[DISCUSS] Official policy for release maintenance

[Ismaël Mejía]

​Following my previous question at user@ and by Fabian’s suggestion I moved
the discussion here.

Flink has been growing steadily, and many organizations are asking the
question of how are the releases of flink maintained in the long term, so
maybe it is a good idea to decide and make public the official policy
around this.

I looked at the wikipedia article on Flink and it implied that releases are
maintained from the last two major versions which I don’t think is the
case, I have the impression that currently only the latest major release is
maintained, however I didn’t find any official documentation around this.

What do you think guys? Has this been discussed before? Maybe this is a
good moment to decide this, if we haven’t.

Regards,
Ismaël

Hey Ismael,

thanks for bringing this up. I think it's a very important to
communicate this on the project web page.

There was a discussion [1] about adopting time based releases were
most committers and contributors agreed to support the last two major
versions, e.g. the latest stable and the previous stable (1.2 and 1.1
for our current release).

It would be nice to formulate this officially somewhere with more
details, e.g. previous major release gets critical bug fixes only. The
time based releases Wiki page [2] does not do this currently.

Is that in line with the Wikipedia article? It could be that the
wording was/is confusing.

I'll update the Wikipedia article and include the details into our wiki.

In addition, what do you think about adding the "update guarantees" on the
download or FAQ page?

Thanks Robert, I would like that!

+1 for adding something to the Downloads page. Maybe add it to the FAQ
and link from the downloads page or the other way around? I don't know
what's better.
