Fost 5 release 5.16.12.45005 now out

The tags were pushed a few days ago now.

There is one potentially breaking change in the updates to the nullable type. Now that std::optional is in C++17 it seems sensible to move towards that. The new nullable implementation is a wrapper around std::experimental::optional, but retains the old nullable methods as well, but marks them as deprecated. It also adds a couple of methods that are in the upcoming std::optional but aren't in std::experimental::optional.

As part of the nullable changes we also stopped bringing in the std::rel_ops namespace. This could be a breaking change where you've been inadvertently relying on it for implementations of things like operator !=.

We've also improved the error handling in the fostlib::utf::save_file such that it should now throw if there is a problem saving the file. There's also a new file based log sink called panoptes which features built-in file rotation.

We didn't do the changes to the fost-orm library this time around, but expect them for the next release.
