The State of Elyria - July 2017 under "Estimated schedule of development," shows the development schedule. A Year of Foundation also address some things on what they have in development in-depth under "2018, A Year of Progress."
Please note the schedule they posted does not guarantee it will be out on the time listed, it is around when they'll begin development.
To that end, below is an approximate schedule - not of when we expect the work to be complete - but when we expect to be under active development toward a particular deliverable or milestone. Providing a timeline in this format allows us to have an open, transparent, candid conversation about what and when we're working on something, while still giving us the freedom to make changes sprint-to-sprint and change the dates of our internal milestones to suit our development needs.
For easy reading Q3, and Q4 means "Quarter 3 and Quarter 4." T1, T2, and T3 means "trimester 1, 2, or 3," and implies a 4-month window. S1 and S2 means "semester 1 or 2" and implies a six-month window of time.
