 ### Known issues
 - For NVIDIA backend, `NV_IF_TARGET` and `THRUST_RDC_ENABLED` intend to substitute the `THRUST_HAS_CUDART` macro, which is now no longer used in Thrust (provided for legacy support only). However, there is no `THRUST_RDC_ENABLED` macro available for the HIP backend, so some branches in Thrust's code may be unreachable in the HIP backend.
 
-## (Unreleased) rocThrust 2.18.0 for ROCm 5.7
+## rocThrust 2.18.0 for ROCm 5.7
 ### Fixed 
 - `lower_bound`, `upper_bound`, and `binary_search` failed to compile for certain types.
 - Fixed issue where `transform_iterator` would not compile with `__device__`-only operators.
