Review comment (suggestion):
Sorry for not noticing this before, but as mentioned in the comment on lines 59-60, you should increment the `Settings.VERSION` and use the value here.

Everything else is good, just missing this now.

Code after:
                new V(1, new BooleanSetting(false))
        ));
        s.put("backgroundOperations", Settings.versions(
                new V(1, new EnumSetting<>(K9.BACKGROUND_OPS.class, K9.BACKGROUND_OPS.WHEN_CHECKED_AUTO_SYNC)),
                new V(83, new EnumSetting<>(K9.BACKGROUND_OPS.class, BACKGROUND_OPS.ALWAYS))
        ));
        s.put("changeRegisteredNameColor", Settings.versions(
                new V(1, new BooleanSetting(false))
        ));
        s.put("confirmDelete", Settings.versions(
                new V(1, new BooleanSetting(false))
