v0.45.0

v0.45.0 is a monthly release with several breaking changes around selection and reconcile semantics, a major new experimental `DOMImportExtension` API for composable HTML import that replaces `importDOM`, a generalized `DOMSlot` and DOM render override surface, new `HistoryExtension` ergonomics (`canUndo`/`canRedo` signals, `maxDepth`), notable reconciler/selection performance work, and a wide range of bug fixes across IME, mobile keyboards, list/code/table editing, and markdown round-tripping.

## Breaking Changes

### `lexical` — Shadow root inclusion in `$getReconciledDirection` (#8479)

`$getReconciledDirection` now walks through shadow roots when resolving the reconciled `dir` attribute on a node, so nested ShadowRoot-style elements (e.g. tables) inherit direction consistently with regular elements. Callers that relied on direction inheritance stopping at shadow roots will need to update.

### `lexical` / `@lexical/rich-text` — Backspace at block start preserves the current block (#8493)

Pressing Backspace at the start of a non-empty block previously merged the current block into the previous block, which discarded the current block's type/format. The new behavior merges the previous block's children into the current block instead, preserving the current block's type (heading, list item, quote, etc.). A new `$mergeBlockBackward` helper on `RangeSelection` is exposed for custom command handlers that want the same behavior.

### `lexical` — Selection adjustment in `removeFromParent` callers (#8501)

`LexicalNode.replace`, `insertBefore`, `insertAfter`, and related callers that move a node between parents now correctly adjust the current selection to follow the moved node instead of leaving the selection pointing at the (now empty) original slot. This may change selection state observed by transforms or update listeners that previously relied on the stale offsets.

### `@lexical/markdown` — Apply markdown shortcuts on composition-committed triggers (#8503)

Markdown shortcuts (e.g. `*`, `_`, `~`) typed via IME composition now trigger after the composition is committed, not just on raw `beforeinput`. This fixes shortcuts being silently dropped during Japanese / Korean / Chinese input but may also fire shortcuts in some flows that previously didn't.

### `@lexical/extension` / `@lexical/rich-text` / `@lexical/plain-text` — `NormalizeInlineElementsExtension` (#8497)

`registerRichText` and `registerPlainText` now register a transform that removes empty inline elements (e.g. `LinkNode`, formatted `TextNode` wrappers with no children) instead of leaving them in the tree. The transform is also exported as `NormalizeInlineElementsExtension` from `@lexical/extension` for use with extension-based setups. Editors that intentionally kept empty inline wrappers will need to disable the extension or override the transform. See [Included Extensions](https://lexical.dev/docs/extensions/included-extensions).

### `lexical` / `@lexical/extension` / `@lexical/rich-text` / `@lexical/plain-text` — `NormalizeTripleClickSelectionExtension` (#8520)

The "triple-click selects the whole paragraph including the trailing newline" normalization has moved out of `LexicalEvents` and into a new `NormalizeTripleClickSelectionExtension` registered by both rich-text and plain-text. The core `LexicalEditor` no longer performs this normalization on its own, so editors that bypass `registerRichText` / `registerPlainText` (or the equivalent extensions) need to register the extension explicitly to keep the previous behavior. See [Included Extensions](https://lexical.dev/docs/extensions/included-extensions).

### `lexical` / `@lexical/html` / `@lexical/selection` / `@lexical/utils` / `@lexical/playground` — Generalized `DOMSlot` and DOMRenderExtension override surface (#8519)

`DOMSlot` is now generalized so child slots can be expressed for arbitrary DOM containers (not just the direct child element), and `$createDOM`, `$updateDOM`, `$exportDOM`, `$getDOMSlot` etc. all flow through the new override surface. The previously-exported `AutocompleteNode` in the playground has been replaced by a `VisibleLineBreakExtension` that demonstrates the new override surface, and `markSelection` in `@lexical/utils` has been rewritten on top of the generalized slot API. Custom nodes that override `getDOMSlot` to return a non-element wrapper now have a real way to express that. See the [DOMRenderExtension](https://lexical.dev/docs/serialization/dom-render) docs.

## New APIs

### `@lexical/html` — `DOMImportExtension` *(experimental)* (#8528)

A new `DOMImportExtension` replaces the legacy node-class `importDOM` static method with a composable middleware-style API. Rules declare a CSS-selector-style matcher, an optional schema for child handling, and a `DOMImportFn` that builds Lexical nodes from the matching DOM. Many helpers ship alongside it: `$distributeInlineWrapper`, `ImportSession`, `DOMPreprocessFn` for source-specific cleanup (Word, VS Code, etc.), and full TypeScript types for rules, captures, and contexts. A new `dev-examples/dom-import` showcase wires it up to a Word/VS Code paste flow. The legacy `importDOM` continues to work; new code can opt in to `DOMImportExtension` for richer composition and explicit ordering. The companion `ClipboardDOMImportExtension` (in `@lexical/clipboard`) routes `text/html` pastes through the new pipeline. See the [DOMImportExtension](https://lexical.dev/docs/serialization/dom-import) guide and the ["Migrating from `importDOM`"](https://lexical.dev/docs/serialization/dom-import#migrating-from-importdom) section.

