Release notes

Sourced from click's releases.

8.3.1

This is the Click 8.3.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/click/8.3.1/ Changes: https://click.palletsprojects.com/page/changes/#version-8-3-1 Milestone: https://github.com/pallets/click/milestone/28

  • Don't discard pager arguments by correctly using subprocess.Popen. #3039 #3055
  • Replace Sentinel.UNSET default values by None as they're passed through the Context.invoke() method. #3066 #3065 #3068
  • Fix conversion of Sentinel.UNSET happening too early, which caused incorrect behavior for multiple parameters using the same name. #3071 #3079
  • Fix rendering when prompt and confirm parameter prompt_suffix is empty. #3019 #3021
  • When Sentinel.UNSET is found during parsing, it will skip calls to type_cast_value. #3069 #3090
  • Hide Sentinel.UNSET values as None when looking up for other parameters through the context inside parameter callbacks. #3136 #3137

8.3.0

This is the Click 8.3.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecation, or introduce potentially breaking changes.

We encourage everyone to upgrade. You can read more about our Version Support Policy on our website.

PyPI: https://pypi.org/project/click/8.3.0/ Changes: https://click.palletsprojects.com/page/changes/#version-8-3-0 Milestone https://github.com/pallets/click/milestone/27

  • Improved flag option handling: Reworked the relationship between flag_value and default parameters for better consistency:

    • The default parameter value is now preserved as-is and passed directly to CLI functions (no more unexpected transformations)
    • Exception: flag options with default=True maintain backward compatibility by defaulting to their flag_value
    • The default parameter can now be any type (bool, None, etc.)
    • Fixes inconsistencies reported in: #1992 #2514 #2610 #3024 #3030
  • Allow default to be set on Argument for nargs = -1. #2164 #3030

  • Show correct auto complete value for nargs option in combination with flag option #2813

  • Show correct auto complete value for nargs option in combination with flag option #2813

  • Fix handling of quoted and escaped parameters in Fish autocompletion. #2995 #3013

  • Lazily import shutil. #3023

  • Properly forward exception information to resources registered with click.core.Context.with_resource(). #2447 #3058

  • Fix regression related to EOF handling in CliRunner. #2939 #2940

8.2.2

This is the Click 8.2.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

## Summary

This changes the default for `prune-cache` from `true` to `false`,
motivated by [#745](astral-sh/setup-uv#745).
Users that want the existing behavior can continue to set `prune-cache:
true` explicitly.

Some history: I originally added [`uv cache prune
--ci`](astral-sh/uv#5391) after looking at a
workload where the uv cache was ~2.2 GB, almost entirely due to the
enormous pre-built `torch` and `nvidia_cudnn_cu12` wheels ([original
analysis](actions/setup-python#822 (comment))).
Persisting and restoring thousands of extracted files through the GitHub
Actions cache could be slower than downloading the wheels again. In
contrast, wheels built from source can be very expensive to recreate.
The intent was to remove pre-built wheels while retaining locally-built
wheels.

`setup-uv` subsequently made pruning configurable, but defaulted
`prune-cache` to `true`; it also later enabled caching by default on
GitHub-hosted runners. As a result, the default configuration repeatedly
downloads pre-built wheels from PyPI even on a cache hit. That tradeoff
has become more important as uv adoption has grown: [the PyPI analysis
in
#745](astral-sh/setup-uv#745 (comment))
estimates that uv accounts for roughly half of reported CI downloads
from PyPI, and roughly 65-75% for `boto3`.

I ran the comparison across a few different workloads:

The CUDA workload intentionally reproduces the original `torch==2.1.1`
example. Keeping wheels again produces a ~2.3 GB Actions cache. Across
nine warm runs, restoring that cache ranged from slightly faster than
re-downloading to roughly twice as slow; pruning consistently
re-downloaded 40 distributions in ~33-37 seconds ([original
runs](https://github.com/astral-sh/setup-uv-benchmarks/actions/runs/29750292738),
[additional
runs](https://github.com/astral-sh/setup-uv-benchmarks/actions/runs/29761705492)).

I also tried running `uv cache prune --force` without `--ci` across
every workload, to see if it provided a useful middle ground. It did not
meaningfully reduce any of the caches: plain prune took 11-21 ms and
left the extracted cache and file count unchanged, including PySpark. On
these fresh caches, there are no dangling entries to remove; without
`--ci`, the pre-built wheels and unpacked source/build artifacts are
retained. The per-workload runs are linked in the table above.

So the original motivation still holds for very large CUDA or
source-heavy workloads, but it is not representative of the common case.
For smaller workloads, keeping pre-built wheels is generally faster and
avoids repeated PyPI traffic. This changes the default accordingly,
while retaining `prune-cache: true` as an opt-in for workloads where the
smaller cache is worthwhile.

Closes astral-sh/setup-uv#745.

[additional

I also tried running `uv cache prune --force` without `--ci` across
every workload, to see if it provided a useful middle ground. It did not
meaningfully reduce any of the caches: plain prune took 11-21 ms and
left the extracted cache and file count unchanged, including PySpark. On
these fresh caches, there are no dangling entries to remove; without
`--ci`, the pre-built wheels and unpacked source/build artifacts are
retained. The per-workload runs are linked in the table above.

So the original motivation still holds for very large CUDA or
source-heavy workloads, but it is not representative of the common case.
For smaller workloads, keeping pre-built wheels is generally faster and
avoids repeated PyPI traffic. This changes the default accordingly,
while retaining `prune-cache: true` as an opt-in for workloads where the
smaller cache is worthwhile.

## Summary

This changes the default for `prune-cache` from `true` to `false`,
motivated by [#745](astral-sh/setup-uv#745).
Users that want the existing behavior can continue to set `prune-cache:
true` explicitly.

Some history: I originally added [`uv cache prune
--ci`](astral-sh/uv#5391) after looking at a
workload where the uv cache was ~2.2 GB, almost entirely due to the
enormous pre-built `torch` and `nvidia_cudnn_cu12` wheels ([original
analysis](actions/setup-python#822 (comment))).
Persisting and restoring thousands of extracted files through the GitHub
Actions cache could be slower than downloading the wheels again. In
contrast, wheels built from source can be very expensive to recreate.
The intent was to remove pre-built wheels while retaining locally-built
wheels.

`setup-uv` subsequently made pruning configurable, but defaulted
`prune-cache` to `true`; it also later enabled caching by default on
GitHub-hosted runners. As a result, the default configuration repeatedly
downloads pre-built wheels from PyPI even on a cache hit. That tradeoff
has become more important as uv adoption has grown: [the PyPI analysis
in
#745](astral-sh/setup-uv#745 (comment))
estimates that uv accounts for roughly half of reported CI downloads
from PyPI, and roughly 65-75% for `boto3`.

I ran the comparison across a few different workloads:
