release: v3.6.1.0 (#100)

* release: v3.6.1.0

Bump the version to 3.6.1.0 for cuvis SDK 3.6.1 and raise the cuvis-il
requirement to >=3.6.1,<3.7.0. No API changes.

* test: match hashed .cu3sp sidecar names from SDK 3.6.1

SDK 3.6.1 writes target_spectrum_ref_<md5>.cu3sp instead of
target_spectrum_ref.cu3sp; the test hardcoded the 3.6.0 names.

* changelog: record the sidecar name test fix

 ## [Unreleased]
 
+## [3.6.1.0] - 2026-10-16
+
+Targets cuvis SDK 3.6.1.
+First wrapper release for that SDK.
+
+### Changed
+
+- `pyproject.toml` - the `cuvis-il` requirement is raised to `>=3.6.1,<3.7.0`.
+
+### Fixed
+
+- `tests/` - the legacy `.cu3` round-trip test failed against SDK 3.6.1, which appends a content hash to the reference spectrum sidecars (`target_spectrum_ref_<md5>.cu3sp`).
+  The sidecars are now matched by prefix, one per slot, so the test passes against SDK 3.6.0 and 3.6.1.
+
 ## [3.6.0.0] - 2026-09-11
 
 Targets cuvis SDK 3.6.0.
