Fixes

Basic lines in XYFrame are no longer drawn with two-sided areas. That means they need to have their fill set as you would a normal line and that they will not do an animated transition into a stacked chart. This was done to resolve a long-term Chrome rendering bug with SVG that couldn't handle single pixel-width perfectly straight areas. It also cured the poor honoring of stroke-dasharray since technically these lines were one on top of the other.
sortO in OrdinalFrame is now passed the column details in new third and fourth parameters so you can set a function to sort based on column data like sortO={(columnAName,columnBName,columnAData,columnBData) => your sorting logic here}
Joy plots can have an ordinal axis if you don't have enough axes in your life already. They're set with an axis property of the summaryType that obeys the same axis settings seen elsewhere in Semiotic.
InteractionLayer should be properly redrawing overlays and interaction regions. It wouldn't update these regions with resizing and also had issues recognizing when NetworkFrame was sending point-based and area-based regions
parentLine will now show up as an attribute of a calculated annotation in situations where that makes sense

Features

ResponsiveFrames will by default debounce by 200ms (they'll wait until there has been no resizing in the last 200ms to fire a resize). You can change this by sending your frame a different debounce property
sortGroups (for Chord diagrams) is honored as a passthrough on networkType
