[boost] [1.59] Boost 1.59 schedule?

Hi, The official release schedule at http://www.boost.org/development/index.html seems to indicate we're now really close to the first beta of Boost 1.59, yet I don't see much activity in the mailing list and, for instance, the release notes are almost empty now: https://github.com/boostorg/website/blob/master/feed/history/boost_1_59_0.qb... Is this schedule still valid? Thank you, Joaquín M López Muñoz Telefónica
