Release Notes

The main purpose of the CESM1.0.4 release is to provide the community a version of CESM1 that supports the Thermosphere/Ionosphere extension of WACCM (WACCMX) and the the capability to configure cases using interannual forcing component sets (CIAF, DIAF, and GIAF). CESM1.0.4 also includes a "patch" to MPI_RSEND that improves cray-gemini interconnect performance on Cray XT6 machines, and it contains other enhancements, machine updates, and bug fixes, as noted in this section. Aside from these new features, the CESM1.0.4 release is an incremental release beyond CESM1.0.3.
