The Apache Flume team is pleased to announce the release of Flume 1.4.0.

Flume is a distributed, reliable, and available service for efficiently
collecting, aggregating, and moving large amounts of streaming event data.

Version 1.4.0 is the fourth Flume release as an Apache top-level project.
Flume 1.4.0 is stable, production-ready software, and is backwards-compatible
with previous versions of the Flume 1.x codeline.

Six months of active development went into this release: 261 patches were committed since 1.3.1, representing many features, enhancements, and bug fixes. While the full change log can be found on the 1.4.0 release page (link below), here are a few new feature highlights:

* New JMS Source
* New Solr Sink with ETL capabilities
* Updated ElasticSearch sink to support ES version 0.90
* Support for secure SSL transport over Avro-RPC clients, sources & sinks
* Support for Thrift-RPC as a transport mechanism
* Support for embedding a Flume agent within applications
* Support for a new plugins.d directory structure for managing Flume addons
* Support for reading Avro files via the Spooling Directory source
* Support for writing Avro files with arbitrary schemas via the HDFS sink
* Support for ingesting Avro-serializable objects via the log4j API
* Improvements to the file channel to keep a backup checkpoint to avoid replays
* Performance improvements to the file channel, including group commit
