Release 0.3.0-incubating

Release 0.3.0-incubating (docs)​

This is the third official Apache release for Apache XTable (Incubating), an incubating project under the Apache Software Foundation. Apache XTable™ (Incubating) facilitates omni-directional interoperability across data processing systems and query engines by allowing users to convert between open table formats without the need to rewrite any data files. Currently, Apache XTable™ (Incubating) supports the open-source table formats for Apache Hudi, Apache Iceberg, and Delta Lake.
