The official release announcement with details about these fixes can be
found here:

Beta and stable could be also affected, although I didn't do a detailed
check whether that's the case.
As this introduces Chromium 51 as the dev version, I had to make the
following changes to make it build:
* libexif got removed, so let's do that on our end as well.
See https://codereview.chromium.org/1803883002 for details.
* Chromium doesn't seem to compile with our version of libpng, so let's
resort to the bundled libpng for now.
* site_engagement_ui.cc uses isnan outside of std namespace, so
we're fixing that in postPatch using sed.
I have successfully built all versions on i686-linux and x86_64-linux
and tested it using the VM tests.
