I am a part of the public beta but never installed El Capitan for a variety of reasons. I'd like to install El Capitan sometime this week so that everything will be compatible with IOS 9 releasing tomorrow (e.g. iCloud Notes). So, I'll be upgrading from Yosemite directly to the El Cap GM. Assuming this is the only GM between now and the end of the month, will I have to update El Cap on 9/30 or will the software releasing 9/30 be identical? Also, will I automatically receive the first maintenance release, 10.11.1, per usual in the app store when it is available?
