+ New configuration option `temperature.sensors_chipsets` - [BREAKING (?)] `sensors` sub-call won't have its STDERR redirected to `/dev/null` anymore. - It allows occurring errors to be shown, instead of silently fail in temperature computations. - This could happen if the user specifies (a) wrong chipset identifiers. - Errors/warnings may still be silenced at the Archey level using the `suppress_warnings` configuration option. - This new feature could not be unit-tested as it completely relies on the `sensors` sub-call, to which we pass chipsets identifiers.
