+### Download Information

([asc](https://www.apache.org/dist/incubator/hudi/0.5.1-incubating/hudi-0.5.1-incubating.src.tgz.asc),
[sha512](https://www.apache.org/dist/incubator/hudi/0.5.1-incubating/hudi-0.5.1-incubating.src.tgz.sha512))
+ * Apache Hudi (incubating) jars corresponding to this release is available [here](https://repository.apache.org/#nexus-search;quick~hudi)
+
+### Release Highlights
+* Dependency Version Upgrades
+    * Upgrade from Spark 2.1.0 to Spark 2.4.4
+    * Upgrade from Avro 1.7.7 to Avro 1.8.2
+    * Upgrade from Parquet 1.8.1 to Parquet 1.10.1
+* **IMPORTANT** This version requires your runtime spark version to be upgraded to 2.4+.
+* Hudi now supports both Scala 2.11 and Scala 2.12, please refer to [Build with Scala 2.12](https://github.com/apache/incubator-hudi#build-with-scala-212)
to build with Scala 2.12.
+Also, the packages hudi-spark, hudi-utilities, hudi-spark-bundle and hudi-utilities-bundle
are changed correspondingly to hudi-spark_{scala_version}, hudi-spark_{scala_version}, hudi-utilities_{scala_version},
hudi-spark-bundle_{scala_version} and hudi-utilities-bundle_{scala_version}.
+Note that scala_version here is one of (2.11, 2.12).
+* With 0.5.1, we added functionality to stop using renames for Hudi timeline metadata operations.
This feature is automatically enabled for newly created Hudi tables. For existing tables,
this feature is turned off by default. Please read this [section](deployment_link), before
enabling this feature for existing hudi table.
+To enable the new hudi timeline layout which avoids renames, use the write config "hoodie.timeline.layout.version=1".
Alternatively, you can use "repair overwrite-hoodie-props" to append the line "hoodie.timeline.layout.version=1"
to hoodie.properties. Note that in any case, upgrade hudi readers (query engines) first with
0.5.1-incubating release before upgrading writer.
 
 Review comment:
   we probably need to update configurations page as well? were there other configs added
in 0.5.1?  @bvaradar ?
