Release Notes

astral-sh/setup-uv (astral-sh/setup-uv)

v8.0.0: 🌈 Immutable releases and secure tags

Compare Source

This is the first immutable release of setup-uv 🥳

All future releases are also immutable, if you want to know more about what this means checkout the docs.

This release also has two breaking changes

New format for manifest-file

The previously deprecated way of defining a custom version manifest to control which uv versions are available and where to download them from got removed. The functionality is still there but you have to use the new format.

No more major and minor tags

To increase security even more we will stop publishing minor tags. You won't be able to use @v8 or @v8.0 any longer. We do this because pinning to major releases opens up users to supply chain attacks like what happened to tj-actions.

[!TIP]
Use the immutable tag as a version astral-sh/setup-uv@8.0.0
Or even better the githash astral-sh/setup-uv@cec208311dfd045dd5311c1add060b2062131d57

🚨 Breaking changes

🧰 Maintenance

v7.6.0: 🌈 Fetch uv from Astral's mirror by default

Compare Source

Changes

We now default to download uv from releases.astral.sh.
This means by default we don't hit the GitHub API at all and shouldn't see any rate limits and timeouts any more.

v7.5.0: 🌈 Use astral-sh/versions as version provider

Compare Source

No more rate-limits

This release addresses a long-standing source of timeouts and rate-limit failures in setup-uv.

Previously, the action resolved version identifiers like 0.5.x by iterating over available uv releases via the GitHub API to find the best match. In contrast, latest and exact versions such as 0.5.0 skipped version resolution entirely and downloaded uv directly.

The manifest-file input was an earlier attempt to improve this. It allows providing an url to a file that lists available versions, checksums, and even custom download URLs. The action also shipped with such a manifest.
However, because that bundled file could become outdated whenever new uv releases were published, the action still had to fall back to the GitHub API in many cases.

This release solves the problem by sourcing version data from Astral’s versions repository via the raw content endpoint:

https://raw.githubusercontent.com/astral-sh/versions/refs/heads/main/v1/uv.ndjson

By using the raw endpoint instead of the GitHub API, version resolution no longer depends on API authentication and is much less likely to run into rate limits or timeouts.


[!TIP]
The next section is only interesting for users of the manifest-file input

The manifest-file input lets you override that source with your own URL, for example to test custom uv builds or alternate download locations.

The manifest file must be in NDJSON format, where each line is a JSON object representing a version and its artifacts. For example:

{"version":"0.10.7","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
{"version":"0.10.6","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}

[!WARNING]
The old format still works but is deprecated. A warning will be logged when you use it.
