The choice of rendering engine usually depends on the scenario, for example, benefit from the low memory cost, SVG Rendering Engine is suitable for mobile device, or the case that many ECharts instances exists in a single page, while the Canvas Rendering Engine is suitable for big data rendering or when visual effects required. Canvas Rendering Engine is default rendering engine. See zrender.
[+] Published Sunburst Chart to visualize hierarchical data efficiently with excellent interactions. See [examples] and (excellent) and docs。

3.8.0, the content in
libdirectory is the same as the content in
srcdirectory (both are ES Module), which may not compatible with the old verisons of node and webpack. So rollback to commonJS format in
3.8.0, the source code in
srcconstains global variable
__DEV__(which prints dev helper info for echarts users). To get the declaration of the global variable, users should include
echarts/src/config.jsmanually or make some settings in
rollup(Check custom build tutorial please), which is not backward compatible. So we have removed
__DEV__from the codes in
3.8.2. If dev helper info is required, use codes in
echarts/src/echarts.js(the same as
3.8.0) does not include util methods, which used to be mounted on it. Now util methods are listed in
echarts/src/exportand mounted on
echarts/echarts*.js. But it is not backward compatibility, so we have rollbacked to mount them on

textStyle exist in echarts option everywhere, for example, series-bar.label.normal.textStyle, xAxis.axisLabel.textStyle. It seems that some of them are to deep and verbose. So we removed the level of
textStyle to flatten them. That is, previous
axisLabel.textStyle.fontSize is modified to
v3.7. Of course, the previous style is compatible all the same. Those options are flattened:
[+] Supported minInterval on time axis (that is, axis.type is
'time'), and supported maxInterval on value axis (that is axis.type is
'value'). So that it is enabled to controll the precision of label when data zooming.
