First beta for the 2.072.0 release.
This release comes with many new phobos features, native TLS support on
OSX, the first bunch of @safety enhancements (try -transition=safe), and
a few smaller language and compiler additions.
This is also the first dmd release to include dub.
Unfortunately we still need to resolve a regression that causes issues
(https://issues.dlang.org/show_bug.cgi?id=16291), you might run into
problems when using std.net.curl.
In case you run into a yet unknown module cycle, this is
likely due to the fixed cycle detection.
We're still working on a -DRT-cyclecheck=printonly switch to allow
making those non-fatal.
