It is not usual to summarize v1. The idea is explain just the changes.

Nitpick: usually, the info about version changes doesn't follow that
style (uppercase v, point, number => lowercase v, number).

If you keep a loop, then what Brian already said.
But out of curiosity, as mentioned, the other alternative is filling
params32 with -1 when defining it:
GLint params32[16] = { [0 ... 15] = -1 };
Any disadvantage over the loop?
