Release Notes

Bug Fixes

• stuttering updating counts top-down in large octrees, now the counts are updated locally, bottom-up, when octants are loaded/unloaded
• RAM units in crash report, add indentation
• default proper motion factor and length values
• ‘App not responding’ message on win10 - fix by upgrading to gdx-controllers:2.0.0, plus some other goodies
• remove useless network checker thread, fix thumbnail URL crash on Win10
• minimizing screen crashes Gaia Sky on Win10. Fixes #333, #345 #333
• VR init failure actually prompts right error message
• properties files’ encodings set to UTF-8. Fixes #344 #344
• VR mode now accepts any window resize, backbuffer size used for everything internally
• BREAKING CHANGE API landOnObjectLocation() -> landAtObjectLocation()
• octreegen additional split accepts now coma and spaces
• use different sprite batch for VR UI with backbuffer size
• pan scaled with FOV factor
• red-night theme disabled styles
• proper ‘disabled’ textures for buttons
• labels occlude objects behind, buffer writes disabled.
• download speed moving cancel button in dataset manager
• safemode flag used correctly, fix raymarching not being setup in safe mode

Build System

• auto-update offered through install4j, backup solution in-app still available when not launched using install4j
• remove sdl2gdx in favor of gdx-controllers:2.0.0
• exclude old gdx-controllers library
• add –parallelism parameter to
• fix script so that geo-distances file is additional data instead of special argument
• fix helper script arguments
• update release instructions with Flatpak, fix build script

Code Refactoring

• interface particle record to allow for multiple implementations
• binary providers are versioned, fix binary version 0/1 loading
• increase number of maps for octree gen
• modify default bloom settings (default intensity, passes, amount)

Documentation

• fix javadocs for binary format

Features

• add warning when selecting more than one star catalog
• add white core to star shaders
• add T_eff to STIL-loaded catalogs
• add color conversion by Harre and Heller
• add output format version argument to octree generator
• support for in catalog selector
• add versioning to binary catalog format. Create new, more compact version
• improve information of version line in welcome and loading screens
• add GL info to welcome screen
• new connection to wikipedia REST API to show content in a window
• add unsharp mask post-processing filter
• new checkbox textures, adjust window visuals
• dataset selection dialog uses same structure as dataset manager
• time warp slider instead of buttons
• new fractional UI scaling
• add regexp to some column names for STIL loader, add invalid names array
• case-insensitive columns in STIL loader, enable FITS loading

Performance Improvements

• arrays of size not dependent on maxPart for octreegen
• remove boundingBox from octant, reduce memory token duplication
• replace extra attributes hashmap with objectdoublemap for RAM compactness
• do not write star name strings if they are the same as ID, velocity vectors represented with single-precision floats
• reduce main memory usage of stars by adjusting data types
• switch to unordered gdx Arrays when possible to minimize copy operations
• replace java.util.ArrayLists with Libgdx’s Arrays to minimize allocations
• index lists are of base types, use dst2 for distance sorting
• improve memory usage of extra star attributes and fix render system unnecessary setUniform calls
• reduce memory usage in particle groups -> no metadata array

Style

• fix missing coma in night-red theme JSON file
• update thread names, fix monitor objects, increase scene graph update time interval
