No..

Barely any change in public capacity. I can’t tell you what to do with your own channels, but it seems very premature to force close everything. Still no real world examples of a successful exploit and unless you have a horrible channel partner who is working hard to build a program to steal your sats, it’s much more likely that some solution will outpace any potential problems.

I’m far from an expert though - I’d take cues from people much smarter and more experienced.
