Looks like the same bug as in #1992. I confirm that after this PR we fix them all: |

…#2047 - New feature: persistent program cache for Program.compile (InMemoryProgramCache, FileStreamProgramCache, make_program_cache_key). - Fix: graph kernel nodes now prevent kernel-argument GC. - Fix: DeviceEvents.__dealloc__ crash on uninitialized handle.

…anup (#2032) * Document cuda.core support policy Add support.rst covering versioning (SemVer), CUDA version support (dual major versions), Python version support (CPython EOL schedule), free-threading (experimental), and release cadence (bimonthly). Closes #2030 * Fix broken CCCL URLs and add missing cuda.bindings interfaces - Update cuda.coop and cuda.compute URLs from the old nvidia.github.io/cccl/python/{coop,compute} paths (now 404) to the current unstable doc paths. - Add nvFatbin and NVML to the cuda.bindings interface list. - Update all three synced files: README.md, cuda_python/DESCRIPTION.rst, and cuda_python/docs/source/index.rst. * Add missing entries to cuda.core 1.0.0 release notes Add new features (green contexts, system.Device NVML APIs, system.typing module, NVML enum re-wrapping), breaking changes (tensor bridge behavior, system.Device renames, privatized helper classes, UUID format change, removed enums), and bug fixes (is_managed for pool alloc, nvJitLink log error handling, NVML event set init, Device.arch unknown, empty field values, runtime error messages, wheel size reduction). * Update cuda.core docs for 1.0.0 GA - api.rst: replace pre-1.0 warning with stable-API statement and link to support policy. - install.rst: update free-threading version reference from 0.4.0 to 1.0.0. - nv-versions.json: add 1.0.0 entry for the version switcher dropdown. * Split cuda.core.system API reference into separate page Move the CUDA system information / NVML section from api.rst into a dedicated api_nvml.rst. The new page uses its own `.. module:: cuda.core.system` directive so autosummary entries no longer need the `system.` prefix. Added to index.rst toctree after api. * Remove algorithm and size details from make_program_cache_key docstring The Returns section exposed the hash algorithm and digest size, which are implementation details. Replace with "opaque bytes digest" so the public API contract does not pin these. See #2043 * Remove deprecated cuda.core.experimental namespace The cuda.core.experimental namespace was deprecated in v0.5.0 when all public APIs moved to the top-level cuda.core namespace. Remove the backward-compatibility shim and its test as promised for v1.0.0. * Add missing release note entries for #1912, #2041, #2047 - New feature: persistent program cache for Program.compile (InMemoryProgramCache, FileStreamProgramCache, make_program_cache_key). - Fix: graph kernel nodes now prevent kernel-argument GC. - Fix: DeviceEvents.__dealloc__ crash on uninitialized handle. * Update 1.0.0-notes.rst * expand support policy * wordsmith
