Improvements:

      fragmentation of free memory pages
    + The unbound collector module was completely rewritten, in Go
  * Collector improvements:
    + We rewrote our web log parser in Go, drastically improving
      its flexibility and performance
    + The Kubernetes kubelet collector now reads the service
      account token and uses it for authorization. We also added a
      new default job to collect metrics from
      https://localhost:10250/metrics
    + Added a new default job to the Kubernetes coredns collector
      to collect metrics from
      http://kube-dns.kube-system.svc.cluster.local:9153/metrics
    + apps.plugin: Synced FRRouting daemons configuration with the
      frr 7.2 release
    + apps.plugin: Added process group for git-related processes
    + apps.plugin: Added balena to the container-engines
      application group
    + web_log: Treat 401 Unauthorized requests as successful
    + xenstat.plugin: Prepare for xen 4.13 by checking for check
      xenstat_vbd_error presence
    + mysql: Added galera cluster_status alarm
  * Metrics database:
    + Netdata generates alarms if the disk cannot keep up with
      data collection
  * Health:
    + Fine tune various default alarm configurations
    + Update SYN cookie alarm to be less aggressive
    + Added support for IRC alarm notifications
Bug fixes:
  * Prevented freezes due to isolated CPUs
  * Fixed missing streaming when slave has SSL activated
  * Fixed error 421 in IRC notifications, by removing a line break
    from the message
  * proc/pagetypeinfo collection could under particular
    circumstances cause high CPU load. As a workaround,
    we disabled pagetypeinfo by default
  * Fixed incorrect memory allocation in proc plugin’s
    pagetypeinfo collector
  * Eliminated cached responses from the postgres collector
  * rabbitmq: Fixed "disk_free": "disk_free_monitoring_disabled"
    error
  * Fixed Apache module not working with letsencrypt certificate
    by allowing the python UrlService to skip tls_verify for http
    scheme
  * Fixed invalid spikes appearing in certain charts, by improving
    the incremental counter reset/wraparound detection algorithm
  * Fixed issue with unknown variables in alarm configuration
    expressions always being evaluated to zero
  * Fixed issue of automatically picking up Pi-hole stats from a
    Pi-hole instance installed on another device by disabling the
    default job that collects metrics from http://pi.hole
