### Breaking changes

The deprecated interfaces `blockAtHeight`, `visualLineAtHeight`, `viewportLines`, `visualLineAt`, `scrollPosIntoView`, `scrollTo`, and `centerOn` were removed from the library.

All decorations are now provided through `EditorView.decorations`, and are part of a single precedence ordering. Decoration sources that need access to the view are provided as functions.

Atomic ranges are now specified through a facet (`EditorView.atomicRanges`).

Scroll margins are now specified through a facet (`EditorView.scrollMargins`).

Plugin fields no longer exist in the library (and are replaced by facets holding function values).

This package no longer re-exports the Range type from @codemirror/state.

This package no longer exports the `Range` type (now from @codemirror/state).

### Bug fixes

Fix a bug where zero-length block widgets could cause `viewportLineBlocks` to contain overlapping ranges.

### New features

The new `perLineTextDirection` facet configures whether the editor reads text direction per line, or uses a single direction for the entire editor. `EditorView.textDirectionAt` returns the direction around a given position.

`rectangularSelection` and `crosshairCursor` from @codemirror/rectangular-selection were merged into this package.

This package now exports the tooltip functionality that used to live in @codemirror/tooltip.

The exports from the old @codemirror/panel package are now available from this package.

The exports from the old @codemirror/gutter package are now available from this package.
