• [BREAKING] expansion and improvement of the temporal axis.values config array. (see #303, #299, 9c56102)
• fix a long-standing bug where series hover points were cut off at plot edges (#301)
• {select: {over: true}} ability to choose whether .u-select is placed inside .u-over as previously, or .u-under. this is now relevant since .u-over is no longer overflow: hidden and it's possible for a programatically-set selection inside .u-over to visually overflow the plot bounds (a consequence of fixing #301)
• series.auto: false can be used to exclude a series' data from being considered when auto-ranging its y scale
• a bunch of fixes for plots with no datapoints, or single datapoint
• new demo: https://leeoniya.github.io/uPlot/demos/y-shifted-series.html
• much-improved line-smoothing demo using Centripetal Catmull-Rom Spline algo
