Re: [ANNOUNCE] Apache Solr 8.3.0 released

Cassandra Targett
We’re still working out the changes to the publication process, and got a couple wires crossed that prevented the Ref Guide from being published at the same time for this release.

I’ve published the final version now:

Apologies for the confusion, by the next release we expect to have all this worked out.

Hey Ishan,

Somedays back it was announced that the foundation will majorly focus on
HTML guides now and thus, 8.2 guide was released (which was said to be
shorter than 8.0). C*an we expect Ref Guide 8.3 in coming days* or maybe is
it not required? Asking because we are planning to upgrade to latest stable
Solr versions and to keep us updated all times, we will be referring the
latest guides and incorporated changes in each release.

## 2 November 2019, Apache Solr™ 8.3.0 available

The Lucene PMC is pleased to announce the release of Apache Solr 8.3.0.

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 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 8.3.0 is available for immediate download at:


### Solr 8.3.0 Release Highlights:

*Two dimensional routed aliases are now available for organizing
collections based on the data values of two fields
*SPLITSHARD implements a new splitByPrefix option that takes into
account the actual document distribution when using compositeIds
*QueryElevationComponent can have query rules configured with
match="subset" wherein the words need only match a subset of the
query's words and in any order
*Command line option to export documents to a file
*Support deterministic replica routing preferences for better cache usage
*Ability to query aliases in Solr Admin UI
*JWTAuthPlugin supports multiple JWKS endpoints and multiple IdP issuers

*Add upper, lower, trim and split Stream Evaluators
*Add CsvStream, TsvStream Streaming Expressions and supporting
Stream Evaluators
*Add CaffeineCache, an efficient implementation of SolrCache
*Live SPLITSHARD can lose updates due to cluster state change
between checking if the current shard is active and later checking if
there are any sub-shard leaders to forward the update to
*Fix for SPLITSHARD (async) with failures in underlying
sub-operations can result in data loss
*Allow dynamic resizing of SolrCache-s
*Allow optional redaction of data saved by 'bin/solr autoscaling -save'

plugins on security.json change
*Fixed JWTAuthPlugin to update metrics prior to continuing w/other
filters or returning error
*Fixed distributed grouping when multiple 'fl' params are specified
*JMX MBeans are not exposed because of race condition between
creating platform mbean server and registering mbeans
*Fix for class-cast issues during atomic-update 'removeregex' operations
*Fix for multi-node race condition to create/remove nodeLost markers
*Fix for too many cascading calls to remote servers, which can bring
down nodes
*Fix for MOVEREPLICA ignoring replica type and always adding 'nrt'
*Fix: DistributedZkUpdateProcessor should propagate URP.finish()
