The package exposes `Group`, `Handle`, `Tensor`, typed config dataclasses, `Algorithm`, `Layout`, `PassDir`, and the named input/output structs used by the NCCL EP API. - Added `nccl.core.device.cute`, enabling CuTeDSL kernels to call NCCL device APIs. - Added top-level stack diagnostics with `nccl.get_version()` and `nccl.show_versions()`, reporting `nccl4py`, `libnccl.so`, and `libnccl_ep.so` versions, CUDA build variants, and loaded shared-library paths. - Added free-threaded CPython support. New Features NCCL EP Python API - New `nccl.ep` package provides Pythonic access to the NCCL EP extension library. - `Group.create()` creates EP groups from a `Communicator` and `GroupConfig`; `Group.create_handle()` creates handles with an explicit `Layout`. - `Handle` supports `update()`, `dispatch()`, `combine()`, `complete()`, and `destroy()`. - `DispatchInputs`, `DispatchOutputs`, `CombineInputs`, `CombineOutputs`, and `LayoutInfo` provide..."},"evidence_pages":[],"related_signals":[{"id":"7ed0d906-6328-418f-b11c-41171ecce51b","url":"https://onlylabs.fyi/signals/7ed0d906-6328-418f-b11c-41171ecce51b","source_url":"https://github.com/NVIDIA/elements/releases/tag/%40nvidia-elements/cli-v2.1.0","title":"NVIDIA/elements @nvidia-elements/cli-v2.1.0","context":"NVIDIA/elements","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-13T01:12:56+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"},{"id":"ba1d7b29-28e4-4e29-83b8-c44c65d7c04e","url":"https://onlylabs.fyi/signals/ba1d7b29-28e4-4e29-83b8-c44c65d7c04e","source_url":"https://github.com/NVIDIA/elements/releases/tag/%40nvidia-elements/forms-v2.0.1","title":"NVIDIA/elements @nvidia-elements/forms-v2.0.1","context":"NVIDIA/elements","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-13T01:12:06+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"},{"id":"894293d8-62fd-4b24-9d71-a65ce2520b9c","url":"https://onlylabs.fyi/signals/894293d8-62fd-4b24-9d71-a65ce2520b9c","source_url":"https://github.com/NVIDIA/NeMo-Relay/releases/tag/0.4.0","title":"NVIDIA/NeMo-Relay 0.4.0","context":"NVIDIA/NeMo-Relay","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-13T01:06:33+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"},{"id":"05267e83-7d06-43cb-ac26-7fd03e51e89f","url":"https://onlylabs.fyi/signals/05267e83-7d06-43cb-ac26-7fd03e51e89f","source_url":"https://github.com/NVIDIA/gdrcopy/releases/tag/v2.6","title":"NVIDIA/gdrcopy v2.6","context":"NVIDIA/gdrcopy","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-13T00:07:43+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"},{"id":"d56505b9-7fad-43c1-9bff-fcbcaf0cb1f3","url":"https://onlylabs.fyi/signals/d56505b9-7fad-43c1-9bff-fcbcaf0cb1f3","source_url":"https://github.com/NVIDIA/nodewright/releases/tag/chart/v0.17.0","title":"NVIDIA/nodewright chart/v0.17.0","context":"NVIDIA/nodewright","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-12T22:41:02+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"},{"id":"d65953d2-7f92-455c-845b-3a50a32f9549","url":"https://onlylabs.fyi/signals/d65953d2-7f92-455c-845b-3a50a32f9549","source_url":"https://github.com/NVIDIA/nodewright/releases/tag/operator/v0.17.0","title":"NVIDIA/nodewright operator/v0.17.0","context":"NVIDIA/nodewright","kind":{"key":"release","label":"Release"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-12T21:07:11+00:00","first_seen_at":"2026-06-13T07:00:32.337474+00:00","date_source":"source"}]}
