This is the fastest version of Pluto ever! This release optimises the overhead of Pluto: the extra time it takes to run a cell (on top of the time that your codes takes). You mostly notice this overhead for large notebooks (>100 cells), and when using @bind.

The overhead in Pluto 0.19.46, compared to the previous version, is:

• 2x lower on a notebook with 100 cells
• 5x lower on a notebook with 200 cells
• 40x lower on a notebook with 500 cells

This means that notebooks with >500 cells are super snappy again! A notebook with 500 cells can do a reactive run in 20ms, this used to take 1 second.

I also tested some old Pluto versions. The overhead in Pluto 0.19.46 is 1.6x lower than any previous Pluto version from the past 2 years.
