[boost] Yap review extended until Feb 19th

14 Feb 2018

      Dear Boost community,

The review of Zach Laine's Yap library was supposed to conclude today,
Wednesday February 14th. To give more people the chance to review the
library, and since there's no review scheduled directly after Yap,
the review period will be extended until (and including) Monday February
19th.

Thanks,
Louis Dionne
