============================================================================
The old preferences had errors and warnings ON by default and allowed to opt-out.
It was not possible to separate errors/warnings intended for users from those intended for developers.
The new version has developer errors and warnings OFF by default. User intended ones are ON.
It is possible to opt-in for developer errors and warnings from the preferences dialog.
As developer errors and warnings are NOT translated, if opting-in, they won't be localised.
User errors and warnings should be translated. If they are not, it is a bug.
