Releases on Selenium

Ending Support for Python 3.9

Wed, 08 Oct 2025 00:00:00 +0000

From the upcoming 4.37 release, Selenium will no longer support Python 3.9 in the Python WebDriver language bindings. To install the selenium package, you will need Python 3.10+.

Selenium will continue to support all versions of Python that are actively receiving bugfix and security updates from the Python core maintainers. The end-of-life for each major Python version is 5 years after its first release. For more information on supported Python versions, see the Python Developer’s Guide.

A Curious Case of Selenium Manager Usage: What's Behind Chrome 127.0.6533.99?

Sun, 14 Sep 2025 00:00:00 +0000

Over the past two years, Selenium has included Selenium Manager, a CLI tool (written in Rust) that provides automatic management of drivers and browsers across all official language bindings (Java, JavaScript, Python, .NET, and Ruby). Its purpose is to simplify the developer experience: if you create a driver object like this:

WebDriver driver = new ChromeDriver();

Selenium Manager takes care of detecting whether Chrome is installed, downloading the required driver, and even provisioning a copy of Chrome for Testing (CfT) if Chrome is not present on the system. This also works for Firefox and Edge, on Windows, Linux, and macOS.

Removing ChromeDevTools Support For Firefox

Mon, 03 Feb 2025 00:00:00 +0000

Selenium has deprecated support for Chrome DevTools Protocol (CDP) for Firefox in the last two versions (4.27 and 4.28). Our typical removal policy is to deprecate support for two versions, allowing users sufficient time to update their codebase, and then remove it from the third version onwards.

Starting with Selenium 4.29.0, CDP support for Firefox has been fully removed—and for good reason. Selenium’s CDP implementation for Firefox was always partial, meaning it never had complete feature parity with Chrome. Meanwhile, Firefox is shifting towards WebDriver BiDi, the future of cross-browser automation. Aligning with this, Firefox has announced that starting with Firefox 129, CDP will no longer be enabled by default. Read more here: [https://fxdx.dev/deprecating-cdp-support-in-firefox-embracing-the-future-with-webdriver-bidi/].

What's new in Selenium Manager 0.4.12, shipped with Selenium 4.12.0

Mon, 28 Aug 2023 00:00:00 +0000

A new release of Selenium Manager is out. For this release, we made a relevant decision concerning the Selenium Manager versioning format. From now on, Selenium Manager will follow the same version as Selenium. Nevertheless, since Selenium Manager is still in beta, its major version is 0. Thus, Selenium 4.12.0 is shipped with Selenium Manager 0.4.12.

First, we made a substantial effort to stabilize the already available features on Selenium Manager. This way, the version includes several bug-fixing related to automated driver management or caching. You can find the details of the changes implemented in Selenium Manager 0.4.12 in the (newly created) changelog file.

What's new in Selenium Manager with Selenium 4.11.0

Mon, 31 Jul 2023 00:00:00 +0000

As of version 4.6.0, all releases of Selenium (Java, JavaScript, Python, Ruby, and .Net) are shipped with Selenium Manager. Selenium Manager is a binary tool (implemented in Rust) that provides automated driver management for Selenium. Selenium Manager is still in beta, although it is becoming a relevant component of Selenium.

So far, the main feature of Selenium Manager is called automated driver management. I use the term management for this feature (and not just download) since this process is broader and implies different steps:

Building Selenium

Mon, 12 Jun 2023 00:00:00 +0000

One of the things that we knew from the very beginning of the Selenium project was that people like to code in more than one language. Some people love a bit of JS, others Ruby, and still others prefer C# or Java.

To complicate matters, there’s plenty of pieces we want to share between the language bindings you’ll be using. Examples include the “atoms” (re-usable pieces of javascript that perform common functions – such as “isDisplayed” or “getAttribute” – that we want to work the same way no matter which language you prefer to write tests in), things like our CDP support, which uses shared files that describe all the available functions we can call, and the new Selenium Manager, which is written in Rust, but we bundle with each of the language bindings.

Java 8 support in Selenium

Fri, 09 Jun 2023 00:00:00 +0000

“If it ain’t broke, don’t fix it” is a saying you may have heard, but sometimes it’s necessary to move on from our old favorites. That’s why we’re announcing that Selenium will stop supporting Java 8 on September 30, 2023. This applies for both the Java bindings and the Selenium Grid.

Selenium has long supported Java 8, but as technology evolves, so must we. One of the primary reasons for this change is that Java 8 reached the end of active support over a year ago. In addition, our default HTTP Client has not had a major release in several years, and a bug has been found that we can not fix. We have decided to move to the native Java HTTP Client, but it requires using Java 11 or greater. The sooner we make this change, the sooner we can avoid dealing with this issue.

Headless is Going Away!

Sun, 29 Jan 2023 00:00:00 +0000

Headless is an execution mode for Firefox and Chromium based browsers. It allows users to run automated scripts in headless mode, meaning that the browser window wouldn’t be visible. In most of Selenium’s bindings there is a convenience method to set this execution mode while setting the browser options. However, Selenium 4.8.0 will be deprecated this method and now users need to set it through arguments when setting the browser options.

Introducing Selenium Manager

Fri, 04 Nov 2022 00:00:00 +0000

Most people’s first experience with Selenium ends up with an error message like this one:

java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver 
system property; for more information, see https://chromedriver.chromium.org/. The latest version can be 
downloaded from https://chromedriver.chromium.org/downloads

Then they have to search the web for instructions on what to do with the drivers they download.

