I'm +1 on the change, but only after the Alpine image maintainers update latest to point to 3.5 (see docker-library/official-images#2489 (comment)).

@tianon now the alpine:latest is same as alpine:3.5 :)

I successfully build-tested 7.1/alpine, 7.0/alpine, and 5.6/alpine -- hopefully Travis shows us that the rest are OK too. 🙈

[PeterDaveHello]

@tianon looks great! I forget to check its dependencies, sorry for that!

Revert incoming in #360 -- see docker-library/golang#131 (comment) for more details.

@tianon @PeterDaveHello i'll try to build php7.1 with alpine3.5 and it works. See repo

Yep, in alpine 3.5 are:

Switch from OpenSSL to LibreSSL

they are notice about that on release note page

Now there is no difference between build with openssl or libressl, all sources placed in /usr/include/openssl/.

---

If someone does not read realese notes - this is a huge problem. But OpenSSL does not fix bugs for a long time. At the same time, LibreSSL is kept up to date and evolving.

Mb we can add/create new tag for Alpine 3.5?
