Are we convinced that the ~3 day formula for the Forum is one we want to
stick with ?
With longer cycles and no PTGs in-between, it actually sounds like a good
revisit the "Forum" events to include the "design" and "ops" summits back
into the event.
Perhaps not in the previous format, because it had its flaws, but with
longer cycles I feel
we need something to close that gap.
I've had a lot of discussions and some people that always went to summits
now no longer
attend neither the PTG (because they don't necessarily contribute upstream)
or the Forum
because it's only three days, costs a lot of money, jet lag, there's little
to no ops/design
exposure.. and the talks end up on YouTube anyway.

The complaints about the pace of the development and support cycles are
I won't repeat them here.
While this is not LTS, I can't help but think this is a compromise or a
even though it might not be the intent behind the idea.
Right now we ship a release every 6 months and support each release for 1
means at any given time, there are 3 ongoing "releases", including trunk.
What I'm curious about... is how does this translate into the support cycle
- Pike was released 2017-08-30 and the scheduled EOL is 2018-09-03.
- Ocata was released 2017-02-22 and the scheduled EOL is 2018-02-26.
This can go down a few different ways, I guess we can:
1) Extend the support of a stable release by a full year
This keeps the two rolling stable releases plus the one in development.
Not quite LTS, but you know, it's still 2 years of support instead of
2) Keep the support cycle to a year
This would basically mean that as soon as there is a new release, the
previous one would become EOL ? This is what seems suggested here
and I'm really not confident this would be a great idea. It would force
people to upgrade within weeks after a new release to stay on a
As some others have mentioned in the thread, there are pros and cons to
moving to a
year-long cycle and I think it's great that we are having this discussion
as it will help
us make an informed decision.
It won't be possible to please everyone so leaving this up to the technical
to vote on this matter seems fair.
