Re: [DISCUSS] Stabilizing 4.0

Thank you all those who responded.

One potential way we could speed up sussing out issues is running regular "Bug 
Bashes" with the help of the user community. We could periodically post stats 
and recognize folks who contribute the most issues. This would help gain 
confidence in the builds we're putting out there. Thoughts?

It is a good catch, Mick. :-)

I will triage those tickets to be sure that our view of things is accurate.

That's a very good point. At the risk of saying sthg silly or being
captain obvious, as I am not familiar with the project dynamics, there
should be a periodic 'backlog triage' or similar. Otherwise we'll have
the impression we have just a handful of pending issues while another
10x packet is hiding but we didn't notice yet.

That is a good finger in the air starting point imo. We'd have to adjust
the backing filter to reflect exactly what we want. But we have the data
and a graph report available already at hand which is good :-)

It would be nice to have a graph on our weekly status of the number of
issues reported on 4.0. I feel like having a visual representation of the
number of bugs on 4.0 over time would be really helpful to give us a
feeling of the progress on its stability.
It might also be interesting to see which components are the most affected
to help us to determine where we should increase the testing.

We also created a confluence doc for a test plan with major areas that

I had a quick look at the JIRAs associated with the different areas of the
plan and a lot of them appear to be blocked. I believe that most people are
unsure of what or how to test things and want to get some feedback before
starting to add tests.
It would be great if in the coming weeks we can all help to unblock those
tickets by clarifying what needs to be done on each of them. I guess that
none of us have a clear picture but sharing ideas would definitely help.

Your suggestion makes sense to me.Hopefully releasing 4.0-beta will also be
a strong sign that the project is still active.
