*Sourced from [vibur-dbcp's changelog](https://github.com/vibur/vibur-dbcp/blob/master/CHANGELOG).*

> Version 22.2 (05/05/2018) - RECOMMENDED
> =======================================
> * Small performance update.
> 
> Version 22.1 (30/03/2018)
> =========================
> * Adopted changes / improvements from Vibur Object Pool 22.1.
> * Various other small improvements, refactoring, and javadoc updates.
> 
> Version 22.0 (08/02/2018)
> =========================
> * Added logLineRegex configuration option - the application can use this option in conjunction with the
>   logTakenConnectionsOnTimeout option in order to filter the generated stack trace lines.
> * Added takenConnectionsFormatter configuration option - allows the application to implement custom formatting
>   to String of the TakenConnection[] array. Note that the default formatter uses the logLineRegex for filtering.
> * Added GetConnectionTimeout programming hook that is invoked only if the call to DataSource.getConnection()
>   timeouts. The application can use this hook to format and redirect the generated taken-connections log to a different
>   than the usual log location, for example, to Amazon S3. Note that in order to enable the taken-connections tracking
>   the application must set poolEnableConnectionTracking to true. The default hook uses the takenConnectionsFormatter;
>   it can be disabled via setting logTakenConnectionsOnTimeout to false.
> * Fixed a bug in the CloseConnection hook takenNanos parameter calculation, before its value was sometimes incorrect.
> 
> Version 21.3 (28/01/2018)
> =========================
> * Fixed a minor bug in the ResultSet size calculation where the size was sometimes calculated off by one.
> 
> Version 21.2 (29/11/2017)
> =========================
> * Fixed a bug in the implicit closing of the current ResultSet functionality, introduced in version 21.0.
> * Fixed a rarely occurring bug related to the possibility of Statement.getResultSet() to return null.
> 
> Version 21.1 (27/11/2017)
> =========================
> * Added resultSetNanoTime parameter to the ResultSetRetrieval programming hook. This parameter complements the existing
>   resultSetSize parameter and represents the total time taken to iterate over and process the retrieved ResultSet.
> 
> Version 21.0 (22/11/2017)
> =========================
> * Moved the getConnection() retry mechanism (for lazily created connections) from the ConnectionFactory level
>   to the PoolOperations level - this improves the connections reuse in certain situations.
> * Implemented implicit closing of the current ResultSet when the parent Statement is closed.
> * Changed some configuration defaults:
>   a) poolInitialSize 10 -> 5;
>   b) poolMaxSize 100 -> 50;
>   c) reducerTimeIntervalInSeconds 60 -> 30;
>   d) reducerSamples 20 -> 15;
>   e) connectionTimeoutInMs 30_000 -> 15_000;
>   f) acquireRetryDelayInMs 1000 -> 500;
> * Adopted changes / improvements from Vibur Object Pool 21.0.
> * Various other small fixes, refactoring and improvements.
