At the same time, a shorter release which leads to upgrade-often pressure but it will have fewer number of changes/features, so make the upgrade easy and longer-release model will have more changes/features that will make upgrade more complex.
I think that was true a few years ago, but I'm not convinced that still holds. We currently have a third of the changes volume we had back in 2015, so a one-year release in 2022 would contain far less changes than a 6-month release from 2015. Also, thanks to our testing and our focus on stability, the pain linked to the amount of breaking changes in a release is now negligible compared to the basic pain of going through a 1M-core deployment and upgrading the various pieces... every 6 months. I've heard of multiple users claiming it takes them close to 6 months to upgrade their massive deployments to a new version. So when they are done, they have to start again. -- Thierry Carrez (ttx)
