@movq Yes. The author tries hard not to break existing code, but apparently he did this time. In his defense, it’s not an official release, I just updated to master. Which is exactly what I always did in the past as there are no real versions (I even think that in one ticket he wrote years ago that master is always stable). That has finally changed a year ago, though: https://github.com/rivo/tview/releases/tag/v0.42.0
