  • The property blockUnknown in the BasicAuthPlugin and the JWTAuthPlugin now defaults to true instead of false.

  • Solr now runs with the Java security manager enabled by default. Hadoop users may need to disable this
  • Solr embedded zookeeper only binds to localhost by default. See Upgrade Notes for how to obtain old behavior.

  • The "dist" folder in the release is gone. Module jars are now inside respective module's lib/ folder

  • Jetty Request log is now enabled by default, i.e. logging every request
