# Changelog 0.7.x
## 0.7.0
This release contains various changes that improve correctness and user experience, but could break
some workflows; many changes have been marked as breaking out of an abundance of caution. We expect
most users to be able to upgrade without making changes.
### Breaking changes
- **Update `uv version` to display and update project versions
([#12349](https://github.com/astral-sh/uv/pull/12349))**
Previously, `uv version` displayed uv's version. Now, `uv version` will display or update the
project's version. This interface was
[heavily requested](https://github.com/astral-sh/uv/issues/6298) and, after much consideration, we
decided that transitioning the top-level command was the best option.
Here's a brief example:
```console
$ uv init example
Initialized project `example` at `./example`
$ cd example
$ uv version
example 0.1.0
$ uv version --bump major
example 0.1.0 => 1.0.0
$ uv version --short
1.0.0
```
If used outside of a project, uv will fallback to showing its own version still:
```console
$ uv version
warning: failed to read project: No `pyproject.toml` found in current directory or any parent directory
running `uv self version` for compatibility with old `uv version` command.
this fallback will be removed soon, pass `--preview` to make this an error.
uv 0.7.0 (4433f41c9 2025-04-29)
```
As described in the warning, `--preview` can be used to error instead:
```console
$ uv version --preview
error: No `pyproject.toml` found in current directory or any parent directory
```
The previous functionality of `uv version` was moved to `uv self version`.
- **Avoid fallback to subsequent indexes on authentication failure
([#12805](https://github.com/astral-sh/uv/pull/12805))**
When using the `first-index` strategy (the default), uv will stop searching indexes for a package
once it is found on a single index. Previously, uv considered a package as "missing" from an index
during authentication failures, such as an HTTP 401 or HTTP 403 (normally, missing packages are
represented by an HTTP 404). This behavior was motivated by unusual responses from some package
indexes, but reduces the safety of uv's index strategy when authentication fails. Now, uv will
consider an authentication failure as a stop-point when searching for a package across indexes.
The `index.ignore-error-codes` option can be used to recover the existing behavior, e.g.:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"
ignore-error-codes = [401, 403]
```
Since PyTorch's indexes always return a HTTP 403 for missing packages, uv special-cases indexes on
the `pytorch.org` domain to ignore that error code by default.
- **Require the command in `uvx <name>` to be available in the Python environment
([#11603](https://github.com/astral-sh/uv/pull/11603))**
Previously, `uvx` would attempt to execute a command even if it was not provided by a Python
package. For example, if we presume `foo` is an empty Python package which provides no command,
`uvx foo` would invoke the `foo` command on the `PATH` (if present). Now, uv will error early if
the `foo` executable is not provided by the requested Python package. This check is not enforced
when `--from` is used, so patterns like `uvx --from foo bash -c "..."` are still valid. uv also
still allows `uvx foo` where the `foo` executable is provided by a dependency of `foo` instead of
`foo` itself, as this is fairly common for packages which depend on a dedicated package for their
command-line interface.
- **Use index URL instead of package URL for keyring credential lookups
([#12651](https://github.com/astral-sh/uv/pull/12651))**
When determining credentials for querying a package URL, uv previously sent the full URL to the
`keyring` command. However, some keyring plugins expect to receive the _index URL_ (which is
usually a parent of the package URL). Now, uv requests credentials for the index URL instead. This
behavior matches `pip`.
- **Remove `--version` from subcommands ([#13108](https://github.com/astral-sh/uv/pull/13108))**
Previously, uv allowed the `--version` flag on arbitrary subcommands, e.g., `uv run --version`.
However, the `--version` flag is useful for other operations since uv is a package manager.
Consequently, we've removed the `--version` flag from subcommands — it is only available as
`uv --version`.
- **Omit Python 3.7 downloads from managed versions
([#13022](https://github.com/astral-sh/uv/pull/13022))**
Python 3.7 is EOL and not formally supported by uv; however, Python 3.7 was previously available
for download on a subset of platforms.
