by ADMIN 50 views

Introduction

As a developer, it's essential to stay up-to-date with the latest developments in the Python ecosystem. With the release of Python 3.13, it's time to bid farewell to Python 3.8, which has reached its end-of-life (EOL) on October 7th, 2024. In this article, we'll guide you through the process of removing support for Python 3.8 and adding Python 3.13 to your project. We'll cover the necessary updates to setup.py, CI, and changelog to ensure a smooth transition.

Why Remove Support for Python 3.8?

Python 3.8, released in 2020, was a significant update to the Python language, introducing several new features and improvements. However, with the passage of time, it's no longer receiving security updates or bug fixes. This means that any vulnerabilities discovered in Python 3.8 will not be addressed, putting your project at risk. Moreover, as new versions of Python are released, the gap between Python 3.8 and the latest versions will continue to grow, making it increasingly difficult to maintain compatibility.

Why Add Python 3.13?

Python 3.13, released on the same date as Python 3.8's EOL, marks a significant milestone in the Python ecosystem. This new version brings several exciting features, including improved performance, enhanced security, and better compatibility with modern libraries and frameworks. By adding Python 3.13 to your project, you'll be able to take advantage of these new features and ensure that your project remains secure and up-to-date.

Updating setup.py to Python > 3.8

To remove support for Python 3.8, you'll need to update your setup.py file to specify a minimum Python version of 3.9 or higher. This can be done by modifying the python_requires parameter in your setup() function.

from setuptools import setup

setup(
    python_requires='>=3.9',
    # ... other parameters ...
)

By setting the python_requires parameter to >=3.9, you're indicating that your project requires Python 3.9 or higher to run. This will prevent users from installing your project on Python 3.8 or earlier versions.

Updating CI to Drop Testing for Python 3.8 and Add Python 3.13

To update your CI pipeline to drop testing for Python 3.8 and add Python 3.13, you'll need to modify your CI configuration files. This typically involves updating the python parameter in your CI configuration to specify the new Python versions.

For example, if you're using GitHub Actions, you can update your github/workflows/ci.yml file as follows:

name: CI

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Set up Python 3.13
        uses: actions/setup-python@v2
        with:
          python-version: '3.13'
      - name: Install dependencies        run: |
          python -m pip install --upgrade pip
          pip install -r requirements.txt
      - name: Run tests
        run: |
          python -m unittest discover -s tests

By updating the python-version parameter to 3.13, you're indicating that your CI pipeline should use Python 3.13 to run your tests.

Mentioning the Change in the Changelog or Release Notes

Finally, don't forget to mention the change in your project's changelog or release notes. This will help users understand the impact of the change and ensure that they're aware of the new requirements.

For example, you can add a new entry to your changelog as follows:

## [3.14.0] - 2024-10-07

* Removed support for Python 3.8
* Added support for Python 3.13

By following these steps, you'll be able to remove support for Python 3.8 and add Python 3.13 to your project. This will ensure that your project remains secure and up-to-date, and that you're taking advantage of the latest features and improvements in the Python ecosystem.

Conclusion

Removing support for Python 3.8 and adding Python 3.13 is an essential step towards maintaining a secure and up-to-date project. By following the steps outlined in this article, you'll be able to update your setup.py file, CI pipeline, and changelog to reflect the new requirements. Remember to always stay up-to-date with the latest developments in the Python ecosystem to ensure that your project remains competitive and secure.
