+- [Performance] Update to latest Zopfli with greatly improved performance.
+- [Improvement] Reduce memory usage.
+- [Bugfix] Correct handling of grayscale conversion when ICC profile is present.
+
 ## Version 9.1.4
 
 - [Improvement] Improve optimization of APNG files (reductions still not supported yet).

+          Set the maximum number of threads to use. Oxipng uses multithreading to evaluate multiple
+          optimizations on the same file in parallel as well as process multiple files in parallel.
