In general, MySQL depends on an exact version of Boost. We're actively
extending Boost.Geometry, so we're quite tied to the version we pick for
each release. Even if MySQL compiles with a newer version of Boost, each
upgrade of Boost causes a number of tests results to change ever so
slightly. E.g., a line from A to B may become a line from B to A, etc.
This means that even if everything is correct, a number of tests will
Boost 1.61.0, in particular, contains too many bugs. We gave up trying to
use it in development and jumped straight from 1.60.0 to 1.62.0 for MySQL
Boost 1.62.0 is not bug free either, but we managed to get around the
issues that bothered us, and we're submitting patches upstream to make
sure it's fixed in future versions.
