Release notes

The major changes of this version:

• We have finally completed our work on accurate planet axes, including Lunar libration
• Visualisation of Earth shadow for Lunar eclipses
• Better texture for the Lunar surface
• Added the latest algorithms for planet magnitudes
• Enhanced Calendars plugin
• Replaced "arabic" by more accurate "al-Sufi" skyculture
• Planets are now scalable and Solar glare switchable for didactic applications

We have also published a scientific paper about the application of Stellarium in cultural astronomy: https://doi.org/10.1558/jsa.17822
