ZCS 7.1 (DoubleHelix)
A release is a highly coordinated and planned effort - lots of things to check, double-check, and update
Heck here's an outstanding issue:
Bug 58717 - Unexpected EOF in ZCS 7.1 Ubuntu8_64 FOSS

Basically what was going to be 7.0.2 became 7.1 - it's like a normal maintenance release plus the groundwork for future encryption and authentication features - which warranted an increment of the minor version instead of micro.
In hindsight perhaps we could have called it 7.2 to avoid confusion with 7.0.1, but most can figure out that versioning follows our standard Major.Minor.Micro concept - DoubleRainbow puns aside.
