+  commit_message: |
+    Upgrade to CUDA 12.9
+
+    CUDA 12.8 added support for architectures `sm_100`, `sm_101` and `sm_120`,
+    while CUDA 12.9 further added `sm_103` and `sm_121`. To build for these,
+    maintainers will need to modify their existing list of specified architectures
+    (e.g. `CMAKE_CUDA_ARCHITECTURES`, `TORCH_CUDA_ARCH_LIST`, etc.)
+    for their package. A good balance between broad support and storage
+    footprint (resp. compilation time) is to add `sm_100` and `sm_120`.
+
+    Since CUDA 12.8, the conda-forge nvcc package now sets `CUDAARCHS`
+    in its activation script to a string containing all
+    of the supported real architectures plus the virtual architecture of the
+    latest. Recipes for packages who use these variables to control their build
+    but do not want to build for all supported architectures will need to override
+    these variables in their build script.
