+ netdata now has a poweful health monitoring system embedded.
+ Please check the wiki page:
+
+ https://github.com/firehol/netdata/wiki/health-monitoring
+
+ * netdata has badges!

+ https://github.com/firehol/netdata/wiki/Generating-Badges
+
+ * netdata plugins are now written in Python!
+
+ Thanks to the great work of Paweł Krupa (@paulfantom), most BASH
+ plugins have been ported to Python.
+
+ The new python.d.plugin supports both python2 and python3 and
+ data collection from multiple sources for all modules.
+
+ The following pre-existing modules have been ported to Python:
+
+ - apache
+ - cpufreq
+ - example
+ - exim

+
+ The settings transferred are the dashboard theme, the online
+ help status and current pan and zoom timeframe of the dashboard.
+
+ * API improvements:
+
+ - reduction functions now support 'min', 'sum' and 'incremental-sum'.

+ - can now run with command line argument 'without-files'
+ to prevent it from enumating all the open files/sockets/pipes
+ of all running processes.
+
+ - apps.plugin now scales the collected values to match the
+ the total system usage.
+
+ - apps.plugin can now report guest CPU usage per process.
+
+ - repeating errors are now logged once per process.
+
+ * netdata now runs with IDLE process priority (lower than nice 19)
+
+ * netdata now instructs the kernel to kill it first when it starves
+ for memory.
+
+ * netdata listens for signals:
+
+ - SIGHUP to netdata instructs it to re-open its log files
+ (new logrotate files added too).
+
+ - SIGUSR1 to netdata saves the database
+
+ - SIGUSR2 to netdata reloads health / alarms configuration
+
+ * netdata can now bind to multiple IPs and ports.

+ - netdata is now 30% faster
+ - netdata now has a registry (my-netdata dashboard menu)
+ - netdata now monitors Linux Containers (docker, lxc, etc)

+ * netdata now has a CENTRAL REGISTRY !
+
+ The central registry tracks all your netdata servers

+ on all dashboards.
+
+ Every netdata can act as a registry, but there is also
+ a global registry provided for free for all netdata users!

+
+ * Dashboard: improved support for older web browsers
+ and mobile web browsers (thanks to @simonnagl)
+
