Changes to the Imaging Subset
The subset of blending features described by BlendEquation, BlendColor,
and the BlendFunc modes CONSTANT COLOR, ONE MINUS CONSTANT COLOR,
CONSTANT ALPHA, and ONE MINUS CONSTANT ALPHA are now supported. These
feature were available only in the optional imaging subset in versions
1.2 and 1.3 of the GL.

If I interpret this correctly, it means glBlendEquation was optional
before 1.4 and thus could not be called directly.

Just below that paragraph :
"Blend squaring was promoted from the GL NV blend square extension."

So if we have 1.4, we have NV_blend_square too.

And finally D.9.6 p263 seems to indicate that EXT_blend_minmax is part
of 1.2
