v0.46.0

v0.46.0 is a monthly release headlined by two major new experimental capabilities:
- [Named slots](https://lexical.dev/docs/concepts/named-slots) - a model that lets a single host element or decorator node own several isolated editable regions inside the host's own `editorState`
- [Shadow DOM](https://lexical.dev/docs/concepts/shadow-dom) - the root element can now be hosted in an open shadow root (or iframe)

This release also includes many other fixes and new features across IME/composition, collaboration, markdown round-tripping, lists, code blocks, links, and mobile keyboards. It is also our first release (other than nightlies) to use NPM Trusted Publishing.

Special recognition for this release goes to @mayrang for doing the majority of the work on both of these new features as well as fixing some tricky IME/composition issues 👏  @levensta has also been doing a fantastic job going through the issue backlog, providing valuable feedback on these bleeding edge features, and identifying long-standing edge cases.

## Breaking Changes

### `lexical` — Node traversal methods no longer accept unsafe type parameters (#8661)

The zero-argument generics on `getParent(OrThrow)`, `getPreviousSibling(s)`, `getNextSibling(s)`, `getChildren`, `getFirstChild(OrThrow)`, `getLastChild(OrThrow)`, `getChildAtIndex`, `getFirstDescendant`, `getLastDescendant`, and `getDescendantByIndex` were implicit unchecked casts — there is no inference site, so any non-base type argument was equivalent to an `as` cast. Each method is now an overload pair: a documented non-generic signature returning the base type (`LexicalNode` / `ElementNode | null`), plus the old generic signature marked `@deprecated`. Code that leaned on contextual-type inference no longer type-checks:

```ts
// Before: compiled (unsound). After: type error.
const node: ParagraphNode | null = $getRoot().getFirstChild();

// Port directly with an explicit cast (no behavior change):
const node = $getRoot().getFirstChild() as ParagraphNode | null;

// Or, better, narrow with a guard:
const node = $getRoot().getFirstChild();
if ($isParagraphNode(node)) { /* node: ParagraphNode */ }
```

Existing `getFirstChild<ParagraphNode>()`-style calls still compile but are now deprecated and will be removed in a future release. This is a types-only change with no runtime impact.

### `lexical` — `$getNearestNodeFromDOMNode(rootElement)` now returns `RootNode` (#8588)

The "selection captured outside of Lexical" mechanism is generalized beyond `DecoratorNode` subtrees: `setDOMUnmanaged(dom, {captureSelection: true})` now marks any subtree (e.g. a `DOMRenderExtension` override or a `getDOMSlot` widget) as selection-captured, and `isDOMCapturingSelection(dom)` walks ancestors so a descendant `<input>` reports as captured. As part of this, the root element now carries a `__lexicalKey_*` stash, so `$getNodeFromDOM` / `$getNearestNodeFromDOMNode` resolve the root element to the `RootNode` instead of `null`. Two call sites become more correct (drop-on-root in clipboard, table-selection→range conversion), but **external callers that relied on `$getNearestNodeFromDOMNode(rootElement)` returning `null` must update**. The internal-only `$isSelectionCapturedInDecorator` was removed.

### `lexical` — `insertNodes` preserves a leading linebreak; managed `<br>`s are now tagged (#8615)

`RangeSelection.insertNodes` now preserves the first `LineBreakNode` when inserting inline content ahead of a block element, instead of silently dropping it. Separately, the reconciler-inserted "managed" line breaks (the otherwise-invisible `<br>`s Lexical adds so the caret can land in empty lines) are now identifiable in the DOM as `<br data-lexical-managed-linebreak="true">` — and, on iOS Safari, an analogous `<img data-lexical-managed-linebreak="true" …>` in some cases. **DOM/HTML snapshot test expectations may need to ignore or expect this attribute.** Closes #3980.

### `@lexical/html` and node extensions — DOMImportExtension rules now register implicitly (#8662) _(experimental)_

The experimental DOM-import pipeline no longer requires you to list a per-package import extension. Each node-providing extension (`RichTextExtension`, `ListExtension`, `LinkExtension`, `TableExtension`, `CodeExtension`) now registers its own import rules, and the standalone `RichTextImportExtension` / `ListImportExtension` / `LinkImportExtension` / `TableImportExtension` / `CodeImportExtension` / `HorizontalRuleImportExtension` become **deprecated aliases that may be removed as early as v0.47.0**. Rules stay inert unless HTML is routed through `ClipboardDOMImportExtension` or `$generateNodesFromDOMViaExtension`; the legacy `importDOM` paste path is unchanged. If you had not adopted these v0.45.0 extensions yet, there is no breaking change.

### `lexical` / `@lexical/yjs` / `@lexical/clipboard` / `@lexical/html` — Named slots (#8603) _(experimental)_

All slot machinery is opt-in and gated (an editor latches `_slotsUsed` on the first `$setSlot`), so editors that never use slots take identical code paths to before. Two changes are observable regardless:

- **`syncLexicalUpdateToYjsV2__EXPERIMENTAL` takes a new `dirtyLeaves` parameter**, inserted between `dirtyElements` and `normalizedNodes` (a slot host's values surface as dirty *leaves*).
- **A `NodeSelection` containing an `ElementNode` now includes that element's children on copy/export** (`$getHtmlContent` / `$generateJSONFromSelectedNodes`). The previous behavior serialized a childless shell, making cut of an element `NodeSelection` silently lossy; partial `RangeSelection`s keep per-child slicing and `excludeFromCopy` children remain excluded.

