7 October 2020, Apache Solr™ 8.6.3 available

The Lucene PMC is pleased to announce the release of Apache Solr 8.6.3

...

Primary Solr 8.6.3 Bug Fixes:

• SOLR-14898: Prevent duplicate header accumulation on internally forwarded requestsDuplicate headers no longer accumulate on requests forwarded internally
• SOLR-14768: Fix HTTP multipart POST requests to Solr (8.6.0 regression)
• SOLR-14859: DateRangeField and other PrefixTree-based fields no now reject invalid schema properties instead of quietly returning 0 results on certain queries.
• SOLR-14663: CREATE ConfigSet action now copies base node content

In addition to these bug fixes, 8.6.3 users may notice that their Solr logs start with an "XmlConfiguration Ignored arg" warning produced by Jetty.  This message is caused by an underlying Jetty issue but can be safely ignored as Jetty configuration is still correctly processed.

Further details of changes are available in the change log available at:https://lucene.apache.org/solr/8_6_3/changes/Changes.html

Solr 8.6.3 also includes bugfixes in the corresponding Apache Lucene release:
