[boost] [release] Request to merge B2

Can I merge the latest, 5.1.0 (a), release of B2 to master at the next opportunity? By next opportunity I mean whenever the release managers think it's appropriate. :-) [a] Release notes: https://github.com/bfgroup/b2/releases/tag/5.1.0 -- -- René Ferdinand Rivera Morell -- Don't Assume Anything -- No Supone Nada -- Robot Dreams - http://robot-dreams.net
