- 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.

- 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``.

- 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. (forwarded request 1060130 from bnavigator)

- 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

- Update to 1.39
  * The Angle.dstr() and Angle.hstr() methods now accept a
    format= argument that lets callers override Skyfield’s default
    angle formatting and supply their own; see Formatting angles.
    #513
  * The prototype planetary_magnitude() function now works not
    only when given a single position, but when given a vector of
    several positions.
- Release 1.38
  * Replaced the old historic ∆T table from the United States
    Naval Observatory with up-to-date splines from the 2020 release
    of the extensive research by Morrison, Stephenson, Hohenkerk,
    and Zawilski and also adjusted the slope of Skyfield’s
    near-future ∆T estimates to make the slope of ∆T much less
    abrupt over the coming century.
  * Added a full reference frame object for the TEME reference
    frame used by SGP4 Earth satellite elements.
- Release 1.37
  * Added a frame_latlon_and_rates() method that can compute the
    rates at which angles like altitude and azimuth, or right
    ascension and declination, are changing.
  * Accepted a contributor’s helpful fix for a rounding error that
    had slightly shifted a few constellation boundaries. #548
  * The Time tuple utc and method utc_strftime() are now backed by
    the same math, so they always advance to the next calendar day
    at the same moment. This makes it safe to mix values returned
    by one of them with values returned by the other. #542
  * Vector subtraction now returns the position subclass specific
    to the resulting vector’s center. #549

- Update to v1.34
  * The position classes have gained methods frame_xyz(), 
    frame_xyz_and_velocity(), frame_latlon(), and 
    from_time_and_frame_vectors() that work with a new 
    library skyfield.framelib to offer a number of familiar 
    reference frames. These replace the existing ad-hoc 
    position methods for ecliptic and galactic coordinates, 
    which are now deprecated (but will continue to be 
    supported). See Coordinates in other reference frames.
  * Added support for IERS Polar Motion 𝑥 and 𝑦.
  * Added a method lst_hours_at() that computes Local 
    Sidereal Time.
  * A new almanac routine moon_phase() returns the Moon 
    phase as an angle where 0° is New Moon, 90° is First 
    Quarter, 180° is Full, and 270° is Last Quarter. #282
  * Almanac search routines that previously returned a 
    Boolean true/false array now return an integer 0/1 
    array instead, to work around a new deprecation warning 
    in NumPy which, for example, would have outlawed using 
    the Boolean array from moon_nodes() to index into the 
    MOON_NODES list that provides a name for each node. #486
  * The undocumented columns magnitude_H and magnitude_G 
    in the Minor Planet Center comets dataframe have been 
    renamed magnitude_g and magnitude_k following further 
    research on the file format (which does not itself 
    document which magnitude model is intended). #416

- Update to version 1.29
  * Fix: the new Julian calendar feature was raising an 
    exception in the calendar methods like 
    `skyfield.timelib.Time.tt_calendar()` if the time 
    object was in fact an array of times. #450
  * Fix: trying to iterate over a time object would raise an 
    exception if the time was created through 
    `~skyfield.timelib.Timescale.ut1()`.
- Version 1.28
  * Broken URL: Because the VizieR archive apparently decided 
    to uncompress their copy of the hip_main.dat.gz Hipparcos 
    catalog file, the old URL now returns a 404 error. As an 
    emergency fix, this version of Skyfield switches to their 
    uncompressed hip_main.dat. Hopefully they don’t compress 
    it again and break the new URL! A more permanent solution 
    is discussed at: #454
  * To unblock this release, removed a few deprecated pre-1.0 
    experiments from April 2015 in skyfield.hipparcos and 
    skyfield.named_stars that broke because the Hipparcos 
    catalog is no longer compressed; hopefully no one was 
    using them.
  * In a sweeping internal change, the 
    `~skyfield.timelib.Timescale` and 
    `~skyfield.timelib.Time` objects now offer support 
    for the Julian calendar that’s used by historians for 
    dates preceding the adoption of the Gregorian calendar in 
    1582. See choice of calendars if you want to turn on 
    Julian dates in your application. #450

- Update to version 1.27
  * The printed appearance of both vectors and of vector 
    functions like Earth locations and Earth satellites 
    have been rewritten to be more informative and 
    consistent.
  * Added compute_calendar_date() which lets the caller 
    choose the Julian calendar for ancient dates instead of 
    always using the proleptic Gregorian calendar. This 
    should be particularly useful for historians.
  * Added J() that builds a time array from an array of 
    floating point years. #436
  * Added four new strftime methods for the non-UTC 
    timescales (#443). All four of them support %f for 
    microseconds, and provide a reasonable default format 
    string for callers who don’t wish to concoct their own:
      tai_strftime()
      tt_strftime()
      tdb_strftime()
      ut1_strftime() 
  * Thanks to several fixes, comets and asteroids with 
    parabolic and hyperbolic orbits should now raise fewer 
    errors.
 *  The prototype planetary_magnitude() can now return 
    magnitudes for Uranus without raising an exception. The 
    routine does not yet take into account whether the 
    observer is facing the equator or poles of Uranus, so 
    the magnitude predicted for the planet will only be 
    accurate to within about 0.1 magnitudes.

- Update to Version 1.24
  * Added methods :meth:`~skyfield.timelib.Timescale.from_datetime()`
    and :meth:`~skyfield.timelib.Timescale.from_datetimes()` to 
    the :class:`~skyfield.timelib.Timescale` class, to 
    better advertise the ability to build a Skyfield time 
    from a Python datetime — an ability that was previously 
    overloaded into the year parameter of the 
    :meth:`~skyfield.timelib.Timescale.utc()` method (where 
    it is still supported for backwards compatibility, but 
    no longer documented).
  * Fix: improved the accuracy with which velocity is 
    converted between the Earth-fixed ITRF frame that rotates 
    with the Earth and the inertial GCRS frame that does not. 
    In particular, this should make Earth satellite 
    velocities more accurate.
