v6.0.1

Features

• Markdown and KaTeX now render in arrow and summary labels, including when an arrow label is edited.

Bug Fixes

• Moving a node into itself or one of its own children is now rejected instead of corrupting the map.
• Initializing a map twice in quick succession no longer duplicates its behaviour.
• Unfinished typing in the outliner is no longer lost when the map updates elsewhere or when you undo.
• Choosing "link" repeatedly no longer creates duplicate arrows, and clicking away cancels an unfinished link.
• Removing an arrow or summary no longer leaves it selected, so delete and rename target the right element.
• Box selection stays aligned when the map auto-scrolls to its edge.

Behavior Changes

• Some operation methods now return undefined when a call is cancelled, with no change to runtime behaviour.
