cx_Oracle 7.1 is now released. The biggest enhancement for this release is for session pools. Specifically, a session callback may now be specified when a pool is created. This allows an application to improve performance by reducing the number of round trips to the database needed in order to set session state.

A number of smaller enhancements and bug fixes were also made. See the [full release notes](https://cx-oracle.readthedocs.io/en/latest/releasenotes.html#version-7-1-february-2019) for all of the details.

cx_Oracle 7.0 is now released. The biggest enhancements for this release come with support for Oracle Client 18 libraries. This allows support for new features such as [call timeouts](https://cx-oracle.readthedocs.io/en/latest/connection.html#Connection.callTimeout) and a preview of [SODA](https://cx-oracle.readthedocs.io/en/latest/soda.html) (Simple Oracle Document Access).

A number of smaller changes were also made to improve the experience of using cx_Oracle. These include re-enabling the pool pinging functionality for Oracle 12.2 and higher to handle classes of connection errors such as resource profile limits; improved error messages when a feature requires a particular version of Oracle Client libraries or Oracle Database; better handling of objects when the connection that created them is closed; better handling of connections when the pool that created them is destroyed; etc.

For those upgrading from cx_Oracle 6, note that variables bound to DML returning statements now return an array when calling [getvalue()](https://cx-oracle.readthedocs.io/en/latest/variable.html#Variable.getvalue) and that using a connection as a context manager now closes the connection when the block is completed.

This release adds support for grouping notifications to [subscriptions](https://cx-oracle.readthedocs.io/en/latest/connection.html#Connection.subscribe) and adds support for getting notifications when AQ messages are available to be dequeued. Support was also added for timed waits when [acquiring sessions](https://cx-oracle.readthedocs.io/en/latest/module.html#cx_Oracle.SessionPool) from a session pool and for setting the values of the timeout and maximum lifetime attributes of a pool when it is created. Cursors can now be used as context managers and a number of other enhancements and bug fixes were made.
