" summary

Selenium 4 reduces jar size, deprecates DesiredCapabilities in favor of ChromeOptions/FirefoxOptions, and adds relative locators and improved window/tab APIs. Grid 4 rewrites Grid into microservices, uses a message bus, session queue and distributor, and adds observability via OpenTelemetry + Jaeger for end-to-end traces. Native CDP support enables network interception and geolocation mocking; WebDriver BiDi work brings cross‑browser CDP features. Selenium Manager (Rust) auto‑fetches drivers; downloads jump from ~25M to ~45M in one month.
