Deprecate delighted package - Delighted sunset June 30, 2026

[jflores-q]

Summary

Delighted is being sunset on June 30, 2026. This is the final release of the delighted Python package (v4.2.0), marking it as deprecated and inactive.

For more information, visit the Delighted Sunset FAQ.

Changes

• Version bump to 4.2.0 in delighted/__init__.py
• Added FutureWarning at import time in delighted/__init__.py, so users see a deprecation notice when they import delighted. Uses FutureWarning (not DeprecationWarning) because FutureWarning is visible by default in all Python environments. DeprecationWarning is suppressed by default for non-__main__ modules.
• Added deprecation banner to the top of README.md. setup.py uses the README as the PyPI package description, so this notice will appear prominently on the PyPI project page.
• Changed Development Status classifier from Production/Stable to Inactive in setup.py.
• Updated author_email from ben@delighted.com to hello@delighted.com in setup.py. The previous address belongs to a former team member. hello@delighted.com is the active Delighted support address.
• Added 4.2.0 entry to CHANGELOG.md.

This PR is good to merge. After merging, follow the post-merge steps:

1. Tag the release as v4.2.0
2. Build source distribution: python setup.py sdist
3. Upload to PyPI: twine upload dist/delighted-4.2.0.tar.gz
4. Archive the project on PyPI settings
5. Archive this GitHub repository

Local validation steps (reproduce the checks above)

1. Build the source distribution

python setup.py sdist

This creates dist/delighted-4.2.0.tar.gz. You'll see a SetuptoolsDeprecationWarning about setup.py. That's expected and harmless (the repo doesn't have a pyproject.toml).

2. Validate metadata with twine

pip install twine
twine check dist/delighted-4.2.0.tar.gz
# Expected: "Checking dist/delighted-4.2.0.tar.gz: PASSED"

3. Inspect the archive contents

tar tzf dist/delighted-4.2.0.tar.gz | head -20
# Confirm it contains: PKG-INFO, README.md, setup.py, delighted/__init__.py, etc.

4. Install locally and test the warning

pip install dist/delighted-4.2.0.tar.gz
python -c "import delighted" 2>&1

You should see:

<string>:1: FutureWarning: Delighted is being sunset on June 30, 2026. This package is deprecated
and will no longer be maintained or receive updates. For more information, visit the Delighted
Sunset FAQ: https://help.delighted.com/article/840-delighted-sunset-faq

FutureWarning is used instead of DeprecationWarning because Python suppresses DeprecationWarning by default for non-__main__ modules. FutureWarning is shown to all users in all environments.

Clean up after testing:

pip uninstall delighted -y

5. Verify PKG-INFO metadata

python -c "
import tarfile
with tarfile.open('dist/delighted-4.2.0.tar.gz') as t:
    info = t.extractfile('delighted-4.2.0/PKG-INFO')
    for line in info.read().decode().split('\n')[:15]:
        print(line)
"

Confirm the output includes:

• Version: 4.2.0
• Author-email: hello@delighted.com
• Classifier: Development Status :: 7 - Inactive
