That's my understanding, and I would advocate strongly to keep the 4.0 release schedule as planed originally.

The 3.9 one should really be an additional "out of schedule" release not impacting any other releases.

The plan sounds good to me. I suppose that we will follow our regular
cadence for 4.0 and release it four months after 3.9 (in November?). Is
this correct?

Hi all,

Thanks Colin, yes go ahead.

As we are now past code freeze I would like to ask everyone involved
in a
KIP that is not yet complete, to verify if what landed on the 3.8
branch
needs to be reverted or if it can stay. Additionally, I'll be pinging
KIPs
and Jira reporters asking for their status as some Jiras seem to have
all
related GitHub PRs merged but their status is still Open or In
Progress.
I'll be checking all the open blockers and check if they are really a
blocker or can be pushed.


Regarding timeline, I'll attempt to generate the first RC on Wednesday
or
Thursday, so please revert any changes you deem necessary by then. If
you
need more time, please ping me.

Best,

Hi all,

We have had many delays with releases this year. We should try to get
back
on schedule.

I agree with the idea that was proposed a few times in this thread of
drawing a line under 3.8 now, and doing a short 3.9 release. I
posted a
3.9
release plan here:
https://cwiki.apache.org/confluence/display/KAFKA/Release+Plan+3.9.0

I think we could start doing RCs for 3.8.0 as early as next week.
There
are a few things that need to be reverted first (anything related to
KIP-853 or KIP-966).

Josep, if you agree, I will update KIP-1012 to reflect that these
things
are landing in 3.9 rather than 3.8. And we can start doing all the
normal
release stuff. The main blocker JIRA I'm aware of is KAFKA-16946,
which
is
a very simple fix.

best,
Colin

I think Jose, also mentioned that it won't be ready for
v3.8.0
(but he

confirm this). My question now would be, given that it
seems
we

a v3.9.0, do you think it's important to include

Hi Josep

For KIP-966, I think Calvin had mentioned he won't
complete
in
v3.8.0.

For unclean leader election, all we need is this PR:
https://github.com/apache/kafka/pull/16284
For this PR, I think it needs one more week to be
completed.

Thanks.

Hi all,

We are now really close to the planned code freeze
deadline
(today
EOD).
According to KIP-1012 [1] we agreed to stay in the 3.x
branch
until we
achieve feature parity regarding Zookeeper and KRaft.
The
two main
KIPs
identified that would achieve this are: KIP-853 [2]
and
KIP-966
[3].
At the moment of writing this email both KIPs are not
completed. My
question to the people driving both KIPs would be, how
much
more
time do
you think it's needed to bring these KIPs to
completion?

- If the time needed would be short, we could still
include
these
2 KIPs
in
the release.
- However, if the time needed would be on the scale of
weeks, we
should
continue with the release plan for 3.8 and after start
working on
the 3.9
release.

What are your thoughts?

looks
ready

several

is relatively straightforward and not risky. Also
the

Your proposal sounds good to me. I suspect that
will
be
doing
feature
development for KIP-853 past the feature
freeze and
code
freeze
date.
Maybe feature development will be finished
around
the end
of June.

I'll make sure to cherry pick commits for
KIP-853
to
the 3.8
branch
once we have one.
