Make the required changes to modules/mux/tools/api/mux.xml or the compiler interface in modules/compiler/include/compiler/*.h.

Update ${FUNCTION_PREFIX}_MAJOR_VERSION, ${FUNCTION_PREFIX}_MINOR_VERSION, and ${FUNCTION_PREFIX}_PATCH_VERSION in modules/mux/tools/api/mux.xml as appropriate.

1. Note that as long as the version number is in the 0.X.Y stage it is very unlikely that you will be updating the major number.

Configure CMake, making sure that all ComputeMux targets are enabled. This includes host which is enabled by default, the stub target which is enabled with the CA_STUB_ENABLED, and the RISC-V target which is enabled with the CA_RISCV_ENABLED cmake option.

Build the mux-api-generate target e.g., ninja mux-api-generate.

Update doc/modules/mux/changes.rst. The previous step will have generated an empty entry for the latest version.

Update any other relevant documentation (e.g., doc/specifications/mux-runtime-spec.rst and doc/specifications/mux-compiler-spec.rst).

Create a merge request with all changes. Make sure to include the ComputeMux Runtime API XML, mux and all target headers, compiler, and doc/modules/mux/changes.rst.
