# Gaia Sky 3.5.0-RC6

## Features
- add eclipses by projecting the shadow umbra and penumbra from moons to planets and vice-versa. The option to outline the umbra and penumbra is given as a checkbox in the preferences. Eclipses can be deactivated, also from the preferences window, graphics tab.
- dim atmosphere w.r.t. camera, star and eclipsing body positions during eclipses.
- use coordinates provider from objects to sample periodic orbits instead of hardcoded algorithms.
- add support for VSOP2000.
- initial support for ephemeris based on Chebyshev polynomials.
- add a few showcase scripts

## Bug Fixes
- orientation locking does not work in backwards time. Fixes [#718](https://codeberg.org/gaiasky/gaiasky/issues/718).
- bump default safe mode OpenGL version to 3.3 to support instancing. GPUs from 2007 support it, so it should be safe. Also, do not attempt to compile double-precision geometry shaders in safe mode, since they are not used and may crash anyways.
- line trail mapping in non-timestamped trajectories. Fixes [#715](https://codeberg.org/gaiasky/gaiasky/issues/715).
- double-rebuilding of dataset manager on close. Also, closing the dataset manager does not persist the preferences.
- shader version for normal shader from 410 to 330 to prevent crashes in old GPUs.
