[Sebastian Nagel <wa...@googlemail.com.INVALID>]

The Apache Nutch [0] Project Management Committee are pleased to announce
the immediate release of Apache Nutch v1.15. We advise all current users
and developers of the 1.X series to upgrade to this release.

Nutch is a well matured, production ready Web crawler. Nutch 1.x enables
fine grained configuration, relying on Apache Hadoop™ [1] data structures,
which are great for batch processing.

As usual in the 1.X series, release artifacts are made available as both
source and binary and also available within Maven Central [2] as a Maven
dependency. The release is available from our downloads page [3].

This release includes more than 100 bug fixes and improvements, the full
list of changes can be seen in the release report [4], the most notable
ones are:


 NUTCH-1480 Multiple index writer instances with different configurations
  It's now possible to index documents into multiple Solr or Elasticsearch
  instances.

  Please note that this feature changed the way indexers are configured,
  see https://wiki.apache.org/nutch/IndexWriters for more information.

 NUTCH-2412 Exchange component for indexing job
