11 February 2019, Apache Solr™ 7.7.0 available

The Lucene PMC is pleased to announce the release of Apache Solr 7.7.0

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 (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 7.7.0 is available for immediate download at: http://lucene.apache.org/solr/downloads.html

See http://lucene.apache.org/solr/7_7_0/changes/Changes.html for a full list of details.

Solr 7.7.0 Release Highlights:

Bug Fixes

  • URI Too Long with large streaming expressions in SolrJ.
  • A failure while reloading a SolrCore can result in the SolrCore not being closed.
  • Spellcheck parameters not working in new UI.
  • New Admin UI Query does not URL-encode the query produced in the URL box.
  • Rule-base Authorization plugin skips authorization if querying node does not have collection replica.
  • Solr installer fails on SuSE linux.
  • Fix incorrect SOLR_SSL_KEYSTORE_TYPE variable in solr start script.

Improvements

  • Add a login page to Admin UI, with initial support for Basic Auth and Kerberos.
  • New Node-level health check handler at /admin/info/healthcheck and /node/health paths that checks if the node is live, connected to zookeeper and not shutdown.
