Mass does not change with variations of gravity.
Inertial mass is equivalent to gravitational mass.
Therefore, mass does not change with velocity.

So, you admit relativity reduces to verbiage.

The mass m of a body is not constant.

Correct. Heat the body, and its mass increases.

 It varies with the body's velocity, according to the equation:

A bit confused? :-D
Above you said:
Therefore, mass does not change with velocity.
Which is correct.

     m = m0/ √ 1−v2/c2

m is not the mass of the body, it is the "relativistic mass".

 where:
     v      is the magnitude of the velocity of the body
    c      is the speed of light in vacuum
    m0     is the rest mass of the body.

m0 is "the mass of the body".

  The value m is known as the relativistic mass of the body.

Exactly!
So you knew that the obsolete "relativistic mass"
is NOT "the mass of the body".
Why do you then keep repeating the obvious triviality:
"the  mass does not change with velocity" which nobody refutes?
