• Updated Pipenv from 2024.0.1 to 2025.0.4. (#1840)
• Fixed the way Pipenv is installed, so that it and its dependencies are installed into a separate virtual environment rather than same environment as the app. If your app inadvertently depended on Pipenv's internal dependencies, you will need to add those dependencies explicitly to your Pipfile. (#1840)
• Stopped installing pip when Pipenv is the chosen package manager. (#1840)
• The build cache is now cleared when using Pipenv if the contents of Pipfile.lock has changed since the last build. This is required to work around Pipenv not uninstalling packages when they are removed from the lockfile. (#1840)
• The build now errors when using Pipenv without its lockfile (Pipfile.lock). This replaces the warning displayed since November 2024. (#1833)
