+## [Release 0.5.3](https://github.com/apache/hudi/releases/tag/release-0.5.3)
([docs](/docs/0.5.3-quick-start-guide.html))
+
+### Download Information
+ * Source Release : [Apache Hudi 0.5.3 Source
Release](https://downloads.apache.org/hudi/0.5.3/hudi-0.5.3.src.tgz)
([asc](https://downloads.apache.org/hudi/0.5.3/hudi-0.5.3.src.tgz.asc),
[sha512](https://downloads.apache.org/hudi/0.5.3/hudi-0.5.3.src.tgz.sha512))
+ * Apache Hudi jars corresponding to this release is available
[here](https://repository.apache.org/#nexus-search;quick~hudi)
+
+### Migration Guide for this release
+ * This is a bug fix only release and no special migration steps needed when
upgrading from 0.5.2. If you are upgrading from earlier releases “X”, please
make sure you read the migration guide for each subsequent release between “X”
and 0.5.3
+ * 0.5.3 is the first hudi release after graduation. As a result, all hudi
jars will no longer have "-incubating" in the version name. In all the places
where hudi version is referred, please make sure "-incubating" is no longer
present.
+
+For example hudi-spark-bundle pom dependency would look like:
+```xml
+ <dependency>
+ <groupId>org.apache.hudi</groupId>
+ <artifactId>hudi-spark-bundle_2.12</artifactId>
+ <version>0.5.3</version>
+ </dependency>
+```
+### Release Highlights
+ * Hudi now supports `aliyun OSS` storage service.
+ * Embedded Timeline Server is enabled by default for both delta-streamer and
spark datasource writes. This feature was in experimental mode before this
release. Embedded Timeline Server caches file listing calls in Spark driver and
serves them to Spark writer tasks. This reduces the number of file listings
needed to be performed for each write.
+ * Incremental Cleaning is enabled by default for both delta-streamer and
spark datasource writes. This feature was also in experimental mode before this
release. In the steady state, incremental cleaning avoids the costly step of
scanning all partitions and instead uses Hudi metadata to find files to be
cleaned up.
+ * Delta-streamer config files can now be placed in different filesystem than
actual data.
+ * Hudi Hive Sync now supports tables partitioned by date type column.
+ * Hudi Hive Sync now supports syncing directly via Hive MetaStore. You simply
need to set hoodie.datasource.hive_sync.use_jdbc
+=false. Hive Metastore Uri will be read implicitly from environment. For
example, when writing through Spark Data Source,
+```xml
+ spark.write.format(“hudi”)
+ .option(…)
+ .option(“hoodie.datasource.hive_sync.username”, “<user>”)
+ .option(“hoodie.datasource.hive_sync.password”, “<password>”)
+ .option(“hoodie.datasource.hive_sync.partition_fields”, “<partition_fields>”)
+ .option(“hoodie.datasource.hive_sync.database”, “<db_name>”)
+ .option(“hoodie.datasource.hive_sync.table”, “<table_name>”)
+ .option(“hoodie.datasource.hive_sync.use_jdbc”, “false”)
+ .mode(APPEND)
+ .save(“/path/to/dataset”)
+```
+
+ * Other Writer Performance related fixes:
+ - DataSource Writer now avoids unnecessary loading of data after write.
+ - Hudi Writer now leverages spark parallelism when searching for existing
files for writing new records.
