   An update that fixes four vulnerabilities is now available.

Description:

   This update for netdata fixes the following issues:

   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!
