 - **[major change]** Starting with **v0.7.3**, inline print functions are disabled by default in release mode to eliminate printing costs (see the Options chapter of the docs). <br> Colored output can be disabled (see documentation).
 - **[major change]** Starting with **v0.8.3**, alternate clipspace configurations are supported. The `CGLM_FORCE_DEPTH_ZERO_TO_ONE` and `CGLM_FORCE_LEFT_HANDED` flags are provided to control clip depth and handedness. This makes it easier to incorporate cglm into projects using graphics APIs such as Vulkan or Metal. See https://cglm.readthedocs.io/en/latest/opt.html#clipspace-option-s
