WalkthroughThe project moves from RAPIDS 26.10 to 26.12. The change updates release metadata, dependency constraints, CUDA environments, development containers, CI images, Java examples, and package requirements. Changes26.12 release alignment
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🟡 Moderate · up to This release-alignment change updates version and dependency metadata to 26.12, but release documentation still names an unavailable SNAPSHOT artifact and the C++ test dependencies retain a 26.10 streaming package. The dependency mismatch should be corrected before merge to keep the release test environment installable and version-consistent. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@dependencies.yaml`:
- Line 1140: Keep libcudf-streaming-tests pinned to a version currently
published by the rapidsai channel, rather than updating it to 26.12.* before
that package is available; align the pin with the resolved package version while
preserving the existing dependency constraint format.
In `@java/ci/README.md`:
- Line 102: Update the release artifact example in the JAR documentation to use
a release-versioned filename without the -SNAPSHOT suffix, consistent with
build_cudf_java_jar_in_container.sh removing that suffix during packaging.

Resolve the libcudf-streaming-tests package version before updating this pin.
libcudf-streaming-tests==26.10.* does not match the other test_cpp_cudf packages. The rapidsai channel currently publishes only 26.08.* for this package, so changing the pin to 26.12.* would also fail until that package is published. Update this dependency after publishing a matching 26.12.* package.

The 26.12 RMM wheel is not yet available on the nightly index, so the mypy hook fails while creating its environment and never checks source. Keep this tooling-only dependency on the latest available 26.10 line while retaining the repository’s 26.12 runtime and build constraints.
The 26.12 rollover requires every RMM reference, including the mypy hook environment, to stay on the same release line. Revert the temporary 26.10 tooling exception so pre-commit configuration remains consistent with the repository’s 26.12 runtime and build metadata.
