This release fixes some regressions introduced in OracleDB support in 2.5.11.
Specifically, closing a cursor caused an `ORA-01002` exception to be raised
in some scenarios.

Further fixes include:

 * support for dropping "in use" databases in OracleDB and SQL Server (must disconnect first)
 * corrections in how the last insert ID is fetched on SQL Server
 * re-use of parameters bound to an sqlsrv statement via `bindValue()`
