0. Intro and Solr PMC announcements

Welcome to the Apache Solr Newsletter Month YearOctober 2023 edition.

1. Current versions

• Apache Solr 9.4.0 released
  

  ### Solr 9.4.0 Release Highlights:

   * The Lucene version used by Solr has been upgraded to 9.8 – see its
  release notes.
   * The Jetty version has been updated to 10.0.17 to address CVE-2023-44487
   * Added support for node-level caches
   * Circuit Breakers available for Update Requests
   * A new Circuit breaker for percentage of CPU utilization is added. The
  former "CPU" circuit breaker is now more correctly named
  LoadAverageCircuitBreaker as it trips on system load average which is not a
  percentage.
   * Solr now includes an always-on trace id generator. This will inject
  trace id headers for every Solr request, propagating the client supplied
  value or generating a new id as needed and replaces the existing `rid`
  mechanism.
   * Solr now limits the number of concurrent expensive core operations (such
  as "backup", "restore", and "split") that are submitted asynchronously by
  running them in a dedicated thread pool.
   * Added support of OAuth 2.0/OIDC 'code with PKCE' flow
   * Multiple bug fixes for TLS and mTLS
  
  Thanks Alex Deparvu for the release.
