• Use response.headers.append('Set-Cookie', ...) instead of response.headers.set('Set-Cookie', ...) to not overwrite cookies set by other middleware/handlers

• Explicitly set context.formData in all POST cases, even when the request body is invalid

• Always delete the original session ID when it is regenerated with the deleteOldSession option. Intermediate IDs are never saved to storage, so they can't be deleted.

Generated from commits between v4.2.1 and HEAD

• Fix CommonJS/cjs builds https://github.com/tldraw/tldraw/pull/7282

• Added data-dragging attribute to drag handle elements to track drag state.

• Added data-dragging attribute to drag handle elements to track drag state.

• Added data-dragging attribute to drag handle elements to track drag state.

• Added data-dragging attribute to drag handle elements to track drag state.

• Ensure enableClickSelection works regardless of the openOnClick option by always registering the link click handler plugin.

• Skip the table of contents update logic during IME input method composition to avoid interference with input.

• Fixed trailing and leading whitespace handling in markdown serialization for inline marks

• Add 'mentionSuggestionChar' to allowedAttributes for Markdown serialization in multi-mention setups. The attribute is only serialized when it differs from the default '@' character, keeping markdown output clean for single-mention users.

• 1. Added an optional createCustomHandle callback to ResizableNodeView, allowing developers to fully customize resize handles. When provided, it replaces the default handle creation and bypasses the built-in positionHandle logic, giving complete control over markup, styling, and positioning while preserving backward compatibility.
  2. Removed predefined inline styles from the wrapper element to better support dynamic alignment. This eliminates the need for !important overrides in user styles.
  3. Added an editor update event listener to dynamically attach or remove resize handles based on the editor’s editable state. The implementation tracks the previous editable state to avoid unnecessary re-renders.
