Keyframes and camera path file saving no longer overwrites existing files. Instead, it generates a new unique file name based on the given one.
Support comma- as well as whitespace-separated values for camera and keyframes files. Default to comma-separated values for writing.
Add support for OptFlowCam (Piotrowski 2024) method to convert keyframes into camera path files. Gaia Sky calls the local python3 interpreter to process the keyframe files, so a local python3 installation (with numpy) needs to be in place for it to work.

3.5.920 Feb 2024 03:15
minor feature:
Full changelog
:

Concurrency error in procedural generation progress bar update actions.
Present filter results in dataset manager in expanded panes.
Prevent the creation of multiple dataset preferences window for the same dataset.

Separate filters from dataset preferences into their own button/window in datasets pane.
Add affine transformations to all datasets (particle group, star group, variable star group, billboard group, orbit elements group). These transformations are applied in the shaders so that they can be updated on the fly. The billboard group object has been moved inside the generic catalog archetype; the Milky Way appears as a dataset now.

Dataset detection to use dataset key by default instead of name.
Graphics quality update is now a 'needs restart' operation, otherwise the system crashes trying to load in new parameters, textures and so on. This is part of.
Increase constellation and boundaries line width to prevent rastering artifacts. This is part of.
Add orientation to shape dialog (camera, equatorial, ecliptic, galactic).
Tooltips in number validators using the `MAX_VALUE` or `MIN_VALUE` should use infinity instead. Part of.
Remove all shapes around object actually removes all shapes and not only the first in the list. This is part of.
Default to scientific notation only when abs(num) 9999.
Possible null pointer exceptions in OpenXR driver.
Star flickering due to quad sizes mended by setting a minimum quad solid angle roughly equal to the pixel size of the back-buffer.

3.5.7-329 Dec 2023 14:53
minor feature:
### Bug Fixes
- columns corresponding to the same UCD maintain the order of appearance in the source table when used.
- use concurrent hash set in 'selecting' list in the OpenXR input listener to prevent concurrent modification errors.
- resizing log window does not resize contents. Fixes #749 (https://codeberg.org/gaiasky/gaiasky/issues/749).
- prevent getting name from second closest if it is invalid. Fixes #750 (https://codeberg.org/gaiasky/gaiasky/issues/750).
- use logical keys instead of key codes by converting GDX's codes to GLFW, which uses the logical keyboard layout. Fixes #748 (https://codeberg.org/gaiasky/gaiasky/issues/748).
- rename makefile, update build script to detect `/opt/gaiasky` installation.
- use default mappings file if the configured one does not exist.

Add tooltips to keyframe playback buttons.
Move `onlyBody` trajectory attribute to `bodyRepresentation`, which is an enum that enables the representation of only body, only orbit or both. The `onlyBody` attribute is still kept as a proxy. Rename `pointColor` to `bodyColor` in trajectories. `pointColor` is kept as an alias.
Skip back/fwd, step back/fwd, play/pause and timeline slider all work. Move keyframes logic and model to keyframe manager.
Add direct playback capability to keyframes. Still WIP.
Keyframe system to use new camera path object in export operation.
Move from buffered file-backed recording and playback to model-backed solutions for the camrecorder. This means that, during recording, the data is captured and stored in memory and persisted to disk when the recording finishes. During playback, the data is loaded to memory at once at the b

Full changelog
Features:
Add control for maximum number of velocity vectors per star set in preferences dialog, performance section.
Add CLI flag to force HiDPI mode either to 'Logical' or 'Pixels'.

Add `trailMinOpacity` to trajectories. This raises the opacity of a trail to the given minimum value.
Speeding up and slowing down time can be done by pressing and holding '.' and ',' respectively. No more frantically clicking a key. Also, the time warp change is smooth now.
Add camera position/orientation named bookmarks, additionally to the already existing object bookmarks. Add bookmarks for many eclipses in the default bookmarks.txt.
Use coordinates provider from objects to sample periodic orbits instead of hardcoded algorithms.
Dim atmosphere w.r.t. camera, star and eclipsing body positions during eclipses.
Initial support for ephemeris based on Chebyshev polynomials.
Add support for VSOP2000.

Scripts showing an object on a horseshoe orbit around Jupiter.
Update wording on point and line styles in preferences dialog to make it more concise and clear.

Use a geometry shader to generate the triangles in the polyline quadstrip renderer instead of the CPU. Performance is much improved.
Add geometry shader stage (optional) to shader program provider and to extended shader pr
