This release adds a couple of minor new features and improves multithreaded
locking behavior in ConnectionPool. There should be no backwards-
compatibility concerns.
Features
* Full support for column_start, column_finish, column_count, and
column_reversed parameters in contrib.stubs
* Addition of an include_ttl parameter to ColumnFamily fetching
methods which works like the existing include_timestamp parameter.
Bug Fixes
* Reduce the locked critical section in ConnectionPool, primarily to
make sure lock aquisition time is not ignored outside of the pool’s
timeout setting.
