At the moment(13.12.2015) Debian 8(jessie) is in revision 2.0, e.g. CD-1 for amd64 architecture is named debian-8.2.0-amd64-CD-1.iso. How to understand revisions for Debian stable? For example does debian-8.2.0-amd64-CD-1.iso contain updated software versions compared to debian-8.0.0-amd64-CD-1.iso only in security-wise? Also in feature-wise? When does stable version of Debian move from one revision to another? As I understand, the feature-, bug-, and security-updates are also released in between the revision and revision is simply a snapshot of the stable release at certain point in time?
