## 0.2.0

Starting with this release, uv will use the **minor** version tag to indicate breaking changes.

### Breaking

In this release, discovery of Python interpreters has changed. These changes should have a limited effect in most use-cases, however, it has been marked as a breaking change because the interpreter used by uv could change in some edge cases.

When multiple Python interpreters are installed, uv makes an attempt to find the exact version you requested. Previously, uv would stop at the first Python interpreter it discovered — if the interpreter did not satisfy the requested version, uv would fail. Now, uv will query multiple Python interpreters until it finds the requested version, skipping interpreters that are broken or do not satisfy the request.

Additionally, uv now allows requests for interpreter implementations such as `pypy` and `cpython`. For example, the request `--python cpython` will ignore a `python` executable that's implemented by `pypy`. These requests may also include a version, e.g., `--python pypy@3.10`. By default, uv will accept *any* interpreter implementation.

In summary, the following Python interpreter requests are now allowed:

- A Python version without an implementation name, e.g., `3.10`
- A path to a directory containing a Python installation, e.g., `./foo/.venv`
- A path to a Python executable, e.g., `~/bin/python`
- A Python implementation without a version, e.g., `pypy` or `cpython`
- A Python implementation name and version, e.g., `pypy3.8` or `pypy@3.8`
- The name of a Python executable (for lookup in the `PATH`), e.g., `foopython3`

Previously, interpreter requests that were not versions or paths were always treated as executable names.

To align the user expectations, uv now respects the interpreter that starts it. For example, `python -m uv ...` will now prefer the `python` interpreter that was used to start uv instead of searching for a virtual environment.

We now check if discovered interpreters are virtual environments. This means that setting `VIRTUAL_ENV` to a Python installation directory that is *not* a virtual environment will no longer work. Instead, use `--system` or `--python <path>` to request the interpreter.
