Notably, this release also incorporates support for Spark 3.4. On the Flink +front, version 0.14.0 brings several exciting features such as consistent hashing index support, Flink 1.17 support, and U +pdate and Delete statement support. Additionally, this release upgrades the Hudi table version, prompting users to consult +the Migration Guide provided below. We encourage users to review the release highlights(TODO Add link), +[breaking changes](#migration-guide-breaking-changes), and [behavior changes](#migration-guide-behavior-changes) before +adopting the 0.14.0 release. + + + +## Migration Guide +In version 0.14.0, we've made changes such as the removal of compaction plans from the ".aux" folder and the introduction +of a new log block version. As part of this release, the table version is updated to version `6`. When running a Hudi job +with version 0.14.0 on a table with an older table version, an automatic upgrade process is triggered to bring the table +up to version `6`. This upgrade is a one-time occurrence for each Hudi table, as the `hoodie.table.version` is updated in +the property file upon completion of the upgrade. Additionally, a command-line tool for downgrading has been included, +allowing users to move from table version `6` to `5`, or revert from Hudi 0.14.0 to a version prior to 0.14.0. To use this +tool, execute it from a 0.14.0 environment (TODO Check what is this tool).
