 ## [4.5.0](https://github.com/NVIDIA/cutlass/tree/main) (2026-03-27)
 
 ### CuTe DSL
-* New features
-  - Auto-deduced smem size for launching kernels
-  - Launch config `smem` now defaults to `None` for auto-calculating kernel shared memory usage, which is recommended unless manual control is required.
-  - Warnings will be raised when the manually set shared memory size is insufficient or exceeds the GPU maximum.
-  - The default shared memory usage calculation aligns with CUDA C++ static shared memory behavior, i.e. summing all allocations additively.
-  - An additional launch option `smem_merge_branch_allocs` is provided to merge shared memory allocations across mutually exclusive code branches, which is recommended for inlined mega-kernels to reduce total footprint.
-
 * Bug fixing and improvements
   - Improved source code correlation for profiling/debugging
