Biwako line covered ?

Hi,

I'm visiting Kyoto for a few days next October.
I read information about Kansai Area passes and I'm not sure if Biwako line is included in the Kansai Area Pass. If I look to the picture of JRWest site it seems so, but reading some other sites and forums it seems the that is is only included in Kansai Wide Area pass. Could you please help me with this ? I'm afraid I'm confused by info that may not be really updated. Thank you.
