+## [Release 0.5.2-incubating](https://github.com/apache/incubator-hudi/releases/tag/release-0.5.2-incubating)
([docs](/docs/0.5.2-quick-start-guide.html))
+
+### Download Information
+ * Source Release : [Apache Hudi(incubating) 0.5.2-incubating Source Release](https://www.apache.org/dist/incubator/hudi/0.5.2-incubating/hudi-0.5.2-incubating.src.tgz)
([asc](https://www.apache.org/dist/incubator/hudi/0.5.2-incubating/hudi-0.5.2-incubating.src.tgz.asc),
[sha512](https://www.apache.org/dist/incubator/hudi/0.5.2-incubating/hudi-0.5.2-incubating.src.tgz.sha512))
+ * Apache Hudi (incubating) jars corresponding to this release is available [here](https://repository.apache.org/#nexus-search;quick~hudi)
+
+### Migration Guide for this release
+ * Support for overwriting the payload implementation in `hoodie.properties` via specifying
the `hoodie.compaction.payload.class` config option. Previously, once the payload class is
set once in `hoodie.properties`, it cannot be changed. In some cases, if a code refactor is
done and the jar updated, one may need to pass the new payload class name.
+ * Write Client restructuring has moved classes around ([HUDI-554](https://issues.apache.org/jira/browse/HUDI-554)).
Package `client` now has all the various client classes, that do the transaction management.
`func` renamed to `execution` and some helpers moved to `client/utils`. All compaction code
under `io` now under `table/compact`. Rollback code under `table/rollback` and in general
all code for individual operations under `table`
+ * Simplify `HoodieBloomIndex` without the need for 2GB limit handling. Prior to spark 2.4.0,
each spark partition has a limit of 2GB. In Hudi 0.5.1, after we upgraded to spark 2.4.4,
we don't have the limitation anymore. Hence removing the safe parallelism constraint we had
in` HoodieBloomIndex`.
 
 Review comment:
   yes.. correct.. the question we need to ask yourselves is "does the user need to do any
action" to migrate.. No action is needed here. That is why I don't think this needs to be
moved out
