Fields:
 * PointFields (fixed-width multi-dimensional numeric & binary types enabling fast range search) are now supported
 * In-place updates to numeric docValues fields (single valued, non-stored, non-indexed) supported using atomic update syntax
 * A new LatLonPointSpatialField that uses points or doc values for query
 * It is now possible to declare a field as "large" in order to bypass the document cache

Queries:
 * New sow=false request param (split-on-whitespace) for edismax & standard query parsers enables query-time multi-term synonyms
 * XML QueryParser (defType=xmlparser) now supports span queries

Query / Fields:
 * PointFields are now supported
 * PointFields also uses IndexOrDocValuesQuery when possible
 * In-place updates to numeric docValues fields (single valued, non-stored, non-indexed) supported using atomic update syntax
 * A new LatLonPointSpatialField that uses points or doc values for query
 * It is now possible to declare a field as "large" in order to bypass the document cache
 * Document builder now reorders largest field values as last
 * Support span queries in SolrCoreParser now supports span queries
 * A memory efficient DocSet if a query returns all docs
 * Solr's edismax and "Lucene"/standard query parsers can optionally not split on whitespace before sending terms to analysis

Metrics / Logging:
 * Metrics API now supports non-numeric metrics (version, disk type, component state, system properties...)
 * The disk free and aggregated disk free metrics are now reported
 * Pre-start rotation logging is reduced
 * The DirectUpdateHandler2 now implements MetricsProducer and exposes stats via the metrics api and configured reporters.

UI:
 * It is now possible to delete a shard in the admin UI.
Ease of use / Admin UI:
 * Added modernized self-documenting /v2 API

SolrCloud:
 * Arbitrary java system properties can be passed to zkcli
 * solr.cloud.wait-for-updates-with-stale-state-pause default is lowered from 7s to 2s in order to reduce the amount of replicas out-of-sync.
 * UpdateRequestProcessors now have a way to guarantee the closing of resources used for a request
 * .system collection is now created on first request if it does not exist
Optimizations:
 * BlockCache is faster due to less failures when caching a new block
 * MMapDirectoryFactory now supports "preload" option to ask mapped pages to be loaded into physical memory on init

Please note, this release cannot be built from source with
Java 8 update 121, use an earlier version instead! This is
caused by a bug introduced into the Javadocs tool shipped
with that update. The workaround was too late for this
Solr release. Of course, you can use the binary
artifacts.

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 applies to Maven access.
