v0.48.0 is a maintenance release focused on bug fixes across Markdown, tables, lists, links, and selection. It's headlined by a fix for a v0.46.0 regression that broke native text drag-and-drop (#8842) and a couple of notable security hardening fixes. It also adds a handful of new features, including an MdastHtmlExtension with examples for authoring custom Markdown constructs (collapsibles, kbd, alerts, footnotes), a customizable Yjs shared-type root name for collaborative editing, and new table row manipulation helpers.

New APIs & Features

• @lexical/table — Added $moveTableRow for reordering table rows, plus the previously missing $unmergeCellNode export (#8833)
• @lexical/yjs / @lexical/react — The Yjs shared-type root name is now customizable, so Lexical can share a Yjs document with other content that uses a different root key (#8841)
• @lexical/extension / @lexical/mdast — Added MdastHtmlExtension and Markdown custom-construct examples (collapsible sections, kbd, alerts, footnotes) demonstrating how to extend the Markdown ↔ mdast pipeline. See the Markdown & mdast serialization guide (#8826)

Notable Fixes

Drag & drop (fix for v0.46.0 regression)

• Don't cancel dragover for text drags, so native drops work again (#8842)

Security

• LinkNode.sanitizeUrl() now fails closed on unparseable URLs, preventing a potential XSS vector (#8846)
• Fixed a serialize-javascript dependency vulnerability (#8803)

Markdown & code

• Roundtrip overlapping inline formats correctly through mdast/Markdown (#8825)
• Force re-tokenization after an async language load so highlighting appears once the grammar is ready (#8830)

Tables

• Auto-scroll while drag-selecting cells past the visible edge (#8822)
• Enable table copy in read-only mode (#8845)

Lists & character limit

• Backspace at the start of a list item now outdents or converts to a paragraph (#8829)
• Merge adjacent OverflowNodes in useCharacterLimit (#8831)
• Count block separators when wrapping character-limit overflow (#8840)

Links & selection

• Disable link opening for disabled autolinks (#8839)
• Skip scrollIntoViewIfNeeded when the selection rect is above the editor, fixing a Safari RTL caret jump (#8848)
