hi.i just notice that:

GL 3.3 Core spec Chapter E.2.2  Removed Features (title)  page 345  says

"""
• Legacy pixel formats - all ALPHA, LUMINANCE, LUMINANCE_ALPHA, and
INTENSITY external and internal formats, including compressed, floating-
point, and integer variants; all references to luminance and intensity formats
elsewhere in the specification, including conversion to and from those for-
mats; and all associated state. including state describing the allocation or
format of luminance and intensity texture or framebuffer components.
