+### Python architecture
+
+Use `python-arch` to set `UV_PYTHON_ARCH` for the rest of the job. This selects the Python
+architecture independently of the version, including versions requested by `.python-version`.
+An explicit architecture or interpreter path in a Python request takes precedence.
+
+```yaml
+- uses: astral-sh/setup-uv@main
+  with:
+    python-version: "3.14"
+    python-arch: x86_64
+- run: uv run --frozen pytest
+```
+
+The input overrides an existing `UV_PYTHON_ARCH` value. When it is omitted, the action respects
+`UV_PYTHON_ARCH` from the environment. Both forms require a uv version that supports the variable;
+the action reports an error if the installed version does not support it. The selected architecture
+is included in the [cache key](docs/caching.md#cache-key).

Kevin Stillhammer	18d369b23d	chore(deps): roll up Dependabot updates (#1101 ) ## Summary Roll up the remaining dependency changes from eight open Dependabot PRs against current `main`, without reverting newer workflow settings: - CodeQL init, analyze, and autobuild: 4.37.7 → 4.38.1 (#1097, #1096, #1095) - zizmor-action: 0.6.3 → 0.6.4 (#1085) - @biomejs/biome: 2.5.9 → 2.5.11, including its schema URL (#1075) - @types/node: 26.2.0 → 26.4.0 (#1074) - Jest: 30.4.2 → 30.5.0 (#1073) - js-yaml: 5.3.0 → 5.4.1 (#1072) All nine open Dependabot PRs had remaining dependency changes; none was a no-op. TypeScript 7.0.2 (#1029) is intentionally deferred with maintainer approval: ts-jest 29.4.11 requires TypeScript <7, and applying the update caused all 15 test suites to fail before running with `Cannot read properties of undefined (reading 'readFile')`. The lockfile was regenerated using npm install with scripts disabled. No runtime dependency entries changed, and repackaging produced no `dist/` changes. ## Validation Using Node 24.19.0 and npm 11.10.0: - `npm ci --ignore-scripts` - `npm run all` — passed; 15 test suites, 159 tests; Biome applied no fixes - `npm audit signatures` — all 353 audited packages have verified registry signatures; 38 have verified attestations - `actionlint .github/workflows/codeql-analysis.yml .github/workflows/test.yml` — passed - `uvx zizmor --no-progress --offline .github/workflows/codeql-analysis.yml .github/workflows/test.yml` — no findings - `git diff --check` — passed Refs: pi-session 01a15ec2-de1a-7557-a0bb-00369b0a4a10	2026-10-21 16:17:16 +02:00

Danny Ward	c97f06e356	fix: preserve cache error class names in save-cache bundle (#1093 ) ## Summary - Preserve class names in the save-cache bundle so `@actions/cache` error-name comparisons distinguish validation errors, benign cache-reservation races, and finalization errors correctly. - Add regression coverage that exercises the bundled `ValidationError`, `ReserveCacheError`, and `FinalizeCacheError` constructors. Fixes #1028 ## Verification - `npm run all` passed on Ubuntu 24.04 with Node 24.19.0: build, Biome, packaging, and all 159 tests across 15 suites. - `git diff --check` passed. The save-cache bundle increases by about 77 KB raw (14 KB gzip) to preserve the required names.	2026-10-15 14:57:07 +02:00

flange-ipb	b627d85691	docs: cache-dependency-glob matches relative to the working directory (#1092 ) Hello! In #498 the behaviour of the `cache-dependency-glob` flag changed from being relative to repository root to being relative to `working-directory`. This is not yet documented in README.md. [docs/caching.md](https://github.com/astral-sh/setup-uv/blob/f64d32b1cd6cc11405a74665b3dfb7bb86fea9f0/docs/caching.md#cache-dependency-glob) already documents this behaviour correctly.	2026-10-14 15:58:35 +02:00
zaniebotandzaniebot	f8c88970fc	Verify npm dependency signatures before builds (#1027 ) CI installs the locked npm dependency tree without running lifecycle scripts, but it does not verify registry signatures or available provenance attestations. Run `npm audit signatures` after installation in both the test and checksum-update workflows, before `npm run all` executes dependency tooling. The check follows npm's registry-signature support and verifies attestations when present; it does not require every dependency to publish provenance. Related: astral-sh/ruff-action#402 adds the same signature and provenance verification. astral-sh/setup-uv#1026 separately hardens `npm` install defaults.

Zanie Blue	b06acff4b6	Add `python-arch` support (#1079 ) Windows ARM64 jobs may need x64 Python independently of their Python version pin. Add `python-arch` to export `UV_PYTHON_ARCH` for subsequent steps and include the selected architecture in the uv and managed-Python cache keys. The input takes precedence over an inherited environment value, and unsupported uv versions fail before environment creation. Requires a uv release with `UV_PYTHON_ARCH` support.	2026-10-07 09:03:18 +02:00

Charlie Marsh	51fdd265d3	Use macOS 15 runners for tests (#1081 ) We move the `macos-14` test jobs to `macos-15` ahead of GitHub’s [October 5 brownout and November 2, 2026 retirement](https://github.com/actions/runner-images/issues/13518). We also remove the macOS 14 cache-key test case; the matrix already covers macOS 15.	2026-10-02 15:17:20 -05:00
