Status: February 2025

The 5.2.0 release is a minor maintenance release.

  • General:
    • Change: Changed sRGB alpha channel endpoint expansion to match the revised Khronos Data Format Specification (v1.4.0), which reverts an unintended specification change. Compared to previous releases, this change can cause LSB bit differences in the alpha channel of compressed sRGB images.
    • Feature: Arm64 builds for Linux added to the GitHub Actions builds, and Arm64 binaries for NEON, 128-bit SVE, and 256-bit SVE added to release builds.
    • Feature: Added a new codec API, astcenc_compress_cancel(), which can be used to cancel an in-flight compression. This is designed to help make it easier to integrate the codec into an interactive user interface that can respond to user events with low latency.
    • Bug fix: Removed incorrect static variable qualifier, which could result in an incorrect tune_mse_overshoot heuristic threshold being used if a user ran multiple concurrent compressions with different settings.
