The JDK 8 development schedule was divided into a sequence of milestone cycles, most six to eight weeks in length, with builds occuring roughly once each week. There were no formal beta or early-access releases. Major features and other potentially-destabilizing changes were targeted for integration early in a specific milestone.

Here is the milestone schedule, with the features integrated in each cycle:

Milestone definitions

The early development milestones (M1–M6) were date-driven; they came and went regardless of the state of the release. Most later milestones are condition-driven; we intended to reach the goal of the milestone by the given date, but if we didn't then we declared the milestone at a later date and adjusted any following milestones as necessary. Here are definitions of the later milestones, in the order in which they occur:
