Hi Deepti, Regarding the life cycle for 1.x versions, 1.x will receive its last bugfix version upon the release of 1.(x+2), e.g, 1.16 will receive its last bugfix version upon the release of 1.18. Given that Flink release a minor version every 6 months, this means each minor version will receive bugfixes for about 1 year.
One possible exception is the last version of the 1.x series. There has been discussion on making it an LTS version, but no consensus has been reached yet. Most likely 1.20 will be the last version of 1.x series and would be an LTS version. For Java 17 support, it is supported in Flink 1.18 but annotated as "experimental" so far. I'm not sure on the meaning of "experimental" as well. My personal understanding is that it lacks massive production adoption yet, hence "experimental". But a few companies have already adopted Java 17 in production, including ByteDance as mentioned by Xiangyu.

Do we have any defined end of life dates for 1.16, 1.17 and 1.19? Also is 1.18 will be the last minor release for 1.x series? Also what do you mean by experimental support of Java 17? Will Java17 is supported by Flink community with Flink 1.18? Can we use this combination in our commercial product release?
