6 June 2017, Apache Solr 6.6.0 availableSolr 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 and analytics, rich document parsing,
geospatial search, extensive REST APIs as well as parallel SQL. Solr
is enterprise grade, secure and 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
6.6.0 is available for immediate download at: .

https://lucene.apache.org/solr/6_6_0/changes/Changes.htmlSolr 6.6
Release Highlights:Fields and field types:* Payload support with
payload() value source and {!payload_score} and {!payload_check}
query parsers* Solr support for SimpleTextCodec, via <codecFactory
class="solr.SimpleTextCodecFactory"/> in solrconfig.xml (per-field
specification in the schema is not possible)* Multi-field support to
TermsComponent when requesting terms' statistics* Grouping support
with PointFields* CollapseQParser support with PointFields*
ExpandComponent support with PointFieldsNew API:* UPLOAD command
(Config Set API) for uploading zipped configsets* MOVEREPLICA command
(Collections API) for moving a replica across nodes* LISTALIASES
command (Collections API) to return a list of all collection aliases*
STATUS command (Core Admin API) to emit collection details of each
coreScript:* Basic authentication can be enabled/disabled using
bin/solr|bin/solr.cmd* ls command to ZkCLI for listing only
sub-directories* bin/solr script now prints warning when available
system entropy is lower than 300* solr.in.sh installed by install
script should be writable by solr userFaceting:* Variance and Standard
Deviation aggregators for the JSON Facet API* JSON Faceting now
supports a query time 'join' domain change optionStreaming expressions
and evaluators:* CartesianProductStream, which turns a single tuple
with a multi-valued field into N tuples, one for each value in the
multi-valued field* Basic math Streaming Evaluators* UUID Streaming
Evaluator* Date/time Stream Evaluators* analyze Stream Evaluator to
support streaming NLP* shuffle Streaming Expression* search Streaming
Expression should work in non-SolrCloud mode* echo Streaming
Expression* eval Streaming Expression* timeseries Streaming
Expression* let, get and tuple Streaming Expressions* Correlation
Stream Evaluator* stats Streaming Expression should work in
non-SolrCloud mode* regress and predict Stream Evaluators* covariance
Stream Evaluator* convolution Stream Evaluator* normalize Stream
EvaluatorExamples:* Solr default/example uses
WordDelimiterGraphFilterFactory and SynonymGraphFilterFactory* New
DataImportHandler 'atom' example, replacing broken 'rss' example*
Redone DataImportHandler 'tika' example, removing all unused and
irrelevant definitionsMetrics:* Expose cache statistics using metrics
API* Improvements to metric reporters and API: support for "regex"
parameter in /admin/metrics, "enabled" flag in reporter
configurations, correct handling of "serviceUrl" in SolrJmxReporter,
better handling of service clients for JMX, Ganglia and Graphite
reportersUpgrades/deprecations/removals:* Upgraded Metrics library to
3.2.2, Zookeeper to 3.4.10* Deprecated LatLonType, GeoHashField,
SpatialPointVectorFieldType, and SpatialTermQueryPrefixTreeFieldType.
Instead, switch to LatLonPointSpatialField or
SpatialRecursivePrefixTreeFieldType or RptWithGeometrySpatialField*
Deprecated PostingsSolrHighlighter. Use UnifiedSolrHighlighter
instead.* Removed Solr contribs: map-reduce, morphlines-core and
morphlines-cellSolrJ:* CloudSolrClient can now be initialized using
the base URL of a Solr instance instead of ZooKeeper hosts* SolrJ:
Added SolrParams.toLocalParamsString() and
ClientUtils.encodeLocalParamVal* LBHttpSolrClient.doRequest is now
always wrapped in a Mapped Diagnostic Context (MDC)Others:* New
AtomicUpdateProcessor to convert normal update operations to atomic
update operations* totalTermFreq support to TermsComponent* Hide
keystore and truststore passwords from /admin/info/* outputs*
Configurability for thread pool size to recoveryExecutor* Introducing
sort=childfield(field) asc for searching by {!parent}* Transient core
cache is now pluggable* Renamed getSortWithinGroup to
getWithinGroupSort in search.grouping.CommandOptimizations:*
facet.heatmap is now significantly faster when the docset (base query)
matches everything and there are no deleted docs. It is also faster
when the docset matches a small fraction of the index or none* Reduced
heap consumption for filter({!join ... score=...}) * JSON Facet API
now uses hyper-log-log++ for determining the number of buckets when
merging requests from a multi-shard distributed request* Better
ZkStateWriter batching* Using cache for DistributedQueue in case of
single-consumerFurther details of changes are available in the change
