What versions of OpenGL are supported by GLFW?
This question likely stems from the original version of the WGL_ARB_create_context extension, which stated that the old context creation mechanism would be limited to OpenGL version 2.1. However, this is no longer the case and the extension spec has been updated accordingly. GLFW 2.6 uses only the older context creation mechanism, which may return contexts of any version, however new, provided they implement the ARB_compatibility extension. Most modern drivers do this. Explicit creation of contexts of version 3.0 and above, including profiles and flags, is supported by version 2.7, which is the current stable version. However, any version of GLFW should be able to create contexts of version 3.0 and above provided the driver supports it.
