PR incoming, @AnthropicAI? 👀
Joking aside, Claude Code being able to even understand our codebase to write complex features is awesome!

Introducing lasso selection!
A more freeform selection method when you need the extra precision, or the versatility.
Pick from the toolbar, or use Option/Alt+Drag.

We're now supporting manual elbow arrow editing!
If the default auto-routing algorithm doesn't work for your diagram, you can create new segments and position them where you want.
Implemented by @mtolmacs 💜

Small improvements to frames!
First, deleting a frame from now on doesn't delete its children. This way it's easier to remove content from a frame.
The children are selected upon frame deletion, so if you want to remove both you can just hit Delete twice.

You can now link canvas elements together, or share a link to specific content with others!
You can link elements from the hyperlink popup. To copy a link instead, use the context menu or the command palette.

Flowcharts!
Keyboard shortcuts to create flowcharts more easily!
Use Cmd/Ctrl+Arrow to create nodes. Hold Cmd/Ctrl while pressing Arrow repeatedly to create multiple nodes at once.

We've shipped new fonts!
Revitalized our handdrawn font, swapped sans and monospace fonts, and added a heading font.
Many thanks to @mrazator! 💜

Continuing with the text wrapping improvements, you can now set the text width even during creation. Simply drag with the text tool.
There's a minimum distance before the text enters the wrapped mode so there aren't false positives.