### `@lexical/link` / `@lexical/list` / `@lexical/react` — Removed exports deprecated since v0.32.1 (#8704)

Exports marked `@deprecated` in v0.32.1 (2025-06-04, >12 months ago) with no Meta-internal consumers are removed:

- `@lexical/link`: `toggleLink` → use `$toggleLink`
- `@lexical/list`: `insertList` / `removeList` → use `$insertList` / `$removeList` (from an update or command listener)
- `@lexical/react`: the `ContentEditable` `Props` type alias → use `ContentEditableProps`

Note: `lexical`'s `$nodesOfType` is intentionally **un-deprecated** (it still has many consumers). The remaining v0.32.1 deprecations that still have internal consumers (`KEY_MODIFIER_COMMAND`, `$wrapNodes`, the `@lexical/table` row/column helpers, etc.) are left for a follow-up.

## New APIs

### `lexical` — `editor.read(mode, fn)` and `EditorReadMode` (#8702)

`read` gains an optional first argument: `'force-commit'` (the default; flushes pending updates first — the previous one-argument behavior), `'pending'` (reads the pending state without flushing — the old `editor.readPending`, now removed), and `'latest'` (reads the committed state without flushing, equivalent to `editor.getEditorState().read(fn, {editor})`). `EditorReadMode` is exported. `readPending` only shipped after v0.45.0, so its removal is not considered a breaking change.

### `lexical` — DOM shadow root support (#8694)

An editor can now mount inside an open shadow tree without losing selection, focus, drag-and-drop, IME composition, or floating-UI behavior. Reads go through platform APIs — `Selection.getComposedRanges`, `Selection.direction`, `ShadowRoot.activeElement`, `Document.caretPositionFromPoint(x, y, {shadowRoots})` — and nine new helpers ship from `lexical`; the light-DOM code paths are unchanged. Follow-ups #8708 (insert nodes at the block cursor inside a shadow root) and #8740 (ignore `beforeinput`/`input` in captured decorators, fixing Firefox 152) complete the surface.

### `lexical` — `onWarn` editor hook (#8644)

`CreateEditorArgs` gains an optional `onWarn?: ErrorHandler` (stored as `_onWarn`, defaulting to `console.warn`), mirroring `onError`. The infinite-update-loop guard's recoverable warning now routes through it (wired end-to-end in #8658), so embedders that bridge reporting to their own telemetry no longer lose this signal to each user's browser console.

### `lexical` — `$config()` accessor-based nominal typing (#8645)

An additive extension of the `$config()` protocol: abstract base classes can declare configuration shared with their subclasses under a `Symbol.for(<ClassName>)` key (resolved by `getStaticNodeConfig`), and accessor-based nominal typing lets subclasses opt into stricter `$config()` checks. No existing node class is changed.

### `@lexical/history` — Cut/paste get their own undo entry (#8649)

Any update tagged `PASTE_TAG` or `CUT_TAG` is now classified as an `OTHER` change inside `@lexical/history`, which keeps it from merging into the **preceding** keystrokes and keeps **following** keystrokes from merging into it. Undoing a short paste (or an iOS autocorrect/prediction) or a cut no longer also undoes the text you typed immediately before it.

### `@lexical/extension` — `SelectBlockExtension` (#8532)

Overrides `SELECT_ALL_COMMAND` so the first invocation selects the nearest block element and the second selects the entire document; a selection already spanning multiple blocks expands straight to the document, and select-all is a no-op when everything is already selected. Includes an opt-in `cascadeSelection` option for nested editors (image captions, etc.) and enables `PreventSelectAllExtension` by default to keep `keydown` from leaking out of `input`/`textarea` elements. (Also introduced `editor.read('pending', …)` via the now-generalized #8702.)

### `@lexical/yjs` / `@lexical/react` — Collaborative cursors via the CSS Custom Highlight API (#8550)

Remote collaborators' selections are now painted with the widely-supported CSS Custom Highlight API; the error-prone absolutely-positioned overlay remains only as a fallback. The remote caret is still rendered as a positioned element. Closes #4457, #5837.

### `@lexical/utils` — `dedupeSelectionRects` (#8709)

A new exported helper that drops zero-area rects and any rect that contains another (with 1px tolerance) from `Range.getClientRects()`, fixing the duplicate/over-bright and spurious extra-wide fake-selection rects WebKit produces on some blocks. It is wired into `positionNodeOnRange`, so every fake-selection consumer (`markSelection`, `selectionAlwaysOnDisplay`, the extension) gets clean rects. Addresses #7106, #7492.

### `@lexical/code-core` — `escapeWithArrows` (#8393)

`CodeIndentExtension` gains an `escapeWithArrows` option (default `false`): when a code block is the terminal node and the caret is at the end of its text, pressing the arrow keys creates a new paragraph and moves the caret into it. New `$onEscapeDown` / `$onEscapeUp` helpers back it in `@lexical/utils`. Closes #7912, #4685, #5968.

### `@lexical/react` — Self-contained `LexicalErrorBoundary` (#8720)

`LexicalErrorBoundary` no longer wraps `react-error-boundary` (the dependency is dropped) and gains an optional `fallback` prop — omit it for the default message, or pass `fallback={null}` to render nothing. Its public type is unchanged, so it remains usable as the `ErrorBoundary` prop of `RichTextPlugin` / `PlainTextPlugin`.
