GLEW and openGL deprecation

I am using openGL and glew to check the extensions.

Say I wanted to check if I could use multitexture extension:

GLEW_ARB_multitexture will return true if I can use it.

BUT

arb_multitexture was deprecated in openGL 3.0.

Will it still return true?

What about in 3.1 where it was removed?

Thanks.

It'll return true if your context exports the extension, which it will if it's not "forward-compatible" or "core profile", or possibly if it supports the "GL_ARB_compatibility" extension.

The bottom line is, if GLEW_ARB_multitexture is true, you can use the functionality. Any higher-level logic (like only using shaders if they're available) is up to you.
