2026.6.1 (2026-04-28)

pipenv 2026.6.1 (2026-04-28)

Bug Fixes

• Fix pipenv install corrupting existing inline-table or outline-table Pipfile entries (six = {version = "*"}, [packages.requests]). The locker was popping version/ref keys directly off the cached parsed_pipfile document, so subsequent writes emitted six = {} and dropped the version specifier from sibling packages. [#6657](https://github.com/pypa/pipenv/issues/6657) <https://github.com/pypa/pipenv/issues/6657>_

2026.6.0 (2026-04-27)

pipenv 2026.6.0 (2026-04-27)

Bug Fixes

• Fix pipenv shell breaking terminal input echo on Linux. The previous implementation toggled setecho(True/False) on the spawned child around its internal setup commands, which fought with the shell's own readline termios management — producing permanently-disabled echo (GH-6572) or double-echoed keystrokes (1234 → 11223344). fork_compat no longer touches pty termios; instead it drains the synchronisation sentinel from the pexpect buffer twice (once for the echoed command, once for its output) so nothing leaks into interact(). [#6633](https://github.com/pypa/pipenv/issues/6633) <https://github.com/pypa/pipenv/issues/6633>_
• pipenv run <command> -h <arg> now passes -h through to the command instead of showing pipenv's help. All arguments following run_command are captured verbatim via argparse REMAINDER, so flags like -h that pipenv itself also defines no longer collide with the wrapped command. [#6641](https://github.com/pypa/pipenv/issues/6641) <https://github.com/pypa/pipenv/issues/6641>_
• Fix ValueError: invalid literal for int() with base 10 when the Pipfile's [requires] section uses a PEP 440 specifier (e.g. python_version = ">=3.9"). Specifier values no longer produce a Python-version override; the running interpreter's actual version is used for marker evaluation instead. [#6645](https://github.com/pypa/pipenv/issues/6645) <https://github.com/pypa/pipenv/issues/6645>_
• Install-time marker filtering now evaluates environment markers against the target virtualenv's Python version rather than against the Python version that pipenv itself is running under. This prevents spurious Ignoring …: markers … don't match your environment warnings (and the corresponding missing installs) when pipenv sync --python X.Y is driven by a different system Python. [#6647](https://github.com/pypa/pipenv/issues/6647) <https://github.com/pypa/pipenv/issues/6647>_
• pipenv run now expands $PIPENV_PROJECT_DIR and other Pipenv-managed environment variables inside Pipfile script arguments before direct command execution, so project-relative script paths resolve correctly. [#6652](https://github.com/pypa/pipenv/issues/6652) <https://github.com/pypa/pipenv/issues/6652>_
