Re: [ANNOUNCE] Apache Solr 7.0.0 released

It’s strange but something seems to have stripped off all the formatting from 
the announce mail. Here’s a plain text version of the same and hope this is 
more readable.


20 September 2017, Apache Solr™ 7.0.0 available

Solr is the popular, blazing fast, open source NoSQL search platform from the 
Apache Lucene project. Its major features include powerful full-text search, 
hit highlighting, faceted search, dynamic clustering, database integration, 
rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly 
scalable, providing fault tolerant distributed search and indexing, and powers 
the search and navigation features of many of the world's largest internet 
sites. 

Solr 7.0.0 is available for immediate download at: 
http://lucene.apache.org/solr/mirrors-solr-latest-redir.html 


See http://lucene.apache.org/solr/7_0_0/changes/Changes.html 
 for a full list of 
details. 

  * Replica Types - Solr 7 supports different replica types, which handle 
updates differently. In addition to pure NRT operation where all replicas build 
an index and keep a replication log, you can now also add so called PULL 
replicas, achieving the read-speed optimized benefits of a master/slave setup 
while at the same time keeping index redundancy. 

  * Auto-scaling. Solr can now allocate new replicas to nodes using a new auto 
scaling policy framework. This framework will in future releases enable Solr to 
move shards around based on load, disk etc. 

  * Indented JSON is now the default response format for all APIs, pass wt=xml 
and/or indent=off to use the previous unindented XML format. 

  * The JSON Facet API now supports two-phase facet refinement to ensure 
accurate counts and statistics for facet buckets returned in distributed mode. 

  * Streaming Expressions adds a new statistical programming syntax for the 
statistical analysis of sql queries, random samples, time series and graph 
result sets. 

  * Analytics Component version 2.0, which now supports distributed 
collections, expressions over multivalued fields, a new JSON request language, 
and more. 

  * The new v2 API, exposed at /api/ and also supported via SolrJ, is now the 
preferred API, but /solr/ continues to work. 

  * A new '_default' configset is used if no config is specified at collection 
creation. The data-driven functionality of this configset indexes strings as 
analyzed text while at the same time copying to a '*_str' field suitable for 
faceting. 

  * Solr 7 is tested with and verified to support Java 9. 

Being a major release, Solr 7 removes many deprecated APIs, changes various 
parameter defaults and behavior. Some changes may require a re-index of your 
content. You are thus encouraged to thoroughly read the "Upgrade Notes" at 
http://lucene.apache.org/solr/7_0_0/changes/Changes.html 
 or in the 
CHANGES.txt file accompanying the release. 

Solr 7.0.0 also includes many other new features as well as numerous 
optimizations and bugfixes of the corresponding Apache Lucene release. 

Please report any feedback to the mailing lists 
(http://lucene.apache.org/solr/discussion.html 
) 

Note: The Apache Software Foundation uses an extensive mirroring network for 
distributing releases. It is possible that the mirror you are using may not 
have replicated the release yet. If that is the case, please try another 
mirror. This also goes for Maven access.
