Add stack usage reduction to ChangeLog
@@ -16,6 +16,10 @@ The 3.4 release introduces another round of optimizations, removing a number
of power-user configuration options to simplify the core compressor data path.
* **General:**
+ * **Feature:** Many memory allocations have been moved off the stack into
+ dynamically allocated working memory. This significantly reduces the peak
+ stack usage, allowing the compressor to run in systems with 128KB stack
+ limits.
* **Feature:** Builds now support `-DBLOCK_MAX_TEXELS=<count>` to allow a
compressor to support a subset of block sizes. This can reduce binary size
and runtime memory footprint, and improve performance.
