There is a breaking change for Flink SQL after fixing FLINK-20539
Can we also have it mentioned in release notes?

In jira's for FLINK-20539 there is a filled release notes field.

May be we should also check in case there are some more jira issues targeted to 2.2.0 with not empty release notes field
