It's looking very good:
- basically it works very well
- it brings some experimental new features (like http2)
- it is compatible (with backported patches for now) with openssl 1.1.0
- it doesn't crash in some edge cases like #878674 do
I've upgraded it on a very complex project i'm developing - which does
depend on c++ addons and many many various modules, and the
upgrade was seamless.
So all in all i think it's now or never.
Unless someone give me a good reason not to.
