+We are pleased to announce the availability of Flink 0.7.0. This release includes new user-facing features as well as performance and bug fixes, brings the Scala and Java APIs in sync, and introduces Flink Streaming. A total of 34 people have contributed to this release, a big thanks to all of them!

+
+##Overview of major new features
+
+**Flink Streaming:** The gem of the 0.7.0 release is undoubtedly Flink Streaming. Available currently in alpha, Flink Streaming provides a Java API on top of Apache Flink that can consume streaming data sources (e.g., from Apache Kafka, Apache Flume, and others) and process them in real time. A dedicated blog post on Flink Streaming and its performance is coming up here soon. You can check out the Streaming programming guide [here](http://flink.incubator.apache.org/docs/0.7-incubating/streaming_guide.html).
+
+**New Scala API:** The Scala API has been completely rewritten. The Java and Scala APIs have now the same syntax and transformations and will be kept from now on in sync in every future release. See the new Scala API [here](http://flink.incubator.apache.org/docs/0.7-incubating/programming_guide.html).
+
+**Logical key expressions:** You can now specify grouping and joing keys with logical names for member variables of POJO data types. For example, you can join two data sets as ``persons.join(cities).where(âzipâ).equalTo(âzipcodeâ)``. Read more [here](http://flink.incubator.apache.org/docs/0.7-incubating/programming_guide.html#specifying-keys).
+
+**Hadoop MapReduce compatibility:** You can run unmodified Hadoop Mappers and Reducers (mapred API) in Flink, use all Hadoop data types, and read data with all Hadoop InputFormats.
+
+**Collection-based execution backend:** The collection-based execution backend enables you to execute a Flink job as a simple Java collections program, bypassing completely the Flink runtime and optimizer. This feature is extremely useful for prototyping, and embedding Flink jobs in projects in a very lightweight manner.
+
+**Record API deprecated:** The (old) Stratosphere Record API has been marked as deprecated and is planned for removal in the 0.9.0 release.
+
+**BLOB service:** This release contains a new service to distribute jar files and other binary data among the JobManager, TaskManagers and the client.
+
+**Intermediate data sets:** A major rewrite of the system internals introduces intermediate data sets as first class citizens. The internal state machine that tracks the distributed tasks has also been completely rewritten for scalability. While this is not visible as a user-facing feature yet, it is the foundation for several upcoming exciting features.
+
+**Note:** Currently, there is limited support for Java 8 lambdas when compiling and running from an IDE. The problem is due to type erasure and whether Java compilers retain type information. We are currently working with the Eclipse and OpenJDK communities to resolve this.

- <p class="meta">13 Jan 2014</p>
-
- <div><p>We are pleased to announce that version 0.4 of the Stratosphere system has been released. </p>
-
-<p>Our team has been working hard during the last few months to create an improved and stable Stratosphere version. The new version comes with many new features, usability and performance improvements in all levels, including a new Scala API for the concise specification of programs, a Pregel-like API, support for Yarn clusters, and major performance improvements. The system features now first-class support for iterative programs and thus covers traditional analytical use cases as well as data mining and graph processing use cases with great performance.</p>
-
-<p>In the course of the transition from v0.2 to v0.4 of the system, we have changed pre-existing APIs based on valuable user feedback. This means that, in the interest of easier programming, we have broken backwards compatibility and existing jobs must be adapted, as described in <a href="/blog/tutorial/2014/01/12/0.4-migration-guide.html">the migration guide</a>.</p>
-
-<p>This article will guide you through the feature list of the new release.</p>
-
-<h3 id="scala-programming-interface">Scala Programming Interface</h3>
-
-<p>The new Stratosphere version comes with a new programming API in Scala that supports very fluent and efficient programs that can be expressed with very few lines of code. The API uses Scala's native type system (no special boxed data types) and supports grouping and joining on types beyond key/value pairs. We use code analysis and code generation to transform Scala's data model to the Stratosphere runtime. Stratosphere Scala programs are optimized before execution by Stratosphere's optimizer just like Stratosphere Java programs.</p>
-
-<p>Learn more about the Scala API at the <a href="/docs/0.4/programming_guides/scala.html">Scala Programming Guide</a></p>
-
-<h3 id="iterations">Iterations</h3>
-
-<p>Stratosphere v0.4 introduces deep support for iterative algorithms, required by a large class of advanced analysis algorithms. In contrast to most other systems, "looping over the data" is done inside the system's runtime, rather than in the client. Individual iterations (supersteps) can be as fast as sub-second times. Loop-invariant data is automatically cached in memory.</p>
-
-<p>We support a special form of iterations called âdelta iterationsâ that selectively modify only some elements of intermediate solution in each iteration. These are applicable to a variety of applications, e.g., use cases of Apache Giraph. We have observed speedups of 70x when using delta iterations instead of regular iterations.</p>
-
-<p>Read more about the new iteration feature in <a href="/docs/0.4/programming_guides/iterations.html">the documentation</a></p>
-
-<h3 id="hadoop-yarn-support">Hadoop YARN Support</h3>
-
-<p>YARN (Yet Another Resource Negotiator) is the major new feature of the recently announced <a href="http://hadoop.apache.org/docs/r2.2.0/">Hadoop 2.2</a>. It allows to share existing clusters with different runtimes. So you can run MapReduce alongside Storm and others. With the 0.4 release, Stratosphere supports YARN.
