.iers2010` object. Related
discussion: #372
* The two new geoid objects
:data:`~skyfield.toposlib.wgs84` and
:data:`~skyfield.toposlib.iers2010` have also provided a
happy new home for the
:meth:`~skyfield.toposlib.Geoid.subpoint()` method —
which was previously stranded over on the
:class:`~skyfield.positionlib.Geocentric` class, where it
couldn’t be used with positions of other classes that
might be centered at the geocenter. (The old method will
remain in place to support legacy code, but is
discouraged in new applications.)
* The effects of :ref:`Polar motion` — if configured —
are now included both when computing the position in
space of an Earth latitude and longitude, and when
determining the latitude and longitude beneath a
celestial position.
* Added :func:`~skyfield.api.load_constellation_names()`.
* The :meth:`~skyfield.timelib.Time.utc_jpl()` method now
correctly designates its return value as UTC instead of
