 The polaris-spark project also provides a Spark bundle JAR for the `--jars` use case. The resulting JAR will follow this naming format:
 polaris-spark-<spark_version>_<scala_version>-<polaris_version>-bundle.jar
 For example:
-polaris-spark-bundle-3.5_2.12-1.1.0-incubating-SNAPSHOT-bundle.jar
+polaris-spark-bundle-3.5_2.12-1.2.0-incubating-SNAPSHOT-bundle.jar
 
 Run `./gradlew assemble` to build the entire Polaris project without running tests. After the build completes, 
 the bundle JAR can be found under: plugins/spark/v3.5/spark/build/<scala_version>/libs/.
