Apache Solr Release Notes This file lists Solr's raw release notes with details of every change to Solr. Most people will find the solr-upgrade-notes.adoc file more approachable. https://github.com/apache/lucene-solr/blob/master/solr/solr-ref-guide/src/solr-upgrade-notes.adoc ================== 8.6.3 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release. Bug Fixes --------------------- * SOLR-14859: DateRangeField now throws errors when invalid field/fieldType options specified; no longer silently accepts incompatible option values (Jason Gerlowski, Chris Hostetter, Munendra S N) * SOLR-14768: Fix HTTP multipart POST to Solr -- a regression from 8.6.0. Many Jetty classes are not classpath-visible from the Solr webapp. (David Smiley) * SOLR-14850: Fix ExactStatsCache NullPointerException when shards.tolerant=true. (Yevhen Tienkaiev via ab) * SOLR-14897: Fix unlimited number of forwarding the request from one node to another node. (hossman, Munendra S N) * SOLR-14898: Stop returning duplicate HTTP response headers when requests are forward to another node. (hossman) * SOLR-14835: Solr 8.6.x log starts with "XmlConfiguration Ignored arg" warning from Jetty. This incorrect message is caused by a bug in Jetty 9.4.27 and can be safely ignored (the configuration is still correctly processed). (Colving Cowie, ab) ================== 8.6.2 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release. Bug Fixes --------------------- * SOLR-14751: Zookeeper Admin screen not working for old ZK versions (janhoy) * SOLR-14663: Copy ConfigSet root data from base ConfigSet when using CREATE command (Andras Salamon, Tomás Fernández Löbbe) ================== 8.6.1 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release. Bug Fixes --------------------- * SOLR-14665, SOLR-14706: Revert SOLR-12845 adding of default autoscaling cluster policy, due to performance issues. (Ishan Chattopadhyaya, Houston Putman, Gus Heck, ab) * SOLR-14671: Parsing dynamic ZK config sometimes cause NumberFormatException (janhoy) ================== 8.6.0 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release. New Features --------------------- * SOLR-14210: HealthCheckHandler can now require that all cores are healthy before returning 'OK' To enable, add &requireHealthyCores=true to enable (janhoy, Houston Putman, shalin) * SOLR-13942: A read API at /api/cluster/zk/* to fetch raw ZK data and view contents of a ZK directory (noble) * SOLR-14237: A new panel with security info in admin UI's dashboard (Ishan Chattopadhyaya, Moshe Bla) * SOLR-12131: ExternalRoleRuleBasedAuthorizationPlugin which gets user's roles from request (janhoy) * SOLR-14478: Allow the diff Stream Evaluator to operate on the rows of a matrix (Joel Bernstein) * SOLR-14476: Add percentiles and standard deviation aggregations to stats, facet and timeseries Streaming Expressions (Joel Bernstein) * SOLR-14470: Add streaming expressions to /export handler. (ab, Joel Bernstein) * SOLR-14404: CoreContainer level custom requesthandlers (noble) * SOLR-13749: Join queries can now work cross-collection, even when sharded or when spanning nodes. (Dan Fox, Kevin Watters, via Gus Heck, David Smiley) * SOLR-14481: Add drill Streaming Expression for efficient and accurate high cardinality aggregation. (Joel Bernstein) * SOLR-14599: Package manager support for cluster level plugins (see SOLR-14404) (Ishan Chattopadhyaya) * SOLR-14590: Add support for RankFields. RankFields allow the use of per-document scoring factors in a way that lets Solr skip over non-competitive documents when ranking. See SOLR-13289. (Tomás Fernández Löbbe, Varun Thacker) Improvements --------------------- * SOLR-14316: Remove unchecked type conversion warning in JavaBinCodec's readMapEntry's equals() method (Aroop Ganguly, Tomás Fernández Löbbe, Noble Paul, Anshum Gupta) * SOLR-14260: Make SolrJ ConnectionSocketFactory pluggable via SocketFactoryRegistryProvider setting on HttpClientUtil (Andy Throgmorton via David Smiley) * SOLR-14342: Load cores in an order that makes collections available sooner and reduces leaderVoteWait timeouts in large SolrCloud clusters. (David Smiley) * SOLR-14329: Add support to choose collapse group to expand in ExpandComponent based on cost (Munendra S N) * SOLR-14307: User defined "<cache/>" entries in solrconfig.xml now support enabled="true|false" just like core searcher caches. (hossman) * SOLR-14364: LTR's SolrFeature "fq" now supports PostFilters (e.g. collapse). (David Smiley) * SOLR-14396: TaggerRequestHandler should not error on an empty index (Trey Grainger) * SOLR-12845: Add a default autoscaling cluster policy. (shalin, varunthacker, ab) * SOLR-14433: Metrics: SolrShardReporter's default metrics list now includes TLOG and UPDATE./update (David Smiley) * SOLR-14423: Move static SolrClientCache from StreamHandler to CoreContainer for wider reuse and better life-cycle management. (ab) * SOLR-14407: Handle shards.purpose in the postlogs tool (Joel Bernstein) * SOLR-13325: ComputePlanAction now supports a collection selector of the form `collections: {policy: my_policy}` which can be used to select multiple collections that match collection property/value pairs. This is useful to maintain a whitelist of collections for which actions are taken without needing to hard code the collection names themselves. The collection hints are pushed down to the policy engine so operations for non-matching collections are not computed at all. (ab, shalin) * SOLR-14419: json.queries as well as other parameters might be referred via {"param":"ref"} in Query DSL (Mikhail Khludnev) * SOLR-11334: hl.fl and tv.fl now parse field lists when they have both commas and spaces (David Smiley, Yasufumi Mizoguchi) * SOLR-14442: bin/solr and bin\solr.cmd invoke jstack <SOLR_PID> before forceful termination, if jstack is available. Also, bin\solr.cmd executes forceful termination even port is unbinded already (Christine Poerschke via Mikhail Khludnev). * SOLR-14384: SolrRequestInfo now stacks internally when a new request is set/clear'ed. Also fixes SolrIndexSearcher.warm which should have re-instated previous SRI. (Nazerke Seidan, David Smiley) * SOLR-14561: CoreAdminAPI's parameters instanceDir and dataDir are now validated, and must be relative to either SOLR_HOME, SOLR_DATA_HOME or coreRootDir. Added new solr.xml config 'allowPaths', controlled by system property 'solr.allowPaths' that allows you to add other allowed paths when needed. * SOLR-13286: Metrics will no longer write a (sometimes large) log message every minute. This can be re-enabled via log4j2.xml if desired, or other HttpSolrCall log messages may be quieted on a per handler basis. (Gus Heck) * SOLR-14539: Introducing {!bool excludeTags=...} for Query DSL. (Mikhail Khludnev) Optimizations --------------------- * SOLR-8306: Do not collect expand documents when expand.rows=0 (Marshall Sanders, Amelia Henderson) * SOLR-14340: Remove unnecessary configset verification checks when SolrCloud merely wants to know which configset a collection is using. Improves CLUSTERSTATUS times for massive clusters. (Mathieu Marie, David Smiley) * SOLR-14365: CollapsingQParser - Avoiding always allocate int[] and float[] with size equals to number of unique values. (Cao Manh Dat) * SOLR-14376: Optimize filter queries that match all docs. (David Smiley) * LUCENE-7788: fail precommit on unparameterised log messages and examine for wasted work/objects (Erick Erickson) * SOLR-13289: When the "minExactCount" parameters is provided in queries and it's value is lower than the number of hits, Solr can speedup the query resolution by using the Block-Max WAND algorithm (see L
