### Agent 20.13.0

* Datafeed v2 now properly supports the Presence events.
* Fixed bug where the endpoint to share an article could bypass the DLP checks.
* New metrics are now available in the logs to help the troubleshooting (such as memory/CPU usage, health check statuses, cache, client pool, or thread pool usage, in/out response time, etc.).
* In the configuration file, the keystore password can now be encrypted.
* Fixed a bug of excessive token storing duration in cache, causing occasional 401s when trying to read datafeed v2 once expired.
