Features & Improvements

• Add experimental workspace support for managing local member projects in a shared root lock file. (#​1505)
• Defer startup-time imports for Python, virtualenv, and self-management commands. (#​3673)

Bug Fixes

• Fix pdm completion bash printing __ltrim_colon_completions: command not found (and a similar error for _get_comp_words_by_ref) when the generated script is sourced in a bash without the bash-completion package loaded, such as Git Bash on Windows or minimal Linux containers. The script now defines small fallbacks for both helpers when they are not already available. (#​3793)
• Avoid forwarding duplicate SIGINT in pdm run on POSIX. (#​3808)

Documentation

• Fix the Windows installation instructions for a specific version. Invoke-Expression (iex) does not accept an -Args parameter and cannot forward arguments to a piped script, so the documented command failed. Use the $env:PDM_VERSION environment variable, which the install script reads, instead. (#​3792)
