v0.4.0

Compare Source

This release adds first-class support for Python projects that are not designed as Python packages (e.g., web applications, data science projects, etc.).

In doing so, it includes some breaking changes around uv's handling of projects. Previously, uv required that all projects could be built into distributable Python packages, and installed them into the virtual environment. Projects created by uv init always included a [build-system] definition and existing projects that did not define a [build-system] would use the legacy setuptools build backend by default.

Most users are not developing libraries that need to be packaged and published to PyPI. Instead, they're building applications using web frameworks, or running collections of Python scripts in the project's root directory. In these cases, requiring a [build-system] was confusing and error-prone. In this release, uv changes the default behavior to orient around these common use cases.

In summary, the major changes are:

• uv no longer attempts to package and install projects that do not define a [build-system].
  • While the project itself will not be installed into the virtual environment, its dependencies will still be included.
  • The previous behavior can be recovered by setting package = true in the [tool.uv] section of your pyproject.toml.
• uv init no longer creates a src/ directory or defines a [build-system] by default.
  • The previous behavior can be recovered with uv init --lib or uv init --app --package.
• uv allows and recommends including [project] definitions in virtual workspace roots.
  • Previously, the uv required the [project] section to be omitted.
• uv allows disabling packaging of projects, even if they define a [build-system], by setting package = false in the [tool.uv] section of your pyproject.toml.

See the latest documentation on build systems in projects for more details.
