Whether or not an upgrade to Selenium 4 is done depends on a few factors:

**Project Requirements**: Features like improved debugging facilities or support for the most modern web applications may justify an upgrade to Selenium 4.

**Existing Test Suites**: Consider the number of test scripts running on Selenium 3. Since Selenium 4 is backward compatible, the transition should be smooth, though the effort involved in the transition should be factored in.

**Expertise**: Your team needs proper preparation to make productive and optimal use of the new features and changes provided with Selenium 4.
