When CUDA headers cannot be + found via site-packages, Conda, or ``CUDA_HOME``/``CUDA_PATH``, the system + now attempts to discover the CTK root via canary probing (using a + system-loaded ``cudart`` library path) and searches the CTK include layout + from that root. This improves header discovery in standard and non-standard + CTK installations, including containerized environments. + (`PR #1731 `_) + +* Add support for loading CUPTI (CUDA Profiling Tools Interface) dynamic libs + via ``load_nvidia_dynamic_lib("cupti")`` on Linux and Windows. CUPTI libraries + are discovered in site-packages (CUDA 12 and 13), Conda environments, and + CTK installations (via CUDA_HOME/CUDA_PATH or canary probe). + Supports ``libcupti.so.12``, ``libcupti.so.13`` on Linux and versioned + ``cupti64_*.dll`` files on Windows. + (`PR #1693 `_) + +* Add support for finding static libraries (e.g., ``libcudadevrt.a`` on Linux, + ``cudadevrt.lib`` on Windows) via new ``find_static_lib()`` and + ``locate_static_lib()`` APIs. These follow the same search order as bitcode + libraries: site-packages, Conda, then CUDA_HOME/CUDA_PATH. + (`PR #1690 `_) + +* Fix site-packages search order for virtual environments created with + ``--system-site-packages``. The search now correctly prioritizes the venv's + site-packages before user-site-packages, conforming to PEP 405. + (`PR #1717 `_) + +Internal refactoring +-------------------- + +* Refactor library discovery and loading to use a descriptor-driven architecture. + All library metadata (SONAMEs, DLLs, site-packages paths, dependencies, loader + flags) is now consolidated into a single ``LibDescriptor`` registry, improving + maintainability and extensibility. This is an internal refactoring with no + behavioral changes. + (`PR #1685 `_)
