* When you provide PyEphem with a Python ``datetime`` that has a time
zone attached, PyEphem now detects the time zone and converts the date
and time to UTC automatically.
* A new search routine had been written and tested
to power the :ref:`transit-rising-setting` methods
``previous_rising()``,
``previous_setting()``,
``next_rising()``, and
``next_setting()``.
They should no longer be susceptible to getting hung up in a loop.
You should also find them substantially faster.
* Fixed the ``constellation()`` routine so that it uses astrometric,
rather than apparent, right ascension and declination. This should
make it more accurate along the borders of each constellation.
* Fixed how the underlying “libastro” library computes whether a body’s
image is deflected by gravity when its light passes close to the Sun.
Previously, users would see coordinates jump unexpectedly as the
deflection formula turned on and off haphazardly.
* Fixed the star positions in the ``ephem.stars`` star catalog by adding
8.75 years of proper motion to each star. Previously, each 1991.25
position from the Hipparcos catalog was being incorrectly treated as a
2000.0 position.
* A new routine ``unrefract()`` lets you compute the real altitude
of a body that you observe in the sky at a given apparent altitude.
* The old ``cities.lookup()`` function is now officially deprecated.
Because of a Google API restriction, it stopped working in 2018.
* Planetary moon positions are now available through the year 2040
(previously, asking for a position past 2020 returned zeroes).
* The ``Date`` object is improved such that the return values of
