4.6.0

Status: November 2023

The 4.6.0 release is a minor release with a few code quality improvements, and a small performance boost.

Reminder - the codec library API is not designed to be binary compatible across versions. We always recommend rebuilding your client-side code using the updated astcenc.h header.

  • General:
    • Bug-fix: Fixed context allocation for contexts allocated with the ASTCENC_FLG_DECOMPRESS_ONLY flag.
    • Bug-fix: Reduced use of reinterpret_cast in the core codec to avoid strict aliasing violations.
    • Optimization: -medium search quality no longer tests 4 partition encodings for block sizes between 25 and 83 texels (inclusive). This improves performance for a tiny drop in image quality.
    • Optimization: -thorough and higher search qualities no longer test the mode0 first search for block sizes between 25 and 83 texels (inclusive). This improves performance for a tiny drop in image quality.
    • Optimization: TUNE_MAX_PARTITIONING_CANDIDATES reduced from 32 to 8 to reduce the size of stack allocated data structures. This causes a tiny drop in image quality for the -verythorough and -exhaustive presets.
