Sun Aug 2 11:51:04 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.26
|
||
* The official ∆T files on NASA’s FTP server have stopped receiving
|
||
updates — they have no new data beyond February, the start of the
|
||
global pandemic. Unless they are updated by next February, older
|
||
versions of Skyfield will unfortunately download the files all over
|
||
again every time `skyfield.iokit.Loader.timescale()` is called
|
||
(unless the ``builtin=True`` parameter is provided). To make Skyfield
|
||
less fragile going forward:
|
||
1. The loader’s `skyfield.iokit.Loader.timescale()` method now
|
||
defaults to ``builtin=True``, telling it to use the ∆T and leap
|
||
second files that ship with Skyfield internally. To download new
|
||
∆T files from NASA and the leap second file from the International
|
||
Earth Rotation Service, specify ``builtin=False``.
|
||
2. The concept of an “expired” file has been removed from ``load()``.
|
||
Skyfield is now much simpler: if a file with the correct name
|
||
exists, Skyfield uses it. See `downloading-timescale-files`
|
||
if you still want your application to check the age of your
|
||
timescale files and automatically download new ones.
|
||
* The `ICRF.separation_from()` method now officially supports the
|
||
combination of an array of positions with a single reference position!
|
||
Its previous support for that combination was, alas, accidental, and
|
||
was broken with the 1.23 release.
|
||
`#414 <https://github.com/skyfielders/python-skyfield/issues/414>`
|
||
`#424 <https://github.com/skyfielders/python-skyfield/issues/424>`
|
||
* A prototype `skyfield.magnitudelib.planetary_magnitude()`
|
||
routine has been added with support for several planets.
|
||
`#210 <https://github.com/skyfielders/python-skyfield/issues/210>`
|
||
* The ``utc`` timezone that Skyfield returns in Python datetimes is now
|
||
either the Python Standard Library’s own UTC object, if it supplies
|
||
one, or else is defined by Skyfield itself. Skyfield no longer
|
||
silently tries importing the whole ``pytz`` package merely to use its
|
||
UTC object — which also means that the timezone returned by Skyfield
|
||
longer offers the non-standard ``localize()`` method.

Sat Jul 25 11:43:28 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- 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

Wed Jul 22 14:42:06 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||

-------------------------------------------------------------------
|
||
Wed Jul 22 14:13:46 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- 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.
|
||
- rebase patches skyfield-pr404-comparefloat.patch
|
||
and skyfield-pr405-replace-assay-by-pytest.patch

|
||
|
||
- mention python-skyfield-rpmlintrc to specfile: don't warn about

||
matplotlib and html5lib in Requires

-------------------------------------------------------------------
|
||
Fri Jul 10 14:51:52 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to Version 1.23
|
||
* Added `kepler-orbits` support for generating the positions of comets and
|
||
asteroids from Minor Planet Center data files.
|
||
* Added `skyfield.positionlib.ICRF.is_behind_earth()` to determine whether a
|
||
celestial object is blocked from an Earth satellite’s view by the Earth
|
||
itself.
|
||
* Replaced the awkward and hard-to-explain rough_period search parameter with
|
||
the conceptually simpler step_days parameter, and updated the instructions
|
||
in `searches` to match.
|
||
* Made the `skyfield.iokit.Loader.load.tle_file()` import method less strict
|
||
about Earth satellite names: any text on the line before two lines of TLE
|
||
data is now saved as the satellite name. A parameter skip_names=True turns
|
||
this off if, for particular TLE files, this leads to unwanted text being
|
||
saved
|
||
- directly copy downloaded testfiles as sources
|
||
- move skyfield-openSUSE-comparefloat.patch to skyfield-PR404-comparefloat.patch
|
||
and submit upstream: gh#skyfielders/python-skyfield#404
|
||
- move skyfield-openSUSE-replace-testrunner.patch to
|
||
skyfield-PR405-replace-assay-by-pytest.patch and submit upstream:
|
||
gh#skyfielders/python-skyfield#405
|
||
- disable python2 package
