Looking at the release & version bump cycle, some of the steps may be simplified, and hopefully automated:Yes there is and there is quite a bit of history attached to that.
Our governance clearly states that each project is independent, which in this context means is free to release whenever as well as can decide to release outside of Simultaneous Release.
During our initial (Hydrogen, 2014) release, we have had all projects integrating on SNAPSHOTs and the release party was ... not awesome. If you see git tags like "jenkins-controller-bulk-release-prepare-only-2-1", those are from that period. There were multiple technical reasons why it did not go so well.
As a reaction to that, autorelease was created, to have all projects still integrated on SNAPSHOTs, but projects gave up their right to release on their own and instead all projects were release by LFN personnel in one large chunk -- we are still doing this for MSI projects.
The experience of being integrated on SNAPSHOTs was ... not exactly great -- it lead to the creation of validate-autorelease and distribution-check jobs, which gate every patch so that it does not happen to break downstreams.
We have mostly addressed the technical issues by 2017 and started peeling projects away from autorelease with odlparent-2.0.0 (IIRC). Fast forward to today and autorelease does not carry a single kernel project.
With that context, I will never agree to going for "release together" --
that amounts to autorelease hell. I have endured it for years upon years and have toiled sweat and blood to get out of it. I am *NEVER* going back to that, period.
Can we do better than we are doing today?
There are multiple reasons why kernel project releases happen "a few days apart". It is mostly a manual process and you can probably guess whose time is being spent on it.
There is silver lining, though, as Nexus promotions take ~30 minutes for most projects, not 2+ hours like they used to just two months ago. Now if we only had reliable automation taking advantage of that...
