2.10.3 fixes TLS connections with masters and agents on reload and “Connection: close” headers with Ruby clients. We’ve also tackled long-term problems with (scheduled) downtimes in HA-enabled cluster environments. 2.10.3 also fixes a problem with time offsets and check results from the future.

Next to the long list of bugfixes, we’ve also improved the documentation with technical concepts on the check scheduler, and a complete overhaul of our development docs for contributors and packagers. We’re currently working on an improved network stack and cluster synchronisation for 2.11, stay tuned.

Thanks to our contributors Edgar, Sven, Leon, Michael, Alex and Max! 2.10.3 is available on packages.icinga.com, Raspbian packages will follow soon. Meanwhile check the changelog for 2.10.3.
