- Update to 1.32.1 (go.d.plugin 0.31.0)
Bug fixes
  * Use the chart id instead of chart name in response to incoming
    cloud context queries
    (gh#netdata/netdata#11898)
  * Fix used_swap alarm calculation
    (gh#netdata/netdata#11868)
  * Initialize enabled parameter to 1 in AlarmLogHealth message
    (gh#netdata/netdata#11856)
- Changes in 1.32.0:
New Cloud backend and Agent communication protocol
This Agent release supports our new Cloud backend. From here, we
will be offering much faster and simpler communication, reliable
alerts and exchange of metadata, and first-time support for the
parent-child relationship of Netdata agents. This is the first
Agent release that allows Netdata Cloud to use the Netdata Agent as
a distributed time-series database that supports replication and
query routing, for every metric!
eBPF latency monitoring, container monitoring, and more
We use eBPF to monitor all running processes, without the
cooperation of the processes and without sniffing data traffic.
This new release includes 13 new eBPF monitoring features,
including I/O latency, BTRFS, EXT4, NFS, XFS and ZFS latencies,
IRQs latencies, extended swap monitoring, and more.
Machine learning (ML) powered anomaly detection
​This release links Netdata Agent with dlib, the popular C++
machine learning algorithms library, which we use to automatically
detect anomalies out-of-the-box, at the edge! Once enabled, Netdata
trains an ML model for every metric, which is then used to detect
outliers in real-time. The resulting "anomaly bit" (where 0=normal,
1=anomalous) associated with each database entry is stored
alongside the raw metric value with zero additional storage
overhead! This feature is still in development, so it is disabled
by default. If you would like to test it and provide feedback, you
can go to the new [ml] section in netdata.conf and set enabled=yes
to turn on anomaly detection. After restarting Netdata, you should
see the Anomaly Detection menu with charts highlighting the overall
number and percent of anomalous metrics on your node. This can be a
very useful single number summary of the state of your node.
New timezone selector and time controls in the user interface
We implemented a new timezone picker and time controls to enhance
administrative abilities in the dashboard.

- Update to 1.31.0 (go.d.plugin 0.29.0)
The v1.31.0 release of Netdata comes with re-packaged and
redesigned elements of the dashboard to help you focus on your
metrics, even more Linux kernel insights via eBPF, on-node machine
learning to help you find anomalies, and much more.
This release contains 10 new collectors, 54 improvements (7 in the
dashboard), 31 documentation updates, and 29 bug fixes.
At a glance
We re-packaged and redesigned portions of the dashboard to improve
the overall experience. Part of this effort is better handling of
dashboard code during installation—anyone using third-party
packages (such as the Netdata Homebrew formula) will start seeing
new features and the new designs starting today. The timeframe
picker has moved to the top panel, and just to its right are two
counters with live CRITICAL and WARNING alarm statuses for your
node. Click on either of these two open the alarms modal.
We've also pushed a number of powerful new collectors, including
directory cache monitoring via eBPF. By monitoring directory cache,
developers and SREs alike can find opportunities to optimize memory
usage and reduce disk-intensive operations.
Our new Z-scores and changefinder collectors use machine learning
to let you know, at a glance, when key metrics start to behave
oddly. We'd love to get feedback on these sophisticated, subjective
new brand of collectors!
Improvements
  * Automatically trigger Helmchart PR on Agent release.
    (gh#netdata/netdata#11084)
  * Implement ACLK env endpoint. (gh#netdata/netdata#10833)
  * Implement new HTTPS client for ACLK. (gh#netdata/netdata#10805)

- Enable additional dependencies (gprc, json, libcurl, libelf,
  libwebsockets, protobuf, snappy, xenstat, yajl)
- Update to v1.28.0 (go.d.plugin 0.26.2)
Release v1.28.0 is a hotfix release to address a deadlock in the
Netdata Agent. If the Agent-Cloud link (ACLK) connection drops and
the Agent fails to queue an on_connect message, it also fails to
properly release a lock in the web server thread.
- Changes in v1.27.0:
The v1.27.0 release of the Netdata Agent brings dramatic
improvements to long-term metrics storage via the database engine,
and new dashboard features like a time & date picker for
visualizing precise timeframes. Two new collectors bring incredible
new value to existing features, including a bit of machine learning
magic.
This release contains 8 new collectors, 1 new notification method
(2 others enhanced), 54 improvements, 41 documentation updates, and
58 bug fixes.

- Update to v1.21.1:
Release v1.21.1 is a hotfix release to improve the performance of
the new React dashboard, which was merged and enabled by default in
v1.21.0.
The React dashboard shipped in v1.21.0 did not properly freeze
charts that were outside of the browser's viewport. If a user who
loaded many charts by scrolling through the dashboard, charts
outside of their browser's viewport continued updating. This excess
of chart updates caused all charts to update more slowly than every
second.
v1.21.1 includes improvements to the way the Netdata dashboard
freezes, maintains state, and restores charts as users scroll.
