- Update to 1.48 * Times now support the ``<`` operator, so Python can sort them. * For convenience, geoids like :data:`~skyfield.toposlib.wgs84` have a new attribute :data:`~skyfield.toposlib.Geoid.polar_radius`. * You can no longer subtract two positions unless they have the same ``.center``. Otherwise, a ``ValueError`` is raised. This check has always been performed when you subtract vector functions, but it was missing from the position subtraction routine. * On days that the Sun fails to rise and set in the Arctic and Antarctic, the new rising and setting routines now correctly set the value ``False`` not only for sunrise but also for sunset. - Reenable pytho312 testing with a new assay

- Update to 1.47 * Added faster and more accurate almanac routines :func:`~skyfield.almanac.find_risings()` and :func:`~skyfield.almanac.find_settings()` and :func:`~skyfield.almanac.find_transits()`. * Skyfield’s internal table for the ∆T Earth orientation parameter has been updated, so that its predictions now extend to 2025-01-18. * Constellation abbreviations are now consistent between the :func:`~skyfield.api.load_constellation_map()` table and the :func:`~skyfield.api.load_constellation_names()` list. Previously, ``CVn`` and ``TrA`` had been mis-capitalized in the list as ``Cvn`` and ``Tra``. - Skip testing python312: gh#brandon-rhodes/assay#15 still an issue

- Update to 1.46: * The :func:`~skyfield.almanac.oppositions_conjunctions()` routine now measures ecliptic longitude using the ecliptic of each specific date, rather than always using the J2000 ecliptic, which should improve its accuracy by several seconds. * Skyfield’s internal table for the ∆T Earth orientation parameter has been updated, so that its predictions now extend to 2024-04-13. * Bugfix: Skyfield was giving values several kilometers off when computing the elevation above ground level of a target that was positioned directly above the Earth’s north or south pole. * Bugfix: the function skyfield.positionlib.ICRF.is_behind_earth() method was incorrectly returning True if the Earth was on the line that joins the two satellites, but over on the far side of the other satellite where it wasn’t really in the way. * The method skyfield.positionlib.ICRF.altaz() now lives on the main position class instead of in two specific subclasses. If the user mistakenly tries to call .altaz() on an instance of the skyfield.positionlib.Astrometric position subclass - which previously lacked the method - then a friendly exception is raised explaining their error.

- Update to v1.45 * Bugfix: minor planets and comets in Skyfield 1.44 would raise an exception if asked for a position in the half of their orbit where they are inbound towards their perihelion. - Changelog v1.44 * Skyfield’s internal table for the ∆T Earth orientation parameter has been updated, so that instead of including measurements only through December 2021 it now knows Earth orientation through September 2022. * Distance and velocity objects can now be created by calling their unit names as constructors, like d = Distance.km(5.0) and v = Velocity.km_per_s(0.343). * Updated the URL from which the Hipparcos database hip_main.dat is downloaded, following a change in the domain for the University of Strasbourg from u-strasbg.fr to unistra.fr.

- Update to v1.43.1 * An attempt at overly clever scripting resulted in a Skyfield 1.43 release without a setup.py in its .tar.gz; within an hour, a Python 2.7 user had reported that Skyfield could no longer install. This release is identical to 1.43 but (hopefully) installs correctly for everyone! - Changelog v1.43 * Fixed planetary_magnitude() so it works for Saturn even when the time is an array rather than a single time; also, improved its calculation slightly with respect to Uranus. #739 * Improved load_comets_dataframe() so that parsing CometEls.txt with the most recent version of Pandas doesn’t stumble over the commas in the final field of (for example) Halley’s Comet and give the error ParserError: Error tokenizing data. C error: Expected 12 fields…saw 13. #707 - Changelog v1.42 * Added two new position methods phase_angle() and fraction_illuminated() that, given an illuminator (usually the Sun) as their argument, compute whether the observer is looking at the bright side or the dark side of the target body. They replace a pair of old functions in the almanac module. * The almanac routine moon_nodes() would sometimes skip nodes that were closer together than 14.0 days. It has been tightened down and should now detect all lunar nodes. #662 * Time objects now feature a to_astropy() method. * The position method to_skycoord() now sets the frame attribute of the sky coordinate it returns, and for now only supports barycentric and geocentric positions. #577 - Changelog v1.41 * Times now support arithmetic: you can add or subtract from a
