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.