- **Reject non-PEP 751 TOML files in install, compile, and export commands
([#13120](https://github.com/astral-sh/uv/pull/13120),
[#13119](https://github.com/astral-sh/uv/pull/13119))**
Previously, uv treated arbitrary `.toml` files passed to commands (e.g.,
`uv pip install -r foo.toml` or `uv pip compile -o foo.toml`) as `requirements.txt`-formatted
files. Now, uv will error instead. If using PEP 751 lockfiles, use the standardized format for
custom names instead, e.g., `pylock.foo.toml`.
- **Ignore arbitrary Python requests in version files
([#12909](https://github.com/astral-sh/uv/pull/12909))**
uv allows arbitrary strings to be used for Python version requests, in which they are treated as
an executable name to search for in the `PATH`. However, using this form of request in
`.python-version` files is non-standard and conflicts with `pyenv-virtualenv` which writes
environment names to `.python-version` files. In this release, uv will now ignore requests that
are arbitrary strings when found in `.python-version` files.
- **Error on unknown dependency object specifiers
([12811](https://github.com/astral-sh/uv/pull/12811))**
The `[dependency-groups]` entries can include "object specifiers", e.g. `set-phasers-to = ...` in:
```toml
[dependency-groups]
foo = ["pyparsing"]
bar = [{set-phasers-to = "stun"}]
```
However, the only current spec-compliant object specifier is `include-group`. Previously, uv would
ignore unknown object specifiers. Now, uv will error.
- **Make `--frozen` and `--no-sources` conflicting options
([#12671](https://github.com/astral-sh/uv/pull/12671))**
Using `--no-sources` always requires a new resolution and `--frozen` will always fail when used
with it. Now, this conflict is encoded in the CLI options for clarity.
- **Treat empty `UV_PYTHON_INSTALL_DIR` and `UV_TOOL_DIR` as unset
([#12907](https://github.com/astral-sh/uv/pull/12907),
[#12905](https://github.com/astral-sh/uv/pull/12905))**
Previously, these variables were treated as set to the current working directory when set to an
empty string. Now, uv will ignore these variables when empty. This matches uv's behavior for other
environment variables which configure directories.

### Documentation
- Clarify adding SSH Git dependencies ([#13534](https://github.com/astral-sh/uv/pull/13534))
## 0.7.8
### Python
We are reverting most of our Python changes from `uv 0.7.6` and `uv 0.7.7` due to a miscompilation
that makes the Python interpreter behave incorrectly, resulting in spurious type-errors involving
str. This issue seems to be isolated to x86_64 Linux, and affected at least Python 3.12, 3.13, and
3.14.
The following changes that were introduced in those versions of uv are temporarily being reverted
while we test and deploy a proper fix for the miscompilation:
- Add Python 3.14 on musl
- free-threaded Python on musl
- Add Python 3.14.0a7
- Statically link `libpython` into the interpreter on Linux for a significant performance boost
See [the issue for details](https://github.com/astral-sh/uv/issues/13610).
### Documentation
- Remove misleading line in pin documentation ([#13611](https://github.com/astral-sh/uv/pull/13611))

## 0.7.19
The **[uv build backend](https://docs.astral.sh/uv/concepts/build-backend/) is now stable**, and
considered ready for production use.
The uv build backend is a great choice for pure Python projects. It has reasonable defaults, with
the goal of requiring zero configuration for most users, but provides flexible configuration to
accommodate most Python project structures. It integrates tightly with uv, to improve messaging and
user experience. It validates project metadata and structures, preventing common mistakes. And,
finally, it's very fast — `uv sync` on a new project (from `uv init`) is 10-30x faster than with
other build backends.
To use uv as a build backend in an existing project, add `uv_build` to the `[build-system]` section
in your `pyproject.toml`:
```toml
[build-system]
requires = ["uv_build>=0.7.19,<0.8.0"]
build-backend = "uv_build"
```
In a future release, it will replace `hatchling` as the default in `uv init`. As before, uv will
remain compatible with all standards-compliant build backends.
