+<p><strong>IMPORTANT NOTE</strong>: We may introduce <strong>backward incompatible changes regarding samza job submission</strong> in the future 1.5 release. Details can be found on <a href="https://cwiki.apache.org/confluence/display/SAMZA/SEP-23%3A+Simplify+Job+Runner">SEP-23: Simplify Job Runner</a></p>
+
+<p>We are thrilled to announce the release of Apache Samza 1.4.0.</p>
+
+<p>Today, Samza forms the backbone of hundreds of real-time production applications across a multitude of companies, such as LinkedIn, Slack, and Redfin, among many others. Samza provides leading support for large-scale stateful stream processing with:</p>
+
+<ul>
+<li><p>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.</p></li>
+<li><p>Support for incremental checkpointing of state instead of full snapshots. This enables Samza to scale to applications with very large state.</p></li>
+<li><p>A fully asynchronous programming model that makes parallelizing remote calls efficient and effortless.</p></li>
+<li><p>High level API for expressing complex stream processing pipelines in a few lines of code.</p></li>
+<li><p>Beam Samza Runner that marries Beamâs best in class support for EventTime based windowed processing and sophisticated triggering with Samzaâs stable and scalable stateful processing model.</p></li>
+<li><p>A fully pluggable model for input sources (e.g. Kafka, Kinesis, DynamoDB streams etc.) and output systems (HDFS, Kafka, ElastiCache etc.).</p></li>
+<li><p>A Table API that provides a common abstraction for accessing remote or local databases and allowing developers are able to âjoinâ an input event stream with such a Table.</p></li>
+<li><p>Flexible deployment model for running the applications in any hosting environment and with cluster managers other than YARN.</p></li>
+</ul>
+
+<h3 id="new-features-upgrades-and-bug-fixes">New Features, Upgrades and Bug Fixes:</h3>
+
+<p>This release brings the following features, upgrades, and capabilities (highlights):</p>
+
+<ul>
+<li><p>Improvements regarding management and monitoring of local state</p></li>

Instead of retaining all messages, you typically define a more compact data structure for the WindowPane and update it incrementally as new messages arrive, e.g. for keeping a count of messages in the window.

This is particularly useful when the window is configured with early or late triggers. The accumulation mode can either be discarding or accumulating.</p>
