## Migration Guide
+With 0.11.0, we have added a checksum mechanism for validating the
`hoodie.proerties`, which introduces a new table version, `4`.
+ Whenever a Hudi job is launched with this release on a table with older
table version, an upgrade step is executed automatically to upgrade the table
to table version `4`.
+ This automatic upgrade step happens just once per Hudi table as the
hoodie.table.version will be updated in property file after upgrade is
completed.
+ Similarly, a command line tool for Downgrading (command - downgrade) is
added if in case some users want to downgrade Hudi
+ from table version `4` to `3` or move from Hudi 0.11.0 to pre 0.11.0. This
needs to be executed from a 0.11.0 hudi-cli binary/script.
+
### Bundle usage updates
- Spark bundle for 3.0.x is no longer officially supported. Users are
encouraged to upgrade to Spark 3.2 or 3.1.
