As the Sakai community discuss the timing for the release of Sakai 12, Matt Jones of LongSight went back into history and summarized Sakai release activity for the past 5 years to help inform our plans for the Sakai 12 schedule.
I would add to the information that Matt shares below that Sakai 2.9 and Sakai 11 made a lot of forward progress with new/revised UI/UX features and Sakai 2.8, 10, and 12 put a lot of effort into performance, reliability, and scalability and contained less new UI/UX.
I am recording Matt’s notes it here so I don’t lose them. He did a lot of work to get these details. It also shows how much community effort (and Matt Jones work) work goes into Sakai releases.
From Matt Jones:
I looked at all of the past releases, some takeaways from below
- The branch to release for the previous two releases (10 and 11) was about the same, 5 months. 10 cut earlier and was released earlier than 11.
- Even though no release has done branch to (actual) release faster than 5 months, we have planned 2 months for 12
- The time from .0 to .1 for 11 was 1 month, but for previous releases previously was longer, about 3 months (which is our ideal)
- The longest time from branch to release was 2.9, almost 13 months
Sakai 2.8 actually had a Q1 release with Q4 branch. 2.9 was on track for the same but delayed significantly (And ended up with a Q4 release)
Historically there looks to be about a 1-2 month delay from plan to release
