Netdata 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.

v.1.21.1 includes improvements to the way the Netdata dashboard freezes, maintains state, and restores charts as users scroll.
