To install Python packages system-wide, try brew install
xyz, where xyz is the package you are trying to
install.
If you wish to install a Python library that isn't in Homebrew,
use a virtual environment:
python3 -m venv path/to/venv
source path/to/venv/bin/activate
python3 -m pip install xyz
If you wish to install a Python application that isn't in Homebrew,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. You can install pipx with
brew install pipx
You may restore the old behavior of pip by passing
the '--break-system-packages' flag to pip, or by adding
'break-system-packages = true' to your pip.conf file. The latter
will permanently disable this error.
If you disable this error, we STRONGLY recommend that you additionally
pass the '--user' flag to pip, or set 'user = true' in your pip.conf
file. Failure to do this can result in a broken Homebrew installation.
Read more about this behavior here: <https://peps.python.org/pep-0668/>

## Summary
Now that we perform this fast-path in
`crates/uv-distribution/src/source/mod.rs`, I _think_ the fast-path here
is no longer used? In my testing, we only actually took this path when
the fast-path _already_ failed (and thus it would fail again, wasting
time).

Regenerated the docs, with the fix.

## Summary
Fix incomplete value_type attribute for default-groups field in the
ToolUv struct schema definition. The value_type was missing its value,
which should be str | list[str] to reflect that default-groups can
accept either the literal "all" or a list of group names. (#16574)
Resolves https://github.com/astral-sh/uv/issues/16433
When `uv init` infers a project name from the working directory,
directories with characters outside the PEP 503 rules produced the
generic “Not a valid package or extra name” message that didn’t explain
the source of the problem. This change intercepts that failure, reports
whether the current or explicit target directory caused it, and tells
the user to supply an explicit `--name`.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This PR removes the crate fs2 and updates Rust version to 1.89.
*Why?*
Crate fs2 is unmaintained for a long time now and has unfixed issues.
Especially it doesn't build on AIX, which is the reason I started fixing
it.
*How?*
I removed fs2 and replaced it by std:fs:File methods.
## Test Plan
<!-- How was it tested? -->
- I built it on Windows and AIX only.
- I did not test the artifacts.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Implement `uv cache size` to output the cache directory size in raw
bytes by default, with a `--human` option for human-readable output.

## Summary
This is an enhancement that makes the cli flag `--no-sources` an
environment variable - "UV_NO_SOURCES"
Why is this a relevant change?
When working across different environments, in our case remote vs local,
we often have our packages hosted in a artifact registry but when
developing locally we build our packages from github. This results in us
using the uv.tool.sources table quite a bit however this then also
forces us to use `--no-sources` for all our remote work.
This change enables us to set an environment variable once and to never
have to type --no-sources after every uv run command again.
## Test Plan
Expanded on the current --no-sources tests, to test when
UV_NO_SOURCES=true/false the behaviour is the same as the flag.
Additionally ensured that the cli overrides the env variable.

Resolves https://github.com/astral-sh/uv/issues/16496
This PR updates the resolver so `build-system` dependency failures
surface prerelease hints even when prerelease selection is fixed. When a
build dependency only has prerelease candidates, or the requested
version explicitly includes a prerelease marker, we now emit a tailored
hint explaining that build environments can’t auto-enable prereleases
and describing how to opt in.

## Summary
Deserialize project name into both a String and a ProjectName, this way
we can keep using the normalized name elsewhere while respecting the
original name from the `pyproject.toml` file
This PR addresses issue #16547
## Test Plan
I added a new test for this, and I ran the test suite in the
`metadata.rs` file.

## Summary
This PR adds an `exclude-dependencies` setting that allows users to omit
a dependency during resolution. It's effectively a formalized version of
the `flask ; python_version < '0'` hack that we've suggested to users in
various issues.
Closes#12616.
It's too common to set `FORCE_COLOR` in CI which then breaks consumption
of the token.
This is actually specific to `pyx.dev`, as we print passwords without
coloring.
