 --------------------------
 Changes in 1.9 (not yet released)
 
+- CImageWriterPNG now also supports the writeImageToFile param to allow setting compressing level. 0 stays default, 1-10 for range increasing compression level.
 - Add io::IUserData which can be set in SMaterial to make it easer passing additional material values to shaders
 - Add lens shift support for the camera and the perspective projection functions
 - TGA loader no longer reduces 24&32 bit TGA's with palettes to 16 bit. Thanks @erlehmann for report: https://irrlicht.sourceforge.io/forum/viewtopic.php?t=52925
