With only one day after the 0.8.3 release 0.8.4 is being released. My deepest apologies because this means there is a bad bug. Admittedly it will only impact a very small amount of users but it was big enough to warrant a new release.
Unfortunately during refactoring of “remove all plugins” code the actual remove code was moved to the wrong place. With 0.8.3 if you say no it will still remove all plugins. This has been corrected and is the only change in 0.8.4.
