Selenium 2.1 Released

Filed under: Releases — shs96c @ 11:03 pm GMT+0000

Now that Selenium 2 has been released, one of the goals of the project is to provide regular updates to our users and the community. The aim is for these updates to be small and manageable, incrementally addressing issues and problems raised by you. Selenium 2.1, which is launched today, marks the first of these regular, small releases.

Selenium 2.1 is largely focused on improving Grid with a host of minor improvements including better tracking of “orphaned” browser instances. There are also some bug fixes in the Firefox and IE WebDrivers, particularly when dealing with elements that are just off screen, and in making the Selenium RC emulation in the Java bindings more robust when confronted with pages that haven’t started loading.

As you can see, this is a “bite size” release, but we’d love to know: would you prefer these small, swift releases or larger ones? Please answer in the comments, or on the mailing list!


  1. I prefer small releases!!

  2. +1 for “bite size” releases, as long as each release is reflected in the Maven repo. We depend on the repo to update our instances of Selenium.

  3. +1 for the smaller bite size releases.

  4. Glad to see 2.1 so soon. Small, swift releases are much preferred. Ideally with changelogs, so I can tell whether the hassle of upgrading is worth it or not.

  5. Can we add social share button on this site? It would make it easy for us to share the post with others.

  9. Fast smaller versions is better than long waiting for large versions

  12. Smaller release would be better

  13. Releases available in the maven repository even better

  14. Small updates, released frequently, with thorough change logs would be desirable.

  15. I agree that small releases not only address potential issues faster, but it also makes it easier to pin-point what has changed if a new version alters the result of existing tests.

  16. I thought this question was definitively answered in the 90’s: 🙂
    Thank you for a great piece of software, and thank you for making my job easier!

  17. Small and continuously like Mr. Fowler says 😉

  18. +1 for quicker/smaller releases. To me this means bugs and issues can be addressed more quickly.

    +999999 for getting Maven artifacts release in lock-step with the other binaries. (sorry to beat the proverbial dead horse 😉

  19. Does this can be used with perl?

  20. Hi All,

    I would prefere a “medium” releases, like 1 a month as we are using maven and every time we have to update the pom file!


    Comment by martino — July 20, 2011 @ 7:27 am GMT+0000 | Reply

  21. +1 for medium releases (about once a month).

    What’s new in 2.1.0 ?
    You definitively need a Changelog page!!

    • We’ll add a changelog to the source with 2.2, but this blog entry really does contain the major changes.

  22. My main concern is quality. Quick is fine as long as the QA process is rigorous. We use the application for QA ourselves, any quality issues in selenium would muck up that process.

  23. small, regular updates are good to keep the community of users active and encourage more usage which inturn boosts the developer community’s satisfaction. just a thought

  24. +1 for Quick is fine as long as the QA process is rigorous.

  25. Small releases is a great idea. Also can we add a wordpress share to the blog?

  26. I definitely prefer these short release which makes the bug fixes into users very quickly. Dont want to wait for too long 🙂

  27. Count me in for small and swift! Great job!

  28. I tried to upgrade to Selenium 2.1 yesterday and it was an incredibly confusing and frustrating process. Just changing the Maven dependencies did not do it – received many NoClassDefFound errors until I stumbled across someone’s entry in a forum about having to include the jars in the libs folder. After that, I ran into other issues with my tests built on the previous version of WebDriver. It would be EXTREMELY helpful if there was one location to go to for detailed documentation. I found there seemed to be many new classes and functions in the upgrade (Capabilities, for example – big for IE 8 users). I googled til my fingers bled and could not find adequate documentation explaining the new features and how to use them.

    A+ on the product, F– on the documentation. If someone knows of a good resource online, I’ll happily retract my comments.

    • The information for maven users to get the latest version of selenium is linked to from project’s download page:

      • I only want to use the WebDrivers. I can update the versions of the WebDrivers just fine, it’s all the other dependencies for the jar files in libs folder that was the issue. Like I said, I got past all that and was able to build properly. However, once I try to run tests, I run into other issues (like the IE Capabilities problem) that I didn’t know about because I can’t find any detailed documentation on the new features.

  29. Filling out the form seems to work, but now I get this error when I click “Save”:

    org.openqa.selenium.WebDriverException: session c031afa0-480c-4c12-895f-135ea1809f2d does not exist
    Build info: version: ‘2.2.0’, revision: ‘13073’, time: ‘2011-07-26 00:54:48’
    System info: ‘Windows 7’, os.arch: ‘amd64’, os.version: ‘6.1’, java.version: ‘1.6.0_18’
    Driver info: driver.version: RemoteWebDriver
