 * **General:**

+    Arm64 binaries for NEON, 128-bit SVE 128 and 256-bit SVE added to release

   * **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
