3.5.0

A note about rendering order of series, which might be interpret as a bug or breaking change since this release

This is not really a breaking change, but might be interpret like that. In #794 we've fixed the wrong order of series, thus now all series will be displayed in opposite order (they will be displayed in order of creating now; previously they were displayed in reversed order).

To fix that, just change the order of creating the series (thus instead of create series A, then series B create series B first and then series A) - see #812.

Fixed

• Screenshot output missing piece on bottom right (see #798)
• Overlapped line chart show wrong color order when hover (see #794)
• Price line label show on both axis (see #795)

Undocumented breaking changes

We know that some of users probably used some hacky-workarounds calling internal methods to achieve multi-pane support. In this release, to reduce size of the bundle we dropped out a code for pane's separator (which allows to resize panes).

As soon this workaround is undocumented and we don't support this feature yet - we don't bump a major version. But we think it's better to let you know that it has been changed.

Development

• Dropped support NodeJS < 12.18
• Migrated from TSLint to ESLint (see #314)
• Migrated from clean-publish to in-house script to clear package.json (see #474)
