Update chrono, smart_ptr, serialization, math, log, phoenix, multiprecision, asio from develop.
Ignore mistaken commit.

I was testing the commit script locally and accidentally run in
production mode, and it incorrectly reverted some old changes because it
had an incomplete copy of events. I undid the change, but there's a
chance someone grabbed so merging it in without changes so they'll get a
smooth update.
