I updated to the Trunk version of GLFW and I’m finding that glfwSleep isn’t really working (seems like its skipping it), is it part of the threading system that has been deprecated? Thanks. ---

Also, it only suspends the calling thread, which requires threading API specific code on some platforms. ---
