chore(release): 31.0.0 [skip ci]

# [31.0.0](v30.2.0...v31.0.0) (2021-06-29)

### Bug Fixes

* **xy:** render gridlines behind axis  ([#1204](#1204)) ([38ebe2d](38ebe2d)), closes [#1203](#1203)
* memory leak related to re-reselect cache ([#1201](#1201)) ([02025cf](02025cf))
* **partition:** getLegendItemsExtra no longer assumes a singleton ([#1199](#1199)) ([100145b](100145b))

### Features

* **annotations:** option to render rect annotations outside chart ([#1207](#1207)) ([4eda382](4eda382))
* **heatmap:** enable brushing on categorical charts ([#1212](#1212)) ([10c3493](10c3493)), closes [#1170](#1170) [#1171](#1171)
* **xy:** add onPointerUpdate debounce and trigger options ([#1194](#1194)) ([a9a9b25](a9a9b25))

### BREAKING CHANGES

* **xy:** the `PointerOverEvent` type now extends `ProjectedValues` and drops value. This effectively replaces value with `x`, `y`, `smVerticalValue` and `smHorizontalValue`.
