* 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 1.25
* Added skyfield.data.stellarium.parse_constellations()
and skyfield.data.stellarium.parse_star_names()
to load Stellarium star names and constellation lines.
Constellation lines are featured in a new example script
neowise-chart that produces a finder chart for
comet C/2020 F3 NEOWISE.
* The Hipparcos star catalog should now load faster, having
switched behind the scenes to a higher performance Pandas
import routine.
* Fixed the ability of skyfield.timelib.Timescale.utc()
to accept a Python datetime.date object as its argument.
#409
* Slightly lowered the precision of two tests when they
detect that Python is compiled for a 32-bit processor, so
the test suite can succeed when contributors package
Skyfield for 32-bit Linux. #411
- use upstreams custom test runner 'assay'
* The runner does not have any releases yet. No package
available, so use assay-master-252.79f5d78.tar.gz directly
* drop skyfield-pr405-replace-assay-by-pytest.patch
* gh#brandon-rhodes/assay#6, gh#skyfielders/python-skyfield#405
- the unit test expect a truncated hipparcos catalog
* generate-hipparcos.sh
* hip_main.dat.gz
- drop skyfield-pr404-comparefloat.patch addressed upstream
gh#skyfielders/python-skyfield#404

* 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.
- rebase patches skyfield-pr404-comparefloat.patch
and skyfield-pr405-replace-assay-by-pytest.patch
