 - **[major change]** by starting v0.7.3, inline print functions are disabled in release/production mode to eliminate print costs (see options in documentation). Print output also improved. You can disable colors if you need  (see documentation)
+- **[major change]** by starting v0.8.3, **cglm** supports alternative clipspace configuations e.g. Left Handed, Zero-to-One (_zo)... `CGLM_FORCE_DEPTH_ZERO_TO_ONE` and `CGLM_FORCE_LEFT_HANDED` is provided to control clipspace. You should be able to use **cglm** with Vulkan, DirectX and Metal now... see https://cglm.readthedocs.io/en/latest/opt.html#clipspace-option-s
