+
+
+<!--more-->
+
+**IMPORTANT NOTE**: We may introduce a **backward incompatible changes regarding samza job submission** in the future 1.4 release. Details can be found on [SEP-23: Simplify Job Runner](https://cwiki.apache.org/confluence/display/SAMZA/SEP-23%3A+Simplify+Job+Runner)
+
+We’re thrilled to announce the release of Apache Samza 1.3.0.
+
+Today Samza forms the backbone of hundreds of real-time production applications across a multitude of companies, such as LinkedIn, VMWare, Slack, Redfin among many others. Samza provides leading support for large-scale stateful stream processing with:
+
+* First class support for local state (with RocksDB store). This allows a stateful application to scale up to 1.1 Million events/sec on a single machine with SSD.
+
+* Support for incremental checkpointing of state instead of full snapshots. This enables Samza to scale to applications with very large state.
+
+* A fully asynchronous programming model that makes parallelizing remote calls efficient and effortless.
+
+* High level API for expressing complex stream processing pipelines in a few lines of code.
+
+* Beam Samza Runner that marries Beam’s best in class support for EventTime based windowed processing and sophisticated triggering with Samza’s stable and scalable stateful processing model.
+
+* A fully pluggable model for input sources (e.g. Kafka, Kinesis, DynamoDB streams etc.) and output systems (HDFS, Kafka, ElastiCache etc.).
+
+* A Table API that provides a common abstraction for accessing remote or local databases and allowing developers are able to "join" an input event stream with such a Table.
+
+* Flexible deployment model for running the applications in any hosting environment and with cluster managers other than YARN.
+
+* Features like canaries, upgrades and rollbacks that support extremely large deployments with minimal downtime.
+
+###  **New Features, Upgrades and Bug Fixes:**
+This release brings the following features, upgrades, and capabilities (highlights):
