amcharts/amcharts4 4.9.20 on GitHub

[4.9.20] - 2020-05-11

hit and up events on nested objects will now respect correct bubbling up order.
If rtl is not set directly on the Label, it will now take rtl value not from its parent but from baseSprite (performance enhancement).
<desc> element with amCharts attribution removed from generated SVG.

Export: PDF export will now fallback to regular fonts if bold fonts don't exist.
Export: Advanced PDF exports with extra content were broken since last release.
Export: Image export was essentially broken in IEs.
options.nonce was not working properly on EDGE.
Event selectedned was not dispatched by Cursor if released outside the chart div and behavior was set to select*.
If all series were removed and then added quickly to the chart with a legend it could result a JS error.
Setting data directly on a series not right after it was created could result series.data array to be shown as empty.
It was impossible to set SwitchButton as active initially.
Fixed snapping cursor to series when data was missing: if series had gaps in data and cursor.snapToSeries was set, the snapping was not working properly.
When adding data to XYSeries which was XYCharScrollbar's series, the raw data was incorrectly modified.
