In this release, I removed all implementation and documentation related to the Opera browser. The company that produces this browser has declined to publish a driver that fully supports the W3C protocol, which means that it can't be used with Selenium 4. I also removed the last vestige of support for PhantomJS.
I finally decided to resolve the deprecation warnings that Gradle would emit when executing build and test tasks. ChatGPT was very helpful in cleaning up my clunky Groovy implementation.
