+# What’s new in Grafana v11.4
+
+Welcome to Grafana 11.4! This is a special release with one new feature, created in partnership with AWS. We’ve made improvements to Cloudwatch so you can query your logs using two additional query languages: Opensearch PPL and Opensearch SQL. We’ve also updated the querying experience by providing a sample of commonly-used queries, syntax highlighting in the query editor, and auto-completion suggestions for complex queries. Read on to learn more about this new feature.
+
+For even more detail about all the changes in this release, refer to the [changelog](https://github.com/grafana/grafana/blob/main/CHANGELOG.md). For the specific steps we recommend when you upgrade to v11.4, check out our [Upgrade Guide](https://grafana.com/docs/grafana/<GRAFANA_VERSION>/upgrade-guide/upgrade-v11.4/).

+## Query Cloudwatch Logs Insights with PPL and SQL
+
+<!-- Ida Štambuk, Zoe Chou -->
+
+_Generally available in all editions of Grafana_
+
+The AWS CloudWatch data source plugin now offers two new query languages for searching through logs: OpenSearch PPL and OpenSearch SQL. You now have increased flexibility to choose a more familiar query language and to take advantage of their unique features (like the SQL JOIN command) when querying AWS CloudWatch Logs Insights. In addition to the already supported **Logs Insights QL** option, you can find the added query language options in the new **Query language** drop-down list.

+
+We’ve also updated the query editor to support syntax highlighting and to provide suggestions while you type, which simplifies writing complex queries. When you select log groups, the suggestions also include [discovered fields](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CWL_AnalyzeLogData-discoverable-fields.html).
+
+Not sure where to start? We’ve also updated our **CloudWatch Logs cheat sheet** with the most commonly used queries so you can paste and customize to fit exactly what you need. Clicking on any of the example queries prefills the query input field.