### `@lexical/html` / `@lexical/playground` — Conditional DOM render overrides (#8575)

`domOverride` now supports `disabledForEditor` and `disabledForSession` predicates so render overrides can be conditionally skipped on a per-editor or per-session basis (e.g. only apply during export, or only when a feature flag is on). Useful when one extension provides multiple overrides whose applicability depends on context that isn't known at registration time. See the [DOMRenderExtension](https://lexical.dev/docs/serialization/dom-render) docs.

### `lexical` — `ElementNode` import/export of `data-lexical-indent` (#8536)

`ElementNode` now uniformly imports and exports the `data-lexical-indent` attribute so any subclass round-trips its indent level through HTML without having to override `exportDOM` / `importDOM` (fixes the long-standing #7729 regression around indented headings/paragraphs).

### `lexical` — Infinite recursion detection in update listeners (#8542)

Update listeners and update transforms that re-trigger themselves are now caught by a runtime guard that throws a descriptive error after a configurable number of nested updates, instead of hanging the tab. See [Updates](https://lexical.dev/docs/concepts/updates) and [Listeners](https://lexical.dev/docs/concepts/listeners).

### `@lexical/history` — `canUndo` / `canRedo` ReadonlySignals (#8465)

`HistoryExtension`'s output now exposes `canUndo` and `canRedo` as `ReadonlySignal<boolean>`s so toolbar buttons can subscribe directly without polling `historyState` or duplicating the priority/state bookkeeping. See [Extension Signals](https://lexical.dev/docs/extensions/signals).

### `@lexical/history` — `maxDepth` option (#8537)

`HistoryExtension` accepts a new `maxDepth` option that bounds the undo stack. Older entries are evicted FIFO when the depth is exceeded. See the new ["Tuning HistoryExtension for memory and long sessions"](https://lexical.dev/docs/concepts/history#tuning-historyextension-for-memory-and-long-sessions) docs.

### `@lexical/markdown` — `$convertSelectionToMarkdownString` (#8395)

Counterpart to `$convertToMarkdownString` that serializes only the current selection (or any caller-provided range) to a markdown string, useful for "copy as markdown" toolbar actions and for selection-scoped AI prompts.

### `lexical` / `@lexical/list` — `$setFormatFromDOM` (#8460)

A new `$setFormatFromDOM` helper extracts `text-align` / `dir` from a DOM element and applies it to an `ElementNode`. `ListItemNode.importDOM` now uses it to correctly import alignment for list items pasted from external sources.

### `@lexical/list` — `ListNode.createListItemNode` (#8427)

`ListNode` exposes a `createListItemNode` factory that is now used by children-normalization, so `ListNode` subclasses can supply a custom `ListItemNode` subclass without monkey-patching the normalizer.

### `@lexical/rich-text` — `escapeFormatTriggers` on `RichTextExtension` (#8383)

`RichTextExtension` now accepts an `escapeFormatTriggers` config (a `ReadonlySignal<EscapeFormatTriggerConfig>`) that opts text-format escape behavior in/out per trigger (`enter`, `click`, `arrow`, `space`, `tab`). With it enabled, typing at the boundary of a formatted text node "escapes" the active format (bold, italic, code, etc.), matching the typing experience in Google Docs / Notion. Disabled by default. See [Included Extensions](https://lexical.dev/docs/extensions/included-extensions).

### `@lexical/extension` / `@lexical/playground` — `ClickAfterLastBlockExtension` (#8549)

New `ClickAfterLastBlockExtension` inserts a fresh paragraph when the user clicks below the last block (and places the caret in it), so single-block editors and short documents don't strand the user with no easy way to start a new line.

### `@lexical/code-prism` / `@lexical/code-shiki` — `null` `Tokenizer.defaultLanguage` (#8553)

`Tokenizer.defaultLanguage` may now be `null` to indicate that code blocks without an explicit language should round-trip through markdown without injecting a default language tag (e.g. ```` ```javascript ````). Preserves CommonMark's "no fence info" form on export.

### `@lexical/code-core` / `@lexical/code-shiki` / `@lexical/code-prism` — Outdent space-indented code lines (#8445)

Shift+Tab in a code block now correctly outdents space-indented lines (not just tab-indented), respecting the tokenizer's configured indent width.

### `@lexical/react` — Optional async `onClose` for `LexicalTypeaheadMenuPlugin` (#8489)

`LexicalTypeaheadMenuPlugin`'s `onClose` may now return a `Promise`, useful for handlers that need to await network or animation work before tearing down the menu.

### `@lexical/clipboard` — `GetClipboardDataExtension` export (#8431)

`GetClipboardDataExtension` is now exported from `@lexical/clipboard` for use as a peer dependency from custom clipboard handlers.

### `@lexical/website` — Server-rendered "Copy page" Markdown button (#8570)

Every docs page now has a server-rendered "Copy page as Markdown" button (and a matching `?raw` URL) so AI assistants and humans can grab the raw markdown without scraping the rendered HTML.
