Here are the draft release notes. I tried to keep them concise, but please tell me if I miss something important.
Solr 8.6.0 Release Highlights: - Health Check: HealthCheckHandler can now require that all cores are healthy before returning OK. - Zookeeper read API: A read API at /api/cluster/zk/* to fetch raw ZK data and view contents of a ZK directory. - Admin UI: New panel with security info in admin UI's dashboard. - Streaming Expression: Percentiles and standard deviation aggregations added to stats, facet and time series. Streaming expressions added to /export handler. Drill Streaming Expression for efficient and accurate high cardinality aggregation. - Cross-Collection Join Queries: Join queries can now work cross-collection, even when shared or when spanning nodes. Lucene 8.6.0 Release Highlights: - API change in: SimpleFSDireectory, IndexWriterConfig, MergeScheduler, SortFields, SimpleBindings, QueryVisitor, DocValues, CodecUtil. - New: IndexWriter merge-on-commit feature to selectively merge small segments on commit, subject to a configurable timeout, to improve search performance by reducing the number of small segments for searching. Grouping by range based on DoubleValueSource and LongValueSource. - Optimizations: BKD trees and index, DoubleValuesSource/QueryValueSource, UsageTrackingQueryingCachingPolicy, FST, Geometry queries, Points, UniformSplit - Others: Ukrainian analyzer, checksums verification, resource leaks fixes Le mar. 30 juin 2020 à 19:38, Bruno Roustant <bruno.roust...@gmail.com> a écrit : > Erick: > AFAIK yes from now on a commit in branch_8x will not go to 8.6 branch. > > Le mar. 30 juin 2020 à 17:59, Erick Erickson <erickerick...@gmail.com> a > écrit : > >> Bruno: >> >> Just to double check, anything committed to branch_8x from here on won’t >> affect the 8.6 release unless explicitly backported, correct? >> >> I may be close to upgrading Zookeeper to 3.6.1, and very much do NOT want >> it in the 8.6 release as it should bake longer than 2 weeks even… >> >> Thanks for managing this release! >> >> Erick >> >> > On Jun 30, 2020, at 11:34 AM, Bruno Roustant <bruno.roust...@gmail.com> >> wrote: >> > >> > For the RC, I prefer to let the latest and greatest commits to bake a >> week rather than only 2 days.
