### 0.12.0

- Date: 2026-07-28
- Version: 0.12.0
- Original notes: https://github.com/astral-sh/uv/releases/tag/0.12.0
- Permalink: https://whatsnew.fyi/product/uv/releases/0.12.0

- **changed** — Projects created with uv init now declare a build system using uv_build and are packaged by default, with source code placed in src/ and a project.scripts entry included
- **removed** — Reject unsupported source distribution archive formats such as .tar.bz2 and .tar.xz, allowing only .tar.gz and legacy .zip formats
- **removed** — Reject wheel and ZIP archive entries compressed with bzip2, LZMA, or XZ compression methods, requiring stored, DEFLATE, or zstd compression
- **security** — Reject wheel files with case-insensitive variants of reserved interpreter names and wheel data files that could replace the Python interpreter
- **changed** — Change pre-release handling default mode from if-necessary-or-explicit to if-necessary, preferring stable releases and falling back to pre-releases only when no stable candidate satisfies constraints

##### Release Notes

Released on 2026-07-28.

Since we released uv [0.11.0](https://github.com/astral-sh/uv/releases/tag/0.11.0) in March, we've accumulated changes that improve correctness, safety, and compatibility with specifications, but could break some workflows. This release contains those changes; many have been marked as breaking out of an abundance of caution.

**We expect most users to be able to upgrade without making changes.**

There are no breaking changes to the configuration of the [uv build backend](https://docs.astral.sh/uv/concepts/build-backend/). If your `[build-system]` table includes an upper bound on `uv_build`, update it to allow `uv_build` 0.12, e.g., `uv_build>=0.11.32,<0.13`.

###### Breaking changes

- **Define build systems by default with `uv init`** ([#19197](https://github.com/astral-sh/uv/pull/19197))

  Projects created with `uv init` now declare a build system and are packaged by default. This was the default project layout all the way back in [v0.3](https://github.com/astral-sh/uv/releases/tag/0.3.0), but we found that the use of the `hatchling` build system was confusing to newcomers and consequently dropped use of a build system by default in [v0.4](https://github.com/astral-sh/uv/releases/tag/0.4.0). Since then, we've created our own build system (`uv_build`) with tight integration with uv and are excited to restore the default to a best-practice project layout.

  Previously, `uv init example` created an unpackaged layout containing `main.py` and a `pyproject.toml` without a build system. The project could declare dependencies but was not itself installed into its virtual environment.

  Now, `uv init example` defines a `[build-system]` using `uv_build`, places application source code in `src/example`, and includes a `[project.scripts]` entry named `example`. Defining a build system allows the project to be imported from tests or other code, installed as a dependency, and run as a command:

  ```console
  $ uv init example
  $ cd example
  $ uv run example
  Hello from example!
  ```

  Existing projects are unaffected. Use [`uv init --no-package example`](https://docs.astral.sh/uv/concepts/projects/init/#creating-a-project-without-a-build-system) to create the previous unpackaged layout without a build system.

  See the [project creation documentation](https://docs.astral.sh/uv/concepts/projects/init/#applications) for more details.

  This stabilizes the `packaged-init` preview feature.

- **Reject unsupported source distribution and wheel archive formats** ([#18927](https://github.com/astral-sh/uv/pull/18927))

  [PEP 625](https://peps.python.org/pep-0625/) requires [source distributions](https://docs.astral.sh/uv/concepts/resolution/#source-distribution) to use `.tar.gz` archives. Previously, uv also accepted legacy formats such as `.tar.bz2` and `.tar.xz`. Those formats are now rejected, including when referenced by an existing lockfile. Legacy `.zip` source distributions remain supported for backwards compatibility.

  Wheels and other ZIP archives can no longer contain entries compressed with bzip2, LZMA, or XZ. Entries must use the stored, DEFLATE, or zstd compression methods.

  Removing support for uncommon compression methods reduces uv's compression dependencies and the attack surface exposed when processing untrusted packages.

  You cannot opt out of this behavior. If you depend on a legacy source distribution that uses an unsupported format, we recommend rebuilding it as a `.tar.gz` archive and regenerating any lockfile containing references to the legacy archive.

- **Reject wheel files that could replace the Python interpreter** ([#20748](https://github.com/astral-sh/uv/pull/20748), [#20749](https://github.com/astral-sh/uv/pull/20749))

  uv already rejected wheel entry points named `python`, but case variants such as `Python` were still accepted. On case-insensitive filesystems, including common macOS and Windows setups, these entry points could overwrite the virtual
