@JohanMabille not to be merged, just to get the ball rolling. The changelog was dense so I started grouping it by themes.

Also major release because there's an API break

[AntoinePrv]

@serge-sans-paille there are two more improvements to swizzle that I would like to get in if possible.

• Add 8/16 bits AVX2 swizzle #1197 for 8/16 bits (WIP need to fix the errors);
• I have further improvement to the general case for batch_constant;

I can possibly have that within a week. Would that work?

I also have an idea for improving some specific cases on batch_constant but it's a longer shot (possibly very hard under C++11).

THe initial "plan" was to release mid November, but we didn't fix any date, so I think releasing in one week is fine.

Sure, I'll review those.

I am also trying to get the masked_api done asap. I am just busy with deadlines at the moment.
