+netdata (1.10.0) - 2018-03-27
+
+ Please check full changelog at github.
+ https://github.com/netdata/netdata/releases
+ 
+
+netdata (1.9.0) - 2017-12-17
+
+ Please check full changelog at github.
+ https://github.com/netdata/netdata/releases
+ 
+
+netdata (1.8.0) - 2017-09-17
+
+ This is mainly a bugfix release.
+ Please check full changelog at github.
+ 
+
+netdata (1.7.0) - 2017-07-16
+
+ * netdata is still spreading fast
+
+   we are at 320.000 users and 132.000 servers
+
+   Almost 100k new users, 52k new installations and 800k docker pulls
+   since the previous release, 4 and a half months ago.
+
+   netdata user base grows at about 1000 new users and 600 new servers
+   per day. Thank you. You are awesome.
+
+ * The next release (v1.8) will be focused on providing a global health
+   monitoring service, for all netdata users, for free.
+
+ * netdata is now a (very fast) fully featured statsd server and the
+   only one with automatic visualization: push a statsd metric and hit
+   F5 on the netdata dashboard: your metric visualized. It also supports
+   synthetic charts, defined by you, so that you can correlate and
+   visualize your application the way you like it.
+
+ * netdata got new installation options
+   It is now easier than ever to install netdata - we also distribute a
+   statically linked netdata x86_64 binary, including key dependencies
+   (like bash, curl, etc) that can run everywhere a Linux kernel runs
+   (CoreOS, CirrOS, etc).
+
+ * metrics streaming and replication has been improved significantly.
+   All known issues have been solved and key enhancements have been added.
+   Headless collectors and proxies can now send metrics to backends when
+   data source = as collected.
+
+ * backends have got quite a few enhancements, including host tags and
+   metrics filtering at the netdata side;
+   prometheus support has been re-written to utilize more prometheus
+   features and provide more flexibility and integration options.
+
+ * netdata now monitors ZFS (on Linux and FreeBSD), ElasticSearch,
+   RabbitMQ, Go applications (via expvar), ipfw (on FreeBSD 11), samba,
+   squid logs (with web_log plugin).
+
+ * netdata dashboard loading times have been improved significantly
+   (hit F5 a few times on a netdata dashboard - it is now amazingly fast),
+   to support dashboards with thousands of charts.
+
+ * netdata alarms now support custom hooks, so you can run whatever you
+   like in parallel with netdata alarms.
+
+ * As usual, this release brings dozens of more improvements, enhancements
+   and compatibility fixes.
+
+
+netdata (1.6.0) - 2017-03-20
+
+ * birthday release: 1 year netdata
+
+   netdata was first published on March 30th, 2016.
+   It has been a crazy year since then:
+
+     225.000 unique netdata users
+             currently, at 1.000 new unique users per day
+
+      80.000 unique netdata installations
+             currently, at 500 new installation per day
+
+     610.000 docker pulls on docker hub
+
+   4.000.000 netdata sessions served
+             currently, at 15.000 sessions served per day
+
+      20.000 github stars
+
+             Thank you!
+          You are awesome!
+
+ * central netdata is here
+
+   This is the first release that supports real-time streaming of
+   metrics between netdata servers.
+
+   netdata can now be:
+
+   - autonomous host monitoring
+     (like it always has been)
+
+   - headless data collector
+     (collect and stream metrics in real-time to another netdata)
+
+   - headless proxy
+     (collect metrics from multiple netdata and stream them to another netdata)
+
+   - store and forward proxy
+     (like headless proxy, but with a local database)
+
+   - central database
+     (metrics from multiple hosts are aggregated)
+
+   metrics databases can be configured on all nodes and each node maintaining
+   a database may have a different retention policy and possibly run
+   (even different) alarms on them.
+
+ * monitoring ephemeral nodes
+
+   netdata now supports monitoring autoscaled ephemeral nodes,
+   that are started and stopped on demand (their IP is not known).
+
+   When the ephemeral nodes start streaming metrics to the central
+   netdata, the central netdata will show register them at "my-netdata"
+   menu on the dashboard.
+
+   For more information check:
+   https://github.com/netdata/netdata/tree/master/streaming#monitoring-ephemeral-nodes
+
+ * monitoring ephemeral containers and VM guests
+
+   netdata now cleans up container, guest VM, network interfaces and mounted
+   disk metrics, disabling automatically their alarms too.
+
+   For more information check:
+   https://github.com/netdata/netdata/tree/master/collectors/cgroups.plugin#monitoring-ephemeral-containers
+
+ * apps.plugin ported for FreeBSD
+
+   @vlvkobal has ported "apps.plugin" to FreeBSD. netdata can now provide
+   "Applications", "Users" and "User Groups" on FreeBSD.
+
+ * web_log plugin
+
+   @l2isbad has done a wonderful job creating a unified web log parsing plugin
+   for all kinds of web server logs. With it, netdata provides real-time
+   performance information and health monitoring alarms for web applications
+   and web sites!
+
+   For more information check:
+   https://github.com/netdata/netdata/blob/master/collectors/python.d.plugin/web_log#web_log
+
+ * backends
+
+   netdata can now archive metrics to `JSON` backends
+   (both push, by @lfdominguez, and pull modes).
+
+ * IPMI monitoring
+
+   netdata now has an IPMI plugin (based on freeipmi)
+   for monitoring server hardware.
+
+   The plugin creates (up to) 8 charts:
+
+    1. number of sensors by state
+    2. number of events in SEL
+    3. Temperatures CELCIUS
+    4. Temperatures FAHRENHEIT
+    5. Voltages
+    6. Currents
+    7. Power
+    8. Fans
+
+   It also supports alarms (including the number of sensors in critical state).
+
+   For more information, check:
+   https://github.com/netdata/netdata/tree/master/collectors/freeipmi.plugin
+
+ * new plugins
+

+   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'.
+
+   - netdata now offers a multi-threaded and a single threaded
+     web server (single threaded is better for IoT).
+

+     contributed to the overal efficiency.
+
+ * netdata now has a CENTRAL REGISTRY !
+
+   The central registry tracks all your netdata servers
+   and bookmarks them for you at the 'my-netdata' menu
+   on all dashboards.
+
+   Every netdata can act as a registry, but there is also
+   a global registry provided for free for all netdata users!