-Follow <a href="/docs/0.4/setup/yarn.html">our guide</a> on how to start a Stratosphere YARN session.</p>
-
-<h3 id="improved-scripting-language-meteor">Improved Scripting Language Meteor</h3>
-
-<p>The high-level language Meteor now natively serializes JSON trees for greater performance and offers additional operators and file formats. We greatly empowered the user to write crispier scripts by adding second-order functions, multi-output operators, and other syntactical sugar. For developers of Meteor packages, the API is much more comprehensive and allows to define custom data types that can be easily embedded in JSON trees through ad-hoc byte code generation.</p>
-
-<h3 id="spargel:-pregel-inspired-graph-processing">Spargel: Pregel Inspired Graph Processing</h3>
-
-<p>Spargel is a vertex-centric API similar to the interface proposed in Google's Pregel paper and implemented in Apache Giraph. Spargel is implemented in 500 lines of code (including comments) on top of Stratosphere's delta iterations feature. This confirms the flexibility of Stratosphere's architecture. </p>
-
-<h3 id="web-frontend">Web Frontend</h3>
-
-<p>Using the new web frontend, you can monitor the progress of Stratosphere jobs. For finished jobs, the frontend shows a breakdown of the execution times for each operator. The webclient also visualizes the execution strategies chosen by the optimizer.</p>
-
-<h3 id="accumulators">Accumulators</h3>
-
-<p>Stratosphere's accumulators allow program developers to compute simple statistics, such as counts, sums, min/max values, or histograms, as a side effect of the processing functions. An example application would be to count the total number of records/tuples processed by a function. Stratosphere will not launch additional tasks (reducers), but will compute the number "on the fly" as a side-product of the functions application to the data. The concept is similar to Hadoop's counters, but supports more types of aggregation.</p>
-
-<h3 id="refactored-apis">Refactored APIs</h3>
-
-<p>Based on valuable user feedback, we refactored the Java programming interface to make it more intuitive and easier to use. The basic concepts are still the same, however the naming of most interfaces changed and the structure of the code was adapted. When updating to the 0.4 release you will need to adapt your jobs and dependencies. A previous blog post has a guide to the necessary changes to adapt programs to Stratosphere 0.4.</p>
-
-<h3 id="local-debugging">Local Debugging</h3>
-
-<p>You can now test and debug Stratosphere jobs locally. The <a href="/docs/0.4/program_execution/local_executor.html">LocalExecutor</a> allows to execute Stratosphere Jobs from IDE's. The same code that runs on clusters also runs in a single JVM multi-threaded. The mode supports full debugging capabilities known from regular applications (placing breakpoints and stepping through the program's functions). An advanced mode supports simulating fully distributed operation locally.</p>
-
-<h3 id="miscellaneous">Miscellaneous</h3>
-
-<ul>
-<li>The configuration of Stratosphere has been changed to YAML</li>
-<li>HBase support</li>
-<li>JDBC Input format</li>
-<li>Improved Windows Compatibility: Batch-files to start Stratosphere on Windows and all unit tests passing on Windows.</li>
-<li>Stratosphere is available in Maven Central and Sonatype Snapshot Repository</li>
-<li>Improved build system that supports different Hadoop versions using Maven profiles</li>
-<li>Maven Archetypes for Stratosphere Jobs.</li>
-<li>Stability and Usability improvements with many bug fixes.</li>
-</ul>
-
-<h3 id="download-and-get-started-with-stratosphere-v0.4">Download and get started with Stratosphere v0.4</h3>

Spargel is implemented in 500 lines of code (including comments) on top of Stratosphere's delta iterations feature. This confirms the flexibility of Stratosphere's architecture. </p>
+
+<h3 id="web-frontend">Web Frontend</h3>
+
+<p>Using the new web frontend, you can monitor the progress of Stratosphere jobs. For finished jobs, the frontend shows a breakdown of the execution times for each operator. The webclient also visualizes the execution strategies chosen by the optimizer.</p>
+
+<h3 id="accumulators">Accumulators</h3>
+
+<p>Stratosphere's accumulators allow program developers to compute simple statistics, such as counts, sums, min/max values, or histograms, as a side effect of the processing functions. An example application would be to count the total number of records/tuples processed by a function. Stratosphere will not launch additional tasks (reducers), but will compute the number "on the fly" as a side-product of the functions application to the data. The concept is similar to Hadoop's counters, but supports more types of aggregation.</p>
+
+<h3 id="refactored-apis">Refactored APIs</h3>
+
+<p>Based on valuable user feedback, we refactored the Java programming interface to make it more intuitive and easier to use. The basic concepts are still the same, however the naming of most interfaces changed and the structure of the code was adapted. When updating to the 0.4 release you will need to adapt your jobs and dependencies. A previous blog post has a guide to the necessary changes to adapt programs to Stratosphere 0.4.</p>
