Silverstone 2012 has working DRS ?

Hi,
Does anyone know if the S397 Silverstone 1.60 track has been recently updated and includes DRS ?

 

Was there a time where it had no DRS zones?

 

Thanks for the informative reply, peterchen !
Just did a stint to find out that the DRS in the S397 1.6 version is on for most of the track, so useless.
Any idea if I could repair this ? (before I start sifting through old not applicable anymore info/new info) ?
The RaceRfactor_Silverstone_2013_v10 version has correctly working DRS zones but I was hoping for a more recent version.
They both share the problem of pit lane entrance not being clearly marked so easy to get a stop/go/drivethrough.
