+============================================
+
+This release contains mostly improvements to code robustness and testing, 
+including evolving internal code implementations to use C++17.
+
+Notable changes include:
+
+  * New features / API changes:
+
+  * Build changes/improvements:
+    * Update Camp submodule to v2025.12.0 release.
+    * Improve CMake support for configuring with Caliper and fix issue reported
+      by a user.
+    * Bump minimum CMake version required to 3.24.

+  * Bug fixes/improvements:
+    * Fix compilation failue when a downstream library or applications is
+      built without OpenMP enabled when RAJA was built with OpenMP enabled.
+      There may still be some corner cases that violate C++ ODR that we have not
+      resolved and are not being exposed by users.
