Hi Martijn,
Thanks for the pointer; that makes sense – many (most?) projects only provide
fixes at the current release (apart for exception circumstances – possibly some
high priority security fixes) ; I am curious why Flink fixes 2 streams of code.
One thing that I wondered about is me is the use of the word ‘support’. In
previous open source projects we have been keen to stress that the open source
community does not provide support, in line with the Apache 2 license which
talks of the code being supplied as-is with no warrantee. What do you think
about not using the word support in case it is misleading?
Kind regards, David.

Subject: [EXTERNAL] Re: Backport strategy
Hi David,
The policy is that the current and and previous minor release are
supported, and it's documented at
https://flink.apache.org/downloads/#update-policy-for-old-releases
One of the reasons for decoupling the connectors from Flink is that it
could be possible to support older versions of Flink as well. That
depends of course on the complexity of the backport etc which is a
case-by-case situation.
Best regards,
Martijn
