Leveldb update: Plans for 1.53?

[Robert Backhaus]

There is a difference between 1.52 and 1.53 regarding the boost_chrono lib.
The next version of the port I maintain, net-p2p/bitcoin, will use
boost_chrono. It's not a big issue - If we stay on 1.52 I'll have to add a
reference to LIBS; if we move to 1.53, I won't.

I'd just like to know what I'll have to do.

So, what are the plans for boost 1.53?
