In the next version of ESS the underscore will no longer insert assignment by default. Instead you can use `ess-cycle-assign` with the `C-c C-=` binding. This cycles through all assign ops on repeated presses.
To get the previous behaviour, you'll need to opt in by binding "_" to `ess-insert-assign` in your config. This now works with any key of your choice. If binded to ";" for instance, one press will insert assignment, a second press will insert ";".
