✂️ Excerpt generator
Ephemerides can be large models, from a few dozens to several hundreds of MB.
What if you only need a small time range, or only the data from the Sun?
Ephem now provides a CLI to generate an excerpt file, which leads to better performance and a smaller disk space footprint.
🧮 Support for IMCCE INPOP ephemerides
INPOP, the numerical planetary integrator from the Paris Observatory, is one of the most precise and accurate model in the world.
Ephem now supports downloading and loading INPOP models, as it already did for NASA/JPL Development Ephemeris.
A new value object has been introduced to deal with distances. It currently supports meters, kilometers and astronomical units. 📏
All distances in the library have been converted to instances of this new object.

Get moonrise and moonset times and azimuths, and the Moon upper transit time and altitude 📐
The transit is the instant when the Sun crosses the local meridian. In other terms, astronoby provides the time of the "true noon", when the Sun's is the highest in the sky, and how high it is.
Sunrise and sunset times and azimuths have been moved to a new ObservationEvents object, on which have been added the transit time and altitude. Again, first an example of how to set it up.