+
+<h3 id="local-debugging">Local Debugging</h3>
+
+<p>You can now test and debug Stratosphere jobs locally. The <a href="/docs/0.4/program_execution/local_executor.html">LocalExecutor</a> allows to execute Stratosphere Jobs from IDE's. The same code that runs on clusters also runs in a single JVM multi-threaded. The mode supports full debugging capabilities known from regular applications (placing breakpoints and stepping through the program's functions). An advanced mode supports simulating fully distributed operation locally.</p>
+
+<h3 id="miscellaneous">Miscellaneous</h3>
+
+<ul>
+<li>The configuration of Stratosphere has been changed to YAML</li>
+<li>HBase support</li>
+<li>JDBC Input format</li>
+<li>Improved Windows Compatibility: Batch-files to start Stratosphere on Windows and all unit tests passing on Windows.</li>
+<li>Stratosphere is available in Maven Central and Sonatype Snapshot Repository</li>
+<li>Improved build system that supports different Hadoop versions using Maven profiles</li>
+<li>Maven Archetypes for Stratosphere Jobs.</li>
+<li>Stability and Usability improvements with many bug fixes.</li>
+</ul>
+
+<h3 id="download-and-get-started-with-stratosphere-v0.4">Download and get started with Stratosphere v0.4</h3>
+
+<p>There are several options for getting started with Stratosphere. </p>

+ <h2>Apache Flink 0.7.0 available</h2>
+ <p class="meta">04 Nov 2014</p>
+
+ <div>
+ <p>We are pleased to announce the availability of Flink 0.7.0. This release includes new user-facing features as well as performance and bug fixes, brings the Scala and Java APIs in sync, and introduces Flink Streaming. A total of 34 people have contributed to this release, a big thanks to all of them!</p>
+
+<p>Download Flink 0.7.0 <a href="http://flink.incubator.apache.org/downloads.html">here</a></p>
+
+<p>See the release changelog <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&version=12327648">here</a></p>
+
+<h2 id="overview-of-major-new-features">Overview of major new features</h2>
+
+<p><strong>Flink Streaming:</strong> The gem of the 0.7.0 release is undoubtedly Flink Streaming. Available currently in alpha, Flink Streaming provides a Java API on top of Apache Flink that can consume streaming data sources (e.g., from Apache Kafka, Apache Flume, and others) and process them in real time. A dedicated blog post on Flink Streaming and its performance is coming up here soon. You can check out the Streaming programming guide <a href="http://flink.incubator.apache.org/docs/0.7-incubating/streaming_guide.html">here</a>.</p>
+
+<p><strong>New Scala API:</strong> The Scala API has been completely rewritten. The Java and Scala APIs have now the same syntax and transformations and will be kept from now on in sync in every future release. See the new Scala API <a href="http://flink.incubator.apache.org/docs/0.7-incubating/programming_guide.html">here</a>.</p>
+
+<p><strong>Logical key expressions:</strong> You can now specify grouping and joing keys with logical names for member variables of POJO data types. For example, you can join two data sets as <code>persons.join(cities).where(âzipâ).equalTo(âzipcodeâ)</code>. Read more <a href="http://flink.incubator.apache.org/docs/0.7-incubating/programming_guide.html#specifying-keys">here</a>.</p>
+
+<p><strong>Hadoop MapReduce compatibility:</strong> You can run unmodified Hadoop Mappers and Reducers (mapred API) in Flink, use all Hadoop data types, and read data with all Hadoop InputFormats.</p>
+
+<p><strong>Collection-based execution backend:</strong> The collection-based execution backend enables you to execute a Flink job as a simple Java collections program, bypassing completely the Flink runtime and optimizer. This feature is extremely useful for prototyping, and embedding Flink jobs in projects in a very lightweight manner.</p>
+
+<p><strong>Record API deprecated:</strong> The (old) Stratosphere Record API has been marked as deprecated and is planned for removal in the 0.9.0 release.</p>
+
+<p><strong>BLOB service:</strong> This release contains a new service to distribute jar files and other binary data among the JobManager, TaskManagers and the client. </p>
+
+<p><strong>Intermediate data sets:</strong> A major rewrite of the system internals introduces intermediate data sets as first class citizens. The internal state machine that tracks the distributed tasks has also been completely rewritten for scalability. While this is not visible as a user-facing feature yet, it is the foundation for several upcoming exciting features.</p>
+
+<p><strong>Note:</strong> Currently, there is limited support for Java 8 lambdas when compiling and running from an IDE. The problem is due to type erasure and whether Java compilers retain type information. We are currently working with the Eclipse and OpenJDK communities to resolve this.</p>
