<h1>CodeQL Action Changelog</h1>
<p>See the <a

page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>3.30.2 - 09 Sep 2025</h2>

<li>Fixed a bug which could cause language autodetection to fail. <a
href="https://redirect.github.com/github/codeql-action/pull/3084">#3084</a></li>
<li>Experimental: The <code>quality-queries</code> input that was added
in <code>3.29.2</code> as part of an internal experiment is now
deprecated and will be removed in an upcoming version of the CodeQL
Action. It has been superseded by a new <code>analysis-kinds</code>
input, which is part of the same internal experiment. Do not use this in
production as it is subject to change at any time. <a

+### Manifest file
+
+The `manifest-file` input allows you to specify a JSON manifest that lists available uv versions,
+architectures, and their download URLs. By default, this action uses the manifest file contained
+in this repository, which is automatically updated with each release of uv.
+
+The manifest file contains an array of objects, each describing a version,
+architecture, platform, and the corresponding download URL. For example:
+
+```json
+[
+  {
+    "version": "0.7.13",
+    "artifactName": "uv-aarch64-apple-darwin.tar.gz",
+    "arch": "aarch64",
+    "platform": "apple-darwin",
+    "downloadUrl": "https://github.com/astral-sh/uv/releases/download/0.7.13/uv-aarch64-apple-darwin.tar.gz"
+  },
+  ...
+]
+```
+
+You can supply a custom manifest file URL to define additional versions,
+architectures, or different download URLs.
+This is useful if you maintain your own uv builds or want to override the default sources.
+
+```yaml
+- name: Use a custom manifest file
+  uses: astral-sh/setup-uv@v6
+  with:
+    manifest-file: "https://example.com/my-custom-manifest.json"
+```
+
+> [!NOTE]
+> When you use a custom manifest file and do not set the `version` input, its default value is `latest`.
+> This means the action will install the latest version available in the custom manifest file.
+> This is different from the default behavior of installing the latest version from the official uv releases.
+
+### Add problem matchers
+
+This action automatically adds
+[problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md)
+for python errors.
+
+You can disable this by setting the `add-problem-matchers` input to `false`.
+
+```yaml
+- name: Install the latest version of uv without problem matchers
+  uses: astral-sh/setup-uv@v6
+  with:
+    add-problem-matchers: false
+```

 ## How it works

@@ -485,6 +603,28 @@ Some workflows need uv but do not need to access the repository content.
 But **if** you need to access the repository content, you have run `actions/checkout` before running `setup-uv`.
 Running `actions/checkout` after `setup-uv` **is not supported**.
 
+### Does `setup-uv` also install my project or its dependencies automatically?
+
+No, `setup-uv` alone wont install any libraries from your `pyproject.toml` or `requirements.txt`, it only sets up `uv`.
+You should run `uv sync` or `uv pip install .` separately, or use `uv run ...` to ensure necessary dependencies are installed.
+
+### Why is a changed cache not detected and not the full cache uploaded?
+
+When `setup-uv` starts it has to know whether it is better to download an existing cache
+or start fresh and download every dependency again.
+It does this by using a combination of hashes calculated on the contents of e.g. `uv.lock`.
+
+By calculating these hashes and combining them in a key `setup-uv` can check
+if an uploaded cache exists for this key.
+If yes (e.g. contents of `uv.lock` did not change since last run) the dependencies in the cache
+are up to date and the cache will be downloaded and used.
+
+Details on determining which files will lead to different caches can be read under
+[cache-dependency-glob](#cache-dependency-glob)
+
+Some dependencies will never be uploaded to the cache and will be downloaded again on each run
+as described in [disable-cache-pruning](#disable-cache-pruning)
