 ### New Features and Enhancements
 
+The following DIRK schemes now have coefficients accurate to quad precision:
+* `ARKODE_BILLINGTON_3_3_2`
+* `ARKODE_KVAERNO_4_2_3`
+* `ARKODE_CASH_5_2_4`
+* `ARKODE_CASH_5_3_4`
+* `ARKODE_KVAERNO_5_3_4`
+* `ARKODE_KVAERNO_7_4_5`
+
 The default value of `CMAKE_CUDA_ARCHITECTURES` is no longer set to `70` and is
 now determined automatically by CMake. The previous default was only valid for
 Volta GPUs while the automatically selected value will vary across compilers and
