- Update to v1.33
* Fix: running ``load.timescale(builtin=False)`` was raising an
exception ``FileNotFoundError`` if the ``finals2000A.all`` file was
not already on disk, instead of downloading the file automatically.
`#477 `_
- v1.32
* A new :func:`~skyfield.eclipselib.lunar_eclipses()` routine finds
lunar eclipses and determines their degree of totality.
`#445 `_
* The almanac module’s new :func:`~skyfield.almanac.meridian_transits()`
routine can find the moments at which a body transits the meridian and
antimeridian.
`#460 `_
* Fix: the :func:`~skyfield.searchlib.find_minima()` function was
ignoring its ``epsilon`` and ``num`` arguments and always using the
default values instead.
`#475 `_
* Fix: the ``.epoch`` attribute of Earth satellite objects that were
built using :meth:`~skyfield.sgp4lib.EarthSatellite.from_satrec()`
was, alas, a half-day off.
`#466 `_
* Fix: the :class:`~skyfield.toposlib.Topos` constructor arguments ``x``
and ``y``, which never worked properly, have been deprecated and are
now ignored.
1.31 — 2020 October 24
----------------------
* Skyfield now uses the International Earth Rotation Service (IERS) file
``finals2000A.all`` for updated ∆T and leap seconds. The USNO is no
longer updating the files ``deltat.data`` and ``deltat.preds`` that
previous versions of Skyfield used, and the ``cddis.nasa.gov`` server
from which they were fetched will discontinue anonymous FTP on 2020
October 31. See `downloading-timescale-files`.
`#452 `_
`#464 `_
* The comets dataframe built from the MPC file ``CometEls.txt`` now
includes the ``reference`` column, so users can tell which orbit is
most recent if there are several orbits for a single comet. (For
example, the file currently lists two C/2020 F3 (NEOWISE) orbits.)
The comet examples in the documentation now build a dataframe that
only includes the most recent orbit for each comet.
`#463 `_
* Two new methods :meth:`~skyfield.iokit.Loader.days_old()` and
:meth:`~skyfield.iokit.Loader.download()` make it simple to download a
fresh copy of a file if the copy on disk is older than you would like.
1.30 — 2020 October 11
----------------------
* The various ``strftime()`` Skyfield methods now support the ``%j``
day-of-year format code.
* Fix: the new Julian calendar support broke support for out-of-range
month numbers, wrapping them into the current year instead of letting
them overflow into subsequent years.
`#461 `_
* Fix: a stray debugging ``print()`` statement was stranded in ``t.dut1``.
`#455 `_
* The :class:`~skyfield.timelib.Time` object, if manually instantiated
without a Julian date fraction, now provides a fraction array with
dimensions that match the Julian date argument.
