[jira] [Commented] (FLINK-14129) HiveTableSource should implement ProjectableTableSource

    [ https://issues.apache.org/jira/browse/FLINK-14129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17019494#comment-17019494 ] 

Gary Yao commented on FLINK-14129:
----------------------------------

I removed _"HiveTableSource now supports projection."_ from the release notes. Normally, the release notes contain important changes relevant for upgrading from a previous version, such as breaking changes. If you think otherwise, feel free to add the release note back.
