We’re pleased to announce that Apache Solr Version 7.7.2 is now available on all SearchStax plans. You can create a new Solr 7.7.2 deployment by signing up for a 14-day free trial account OR by creating a new deployment in your existing account.

We made available Solr 7.5 in February. Improvements and Bug Fix highlights since Solr 7.5 include:

  • New Node-level health check handler at /admin/info/healthcheck and /node/health paths that checks if the node is live, connected to zookeeper and not shutdown.
