I'm very excited about this release. It allows the module to provide custom settings per library+chart type. An example of this is that when a user uses Highcharts and selects a bar/column type, they now have an option (in Views or the Chart Field) to check a box to enable "stackLabels" (the total of a stacked column shown at the top of the column). There are two other Highcharts options taking advantage of this: the option for solid gauge charts and the ability to use "colorAxis" on pie/donut charts,.
Reverted one bug fix from 1.0.0-alpha4, which seems to have broken automatic login after installation is complete (see #3520014: Flush all caches once done).
This is a release candidate for the next minor version (feature release) of Drupal 11. Release candidates are not supported for production sites, but they are intended for widespread testing in preparation for the upcoming stable release. More information on release candidates.
