osquery 2.3.2 incorrectly reports an empty value for `platform` on CentOS6 hosts. We added a workaround to properly detect platform in Kolide, and also [submitted a fix](https://github.com/facebook/osquery/pull/3071) to upstream osquery.
In an effort to provide a more resilient web server, timeouts are more strictly enforced by the Kolide HTTP server (regardless of whether or not you're using the built-in TLS termination). If your Kolide environment is particularly latent and you observe requests timing out, contact us at [help@kolide.co](mailto:help@kolide.co).
* Harden TLS server settings.
For customers using Kolide's built-in TLS server (if the `server.tls` configuration is `true`), the server was hardened to only accept modern cipher suites as recommended by [Mozilla](https://wiki.mozilla.org/Security/Server_Side_TLS#Modern_compatibility).
* Improve the mechanism used to calculate whether or not hosts are online.
Previously, hosts were categorized as "online" if they had been seen within the past 30 minutes. To make the "online" status more representative of reality, hosts are marked "online" if the Kolide server has heard from them within two times the lowest polling interval as described by the Kolide-managed osquery configuration. For example, if you've configured osqueryd to check-in with Kolide every 10 seconds, only hosts that Kolide has heard from within the last 20 seconds will be marked "online".
Customers running Kolide behind a web balancer lacking support for websockets were unable to use the distributed query feature. Also, in certain circumstances, Safari users with a self-signed cert for Kolide would receive an error. This release add a fallback mechanism from websockets using SockJS for improved compatibility.
Previously Kolide was determing platform based on the OS of the system osquery was built on instead of the OS it was running on. Please note: Offline hosts may continue to report an erroneous platform until they check-in with Kolide.
* Support MySQL client certificate authentication. More details can be found in the [Configuring the Kolide binary docs](https://docs.kolide.co/kolide/1.0.1/infrastructure/configuring-the-kolide-binary.html)
