- default distance of “observer” to the parent
- handling of lighting factor when rendering lunar eclipse
- AstroCalc/RTS tool
- another missing timezone
- location changes via Search panel and “Goto” Action
- return to default location (with default landscape)
- other place where location name is printed in bottom bar
- pixelized panel icons in screenshots
- a possible security issue
- DSO filters
- screenshot size
- a potential security issue when storing screenshots
- scaling of screen geometry when setting window position
- limits for altitudes in Satellites plugin
- working the filter in shortcut dialog for Qt5-based builds
- storing DSO with designations in Observing lists
- the type/objtype bug in Observing lists
- creation of default empty list at start in Observing lists
- behaviour for ‘Reload the sky culture’ feature
- a crash when observer is on the spaceship

Changed:
