Flink 1.11.4 release? And usual plan for maintenance etc

[Adam Roberts]

Hey everyone, a few short questions please - is there an expected release
date/target for 1.11.4 please? I ask as I've noticed a couple of dependency
upgrades that I'd really like to pick up if possible, instead of moving to
Flink 1.12 or 1.13 due to the existing Flink jobs we have.



My second question is related...is the 1.11.x line still actively
maintained?



Is it just receiving fixes and patches or enhancements too?



And once 1.13 is released, might the 1.11x release line be restricted to
just patches?



Curious how things are done, obviously if there is documentation I've just
missed out please send that my way.



Thanks!

Hi Adam,

Currently there are no concrete plans for the 1.11.4 release. Usually the
community creates a new release after enough fixes have been merged or if
there is enough demand for it. We have indeed accumulated 35 fixes for
1.11.4 already which could justify a new release. Which fixes do you need
in particular?

1.11.x is still actively maintained. The community's update policy is a bit
hidden here [1]. In a nutshell, the community supports the latest two major
releases with bug fixes for critical issues. Consequently, we are currently
supporting 1.11.x and 1.12.x.

Usually enhancements are only backported if they don't change Flink's
behaviour and if there is demand for it. So usually, this does not happen.

Once Flink 1.13 is released, Flink 1.11.x won't be maintained anymore by
the community. This means that problems won't be fixed in the 1.11.x
release branch.

Hey Till, all - thanks for the information, very useful to know.

So the JIRAs in particular are for upgrading the version of Jackson
https://issues.apache.org/jira/browse/FLINK-21020, and there's another for
Netty as well https://issues.apache.org/jira/browse/FLINK-21019 but
admittedly I'm not sure how applicable/easy the former is to do against the
1.11.x stream.

Of course, if we can pick up any bug fixes and potentially security fixes
along the way that would be great - 35 fixes sounds good to me.

*Just out of interest, if you had to guess when do you think 1.13 would be
released?*

Thanks again,

The 1.13 feature freeze is scheduled for the end of march, and the
release can be expected to happen between 2-4 weeks after that.
