v0.42.0 is a monthly release with a huge number of fixes and features from a lot of new contributors. The most notable fixes are related to tables, links, extensions, and markdown. @lexical/eslint-plugin is now fully compatible with eslint 9+. The production builds are also now generated in an ascii-only format which may considerably reduce memory usage in some deployment environments.
Breaking Changes
Prism highlighting extracted from @lexical/code #8198
Prism highlighting now lives in @lexical/code-prism and the Prism related functionality in @lexical/code is now deprecated. Transitionally, there is a @lexical/code-core package which has the implementation of Lexical's code functionality without a Prism dependency.
Experimental hasFitNestedTables has been moved to the playground #8210
Due to its experimental nature and incomplete implementation, the in-progress hasFitNestedTables functionality has been moved to the playground
New APIs
lexical - $copyNode + LexicalNode.resetOnCopyNodeFrom & NodeState resetOnCopyNode
After $copyNode is used it now calls copiedNode.resetOnCopyNodeFrom(originalNode) which will reset every NodeState that has resetOnCopyNode: true in its configuration. Subclasses can override this method to reset other "ephemeral" state such as whether a ListNodeItem is checked or not.
Note that this does not influence serialization or copy and paste operations, it only affects calls to $copyNode.
@lexical/utils - $insertNodeIntoLeaf
The current behavior RangeSelection.insertNodes can split an inline ElementNode (e.g. a LinkNode) when inserting content, even if that content is also inline and could be a child of the given node. $insertNodeIntoLeaf is now provided to insert a node without splitting any containing nodes.
