Latest stable release (v1.5.0)

Apache Flink® 1.5.0 is our latest stable release.

An Apache Hadoop installation is not required to use Flink. If you plan to run Flink in YARN or process data stored in HDFS then select the version matching your installed Hadoop version.

The binary releases marked with a Hadoop version come bundled with binaries for that Hadoop version, the binary release without bundled Hadoop can be used without Hadoop or with a Hadoop version that is installed in the environment, i.e. this version can pick up a Hadoop version from the classpath.

Release Notes

Please have a look at the Release Notes for Flink 1.5 if you plan to upgrade your Flink setup from a previous version.

Verifying Hashes and Signatures

Along our releases, we also provide sha512 hashes in *.sha512 files and cryptographic signatures in *.asc files. The Apache Software Foundation has an extensive tutorial to verify hashes and signatures which you can follow by using any of these release-signing KEYS.

Maven Dependencies

You can add the following dependencies to your pom.xml to include Apache Flink in your project. These dependencies include a local execution environment and thus support local testing.

  • Scala API: To use the Scala API, replace the flink-java artifact id with flink-scala_2.11 and flink-streaming-java_2.11 with flink-streaming-scala_2.11.

Update Policy for old releases

As of March 2017, the Flink community decided to support the current and previous minor release with bugfixes. If 1.2.x is the current release, 1.1.y is the previous minor supported release. Both versions will receive bugfixes for critical issues.

Note that the community is always open for discussing bugfix releases for even older versions. Please get in touch with the developers for that on the dev@flink.apache.org mailing list.

All releases

All Flink releases are available via https://archive.apache.org/dist/flink/ including checksums and cryptographic signatures. At the time of writing, this includes the following versions:
