+# Thrust 1.13.1 (CUDA Toolkit 11.5)
+
+Thrust 1.13.1 is a minor release accompanying the CUDA Toolkit 11.5.
+
+This release provides a new hook for embedding the `thrust::` namespace inside a
+custom namespace. This is intended to work around various issues related to
+linking multiple shared libraries that use Thrust. The existing `CUB_NS_PREFIX`
+and `CUB_NS_POSTFIX` macros already provided this capability for CUB; this
+update provides a simpler mechanism that is extended to and integrated with
+Thrust. Simply define `THRUST_CUB_WRAPPED_NAMESPACE` to a namespace name, and
+both `thrust::` and `cub::` will be placed inside the new namespace. Using
+different wrapped namespaces for each shared library will prevent issues like
+those reported in NVIDIA/thrust#1401.
+
+## New Features
+
+- NVIDIA/thrust#1464: Add `THRUST_CUB_WRAPPED_NAMESPACE` hooks.
+
+## Bug Fixes
+
+- NVIDIA/thrust#1488: Fix path to installed CUB in Thrust's CMake config files.
