+# What’s new in Grafana v11.5
+
+Welcome to Grafana 11.5!
+Read on to learn about new sharing, reporting, and export options, cross-cluster search for Elasticsearch, PDC support for several new data sources, and more.
+The Grafana Cloud Migration Assistant is in public preview and now supports all plugins and Grafana Alerts, in addition to dashboards, folders, and data sources.
+We've also made it more secure to run third-party apps and data sources, and improved user session handling for OAuth 2.0 and SAML.
