+Kestrel 2
+=========
+
+Kestrel 2 debuts at `Black Hat USA 2024`_. While maintaining the language
+syntax from Kestrel 1, we entirely redesign Kestrel 2 runtime to achieve better
+performance and more flexible syntax regarding entity, attribute, and relation
+representations.
+
+Key features of Kestrel 2:
+
+- Just-in-time compilation instead of interpretation
+
+- Lazy evaluation and the new ``EXPLAIN`` command
+
+- Data Lakehouse optimization with deeply nested query
+
+- OCSF and OpenTelemetry entity/attribute support besides STIX
+
+Kestrel 2 is currently in beta, learn more at `Kestrel runtime installation`_.
