Sourced from @​lexical/code's releases.

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.

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.

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 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 guide and the "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 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 and Listeners.
