OxiCUDA 0.5.2 Released — PTX Portability Fixes for CUDA 12.9+, Windows, and a DMRG Correctness Bug
OxiCUDA 0.5.2 fixes a class of PTX portability bugs that CUDA 11.x silently tolerated and CUDA 12.9+ toolchains reject outright (non-ASCII bytes in generated comments), closes several Windows-specific test and lock-contention bugs, and fixes a numerical-correctness bug in the tensor-network DMRG excited-states solver. 38,675 tests, ~1.30M SLoC, 74 crates.
