Differences in shading between 4.2.1 and 4.3?

Hello everyone.

I converted my project from 4.2.1 to 4.3, and at first, everything looks fine. But when I build lighting in 4.3, my floor changes. It has less reflections and I think the normal map is less noticeable too. Here are some screenshots:

(The deformations are because of a heat shader I made).

Anyone know what could be the reason?

Here are the release notes:

There are a couple of lighting and reflection updates in there. Like different resolution SSR, skylight with indirect lighting etc…
