Fold and unfold since version 1.5.1

[itzikd15]

Hello, I am trying to upgrade from version 1.5.1 but since version 1.5.2 and forward i cant use the session.unfold() / session.foldAll()

i can see in the changes over here:
d5d6f9a

that editSession doesn't support folding any more

how can i fold all the lines in my code and also how can i unfold?

thanks!

The folding interface was restored in version 1.15.3.
