Kibana 5.2.1 released

Today we're releasing Kibana version 5.2.1, which includes multiple important bug fixes, including a security fix for an issue that can crash the Kibana process.

In all previous versions of Kibana 5, when configured with SSL, Kibana will fail to release file descriptors on certain requests, which over time will build up until the process crashes. Requests that are canceled before data is sent can also crash the process. We've assigned this vulnerability the identifier ESA-2017-02. Kibana 4 is not affected by this vulnerability.

You can get this release at our downloads page. Check out the release notes or the list of bug fixes below.
