+
+Today, we released Quarkus 3.15.4, our next maintenance release for the 3.15 LTS stream.
+
+This release contains bugfixes and documentation improvements.
+
+It should be a safe upgrade for anyone already using 3.15. However, as part of fixing a security issue,
+one small potentially breaking change had to be applied: https://github.com/quarkusio/quarkus/pull/45877[#45877].
+This may affect you if you consume Netty allocator metrics.
+
+== Update
+
+To update to Quarkus 3.15, we recommend updating to the latest version of the Quarkus CLI and run:
+
+[source,bash]
+----
+quarkus update --stream=3.15
+----
+
+Note that `quarkus update` can update your applications from any version of Quarkus (including 2.x) to Quarkus 3.15.
+
+== Full changelog
