Selenium Manager

Selenium 4.0, released in October 2021, includes Selenium Manager which automatically handles driver downloads (ChromeDriver, GeckoDriver). No more manual driver installation or third-party tools like webdriver-manager.

Simplified Usage

python 
from selenium import webdriver
from selenium.webdriver.common.by import By

# Selenium 4: no need to specify driver path
driver = webdriver.Chrome()  # Selenium Manager handles it

driver.get('https://www.python.org')
title = driver.title
print(f'Title: {title}')

# New relative locator system
element = driver.find_element(By.CSS_SELECTOR, '#content')
print(element.text[:100])

driver.quit()
