## 26 July 2019, Apache Solr™ 8.2.0 available


The Lucene PMC is pleased to announce the release of Apache Solr 8.2.0.


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 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 8.2.0 is available for immediate download at:


  <https://lucene.apache.org/solr/downloads.html>


### Solr 8.2.0 Release Highlights:


#### New features


  * Add an update param failOnVersionConflicts=false to updates not fail
when there is a version conflict

  * Add facet2D Streaming Expression.

  * Preferred replicas on nodes with same system properties as the query
master

  * OpenTracing support for Solr

  * Raw index data analysis tool (extension of COLSTATUS collection
command).

  * Add recNum Stream Evaluator.

  * Allow zplot to visualize 2D clusters and convex hulls.

  * Add a field type for Estonian language to default managed_schema,
document about Estonian language analysis in Solr Ref Guide


#### Bug Fixes


  * Intermittent 401's for internode requests with basicauth enabled.

  * In 8.1, Atomic Updates were broken (NPE) when the schema declared the
new _nest_path_ field even if you weren't using nested docs. In-place
updates were not affected (worked)

  * Fix atomic update encoding issue for UUID, enum, bool, and binary
fields.

  * Impossible to delete a collection with the same name as an existing
alias. This fixes also a bug inREINDEXCOLLECTION when used with
removeSource=true which could lead to a data loss.
