Hi, Devs, Many questions from the open source community are actually caused by the behavior changes we made in each release. So far, the migration guides (e.g., https://spark.apache.org/docs/latest/sql-programming-guide.html#migration-guide) were not being properly updated. In the last few releases, multiple behavior changes are not documented in migration guides and even release notes. I propose to do the document updates in the same PRs that introduce the behavior changes. If the contributors can't make it, the committers who merge the PRs need to do it instead. We also can create a dedicated page for migration guides of all the components. Hopefully, this can assist the migration efforts.
Thanks, Xiao Li
