Hi all,

thanks a lot to everyone involved in this release :)
I've already been using the 8.6 branch for some weeks now because it's
so much faster than 8.5 (~30% speedup for us) -- this is a solid release
indeed.

Now I'm waiting for the new version to appear in opam so that I can
switch away from the 8.6.dev branch... ;)

Kind regards,
Ralf
