Features & Improvements

• Add optional shell completion via argcomplete. Install with pip install "pipenv[completion]" and activate once with eval "$(register-python-argcomplete pipenv)".

  Mistyped subcommand names now produce "Did you mean …?" suggestions using difflib, replacing the click_didyoumean vendor library. [#6619](https://github.com/pypa/pipenv/issues/6619) <https://github.com/pypa/pipenv/issues/6619>_

Bug Fixes

• Fix pylock.toml re-generation duplicating dependency_groups markers for develop packages. Each run of pipenv pylock --generate (or any command that rewrites the lock file) prepended the dependency_groups prefix even when it was already present, producing malformed markers like ('dev' in dependency_groups) and (('dev' in dependency_groups) and ...). This caused pipenv install to crash with a KeyError: 'dependency_groups' when evaluating environment markers. [#6621](https://github.com/pypa/pipenv/issues/6621) <https://github.com/pypa/pipenv/issues/6621>_

Vendored Libraries

• Remove vendored colorama. Rich's Console supersedes colorama's Windows ANSI escape code handling, and this was the last remaining usage in Pipenv. [#6621](https://github.com/pypa/pipenv/issues/6621) <https://github.com/pypa/pipenv/issues/6621>_

Removals and Deprecations

• Remove the vendored click and click_didyoumean libraries. The CLI has been rewritten to use Python's standard-library argparse, eliminating Pipenv's dependency on Click entirely. [#6619](https://github.com/pypa/pipenv/issues/6619) <https://github.com/pypa/pipenv/issues/6619>_
• Remove the vendored importlib-metadata and zipp libraries. Python 3.9 is end-of-life and Pipenv requires Python 3.10+, where importlib.metadata
