-The [tree mark](https://observablehq.com/plot/marks/tree) now supports a **textLayout** option, which defaults to *mirrored*, alternating the orientation of labels for internal (non-leaf) *vs.* external (leaf) nodes. The treeNode and treeLink marks now also support a new **treeFilter** option, allowing these marks to be filtered (without affecting the tree layout).

-[TK Example of mirrored labels in a tree diagram.]
+
-The [tip mark](https://observablehq.com/plot/marks/tip) now automatically sets the pointer-events attribute to *none* when associated with the [pointer transform](https://observablehq.com/plot/interactions/pointer) when the the pointer is not sticky, as when hovering a chart without clicking to lock the pointer. This prevents the tip mark from interfering with interaction on other marks, such as clickable links.
-
-Fix [barycentric interpolation](https://observablehq.com/plot/marks/raster#interpolatorbarycentric-options) outside the convex hull of samples.
+```js
+Plot.plot({
+ axis: null,
+ height: 100,
+ margin: 10,
+ marginLeft: 40,
+ marginRight: 120,
+ marks: [
+ Plot.tree(gods, {textStroke: "white"})
+ ]
+})
+```
-[TK Before and after comparison of barycentric interpolation.]
+The [barycentric interpolator](https://observablehq.com/plot/marks/raster#interpolatorbarycentric-options) now behaves correctly outside the convex hull of samples. The new algorithm (below right) radiates outwards from the hull, ensuring a continuous image; the old algorithm (below left) radiated inwards from values imputed on the frame’s edges, producing discontinuities.
-TK Fix invisible rects with the [auto mark](https://observablehq.com/plot/marks/auto) when both dimensions are ordinal and the **mark** option is set to *bar*.
+
-TK Fix pointer transform on non-faceted marks in faceted plots.
+The [tip mark](https://observablehq.com/plot/marks/tip) now automatically sets the pointer-events attribute to *none* when associated with the [pointer transform](https://observablehq.com/plot/interactions/pointer) when the the pointer is not sticky, as when hovering a chart without clicking to lock the pointer. This prevents the tip mark from interfering with interaction on other marks, such as clickable links.
-TK Fix a regression with the [window transform](https://observablehq.com/plot/transforms/window) when using the *median*, *deviation*, *variance*, or percentile reducer.
+The [auto mark](https://observablehq.com/plot/marks/auto) now renders as a cell, instead of a degenerate invisible rect, when **x** and **y** are both ordinal and the **mark** option is set to *bar*. The [tree mark](https://observablehq.com/plot/marks/tree) no longer produces duplicate tips with the **tip** option. The [rule mark](https://observablehq.com/plot/marks/rule) now respects the top-level **document** option, if any, when using the **clip** option.
-Fix the **clip** option when the [rule mark](https://observablehq.com/plot/marks/rule) is used with a custom **document**. Fix the **tip** option with the [tree mark](https://observablehq.com/plot/marks/tree) to not produce duplicate tips.
+The **title**, **ariaLabel**, and **href** channels no longer filter by default; these channels may now be sparsely defined and the associated mark instance will still render.

+The [pointer transform](https://observablehq.com/plot/interactions/pointer) now handles non-faceted marks in faceted plots. The [window transform](https://observablehq.com/plot/transforms/window)’s *median*, *deviation*, *variance*, and percentile reducers have been fixed.
