I just update to 2020b and notice there are some differences in the new release. First, "Run section" and "Section break" buttons are exchanged. I guess this is due to the usage of "Run section" is more frequenctly than the usage of "Section break". However, this is not compactible to classic editor. "Run section" in classic editor has identical position as "Section break" in live editor, which results in some inconvineince. Second, I cannot clear figures with "Clear all output". I would like to clear all figures and plot new figures in new execution, however, the old figures cannot be removed. No matter of what I do, they are still there. "Clear all output" does work in 2020a. I don't know why it doesn't work in 2020b.

Hi Ryan, can you share the representative code which is causing this issue so that I can reproduce the same issue on my side?

x = 1:256;

figure(1000)

plot(x,x), hold on

legend

Below is the figure I plot and "clear all output" four times. There is supposed to be only one line in the figure.

I found a little work around:

When you put clf (clear current figure - https://ch.mathworks.com/help/matlab/ref/clf.html) before the plot command it works. But in my opinion that's not the way the live editor should work.
