Are notebooks v2 available for anyone yet? was curious to try to play around with one

https://observablehq.com/notebook-kit/ I believe yes, for Mac users

The web-based notebooks 2.0 editor is coming next month. Until then you can use Observable Desktop on macOS, or Observable Notebook Kit and your preferred local code editor on any os. (Though there might be some compatibility issues with Windows.) Let us know if you need any help.
