Yes, currently the Selenium 3.0 is working all around. According to their GitHub, it contains the following improvements:-
It has migrated all drivers to use the status strings rather than status codes in responses.
Update client bindings to also cope with that.
Write a new runner for the HTML-suite tests.
Segment the build to remove RC.
Using WebDriver after quit() should be an IllegalStateException.
Actions to have a single endpoint.
Capabilities to be the same as the spec.
Multiple calls to WebDriver.quit() should still be safe.
The new version will clean up WebDriver constructors, pulling heavy initialization logic into a Builder class.
Migrate to Netty or webbite server.
Delete unnecessary cruft.
Land a cleaner endpoint for the RC emulation.
