What is the current stable version of urllib3?

The current stable version of urllib3 can be checked using several methods. Since package versions change frequently, here are the most reliable ways to find the latest stable version:

Method 1: Check via PyPI (Recommended)

The Python Package Index (PyPI) is the official source for package information:

  1. Visit the official PyPI website: https://pypi.org/project/urllib3/
  2. The latest stable version is displayed prominently at the top of the page
  3. You can also see the release history and download statistics

Method 2: Using pip Commands

Check Installed Version

If you already have urllib3 installed, check its version:

pip show urllib3

This displays detailed package information including the installed version.

Check Latest Available Version

To see the latest version available for installation without installing it:

pip index versions urllib3

Alternative Method (for older pip versions)

If the above command doesn't work, use this trick:

pip install urllib3==nonexistent

This will fail but show all available versions, with the latest at the bottom.

Method 3: Using Python Code

You can check the version programmatically:

import urllib3
print(urllib3.__version__)

Or check the latest version available on PyPI:

import requests
response = requests.get('https://pypi.org/pypi/urllib3/json')
latest_version = response.json()['info']['version']
print(f"Latest urllib3 version: {latest_version}")

Method 4: Check via GitHub

Visit the official urllib3 GitHub repository: - https://github.com/urllib3/urllib3 - Check the latest release in the "Releases" section

Method 5: Using pip list

To see all installed packages and their versions:

pip list | grep urllib3

To check for outdated packages:

pip list --outdated

Version Information

As of late 2024, urllib3 has two major version branches: - urllib3 v1.x: Legacy version with broader compatibility - urllib3 v2.x: Modern version with improved features and security

Important Notes

  • Always check the official PyPI page for the most current information
  • Consider your project's Python version compatibility when choosing urllib3 versions
  • urllib3 v2.x requires Python 3.7+ while v1.x supports older Python versions
  • For production environments, pin specific versions in your requirements.txt

Installing a Specific Version

Once you know the version you need:

# Install latest version
pip install urllib3

# Install specific version
pip install urllib3==2.0.7

# Upgrade to latest
pip install --upgrade urllib3
