Hi all,

This is a small follow up of the plans for the next two releases.

I've decided to give the sprint #68 one extra week, changing it to:

 - Feb 11 2019

The reason is that some new features are pending review and would be
nice to have them in version 68.0.  At the same time, we're actively
working on fixing all the known bugs and closing all the issues we can
on GitHub.

This means that the hard feature freeze is in one week!

But, the pure bugfix and stabilization sprint (#69) will now last two
weeks, so the release date of 69.0 (LTS) is unchanged.