Selenium: now with batteries included!

The Selenium project wants to improve the user experience, and one of the first steps is to help all users to simplify how they set up their environment. Configuring browser drivers has been for many years a task which users need to perform in order to have a working environment to run Selenium.

Using Java 11+ HTTP Client in Selenium 4.5.0 and beyond

Fri, 16 Sep 2022 00:00:00 +0000

Current HTTP client used in Selenium

Selenium uses an HTTP client and associated WebSocket client for multiple purposes

To send commands to the WebDriver
To send commands from the Selenium client library to the Grid
For various Grid components to communicate with each other depending on the Grid mode
To create ChromeDevTools protocol and BiDi protocol sessions

Currently, Selenium uses AsyncHttpClient. AsyncHttpClient is an open-source library built on top of Netty. It allows the execution of HTTP requests and responses asynchronously. Additionally it also provides WebSocket support. Hence it is a good fit.

Selenium 4.4.0 Released!

Tue, 09 Aug 2022 00:00:00 +0000

We’re very happy to announce the release of Selenium 4.4.0. We’re shipping this for Java, .Net, Python, Ruby, and JavaScript, so if you’re using any of those languages, go and grab it from your package manager of choice!

Selenium 3.0: Out Now!

Thu, 13 Oct 2016 00:00:00 +0000

We are very pleased to announce the release of Selenium 3.0. If you’ve been waiting for a stable release since 2.53.1, now’s your chance to update. And if you do, here is what you’ll find:

As we’ve said before, for users of the WebDriver APIs this is a drop-in replacement. You’ll find that modern browsers, such as Chrome and Edge will continue to work just as before, and we’ve taken the opportunity to fix some bugs and improve stability. Selenium Grid users may require updates to their configuration as the json config file format has been updated, as have some of command line parameter options, but the upgrade should also be smooth.

Selenium 3 is Coming

Tue, 04 Oct 2016 00:00:00 +0000

Selenium 3 is coming! As I write this, we think that “beta 4” will be the last beta before the official 3.0 release. I’m here to tell you about what’s changed, and what impact this will have on your testing.

TL;DR:

WebDriver users will just find bug fixes and a drop-in replacement for 2.x.
Selenium Grid users will also find bug fixes and a simple update.
The WebDriver APIs are now the only APIs actively supported by the Selenium project.
The Selenium RC APIs have been moved to a “legacy” package.
The original code powering Selenium RC has been replaced with something backed by WebDriver, which is also contained in the “legacy” package.
By a quirk of timing, Mozilla have made changes to Firefox that mean that from Firefox 48 you must use their geckodriver to use that browser, regardless of whether you’re using Selenium 2 or 3.

In more depth:

When we released Selenium 2.0 in 2011, we introduced the new WebDriver APIs, and encouraged everyone to start moving to them. If you’re using the WebDriver APIs, then Selenium 3.0 is a simple drop-in upgrade. We’ve not changed any of the public WebDriver APIs, and the code is essentially the same as the last 2.x release. If you’re using Selenium Grid, the same applies: in most cases, you can just drop in the new JAR (or update your maven dependency to 3.0.0), and you’re done.

Announcing Selenium 3.0-beta1

Fri, 29 Jul 2016 00:00:00 +0000

At SeleniumConf in 2013, we announced that a new major version of Selenium would be released “by Christmas”. Fortunately, we never said which Christmas, as it has taken us a while to make all the changes we wanted to make! We’re excited to announce the release of the first beta — Selenium 3.0.0-beta1.

We’d love you to try it out on your projects, and provide us with feedback on where the rough edges are before we ship the 3.0 itself! Please remember that this is a beta release, so your feedback is incredibly helpful and valuable in order to help us smooth any rough edges.

Announcing Selenium 2.26: the “It’s Really Real” Release

Fri, 02 Nov 2012 00:00:00 +0000

It’s been a long time since we announced a new Selenium release on this blog, as we moved to a model of quicker releases, but we’ve been working on 2.26 for far longer than normal — it’s out! Download it now! — so I thought it best to let you know. We’re aiming to head back to faster releases, so hopefully you won’t see another blog post about the release for a while (though I’m sure they’ll appear in the “Smatterings of Selenium” posts)

Announcing Selenium 2.22

Tue, 29 May 2012 00:00:00 +0000

It’s been a while since the last Selenium release, but I’m happy to announce that Selenium 2.22 is now available for download. This is a big release for us and features two major changes.

The first is that Selenium 2.22 is the first version that requires Java 6 in order to run. This has been the case for the Selenium Server for some time, but this is the first time the client code has required Java 6. Since Java 5 was “end of lifed” in 2009, we don’t expect this to impact many users.

Announcing Selenium 2.19: the Prancing Unicorn release

Wed, 08 Feb 2012 00:00:00 +0000

You might be pleased to hear that Selenium 2.19 has been released (download it from here!). There’s one big user facing changing that we’d like to tell you about: the webdriver-backed selenium can now be used in supported languages.

By providing this capability, it’s possible to migrate from RC to the WebDriver APIs without rewriting all your tests in one fell swoop (which must be a Good Thing, right?) An example of how to use it in Python would be:

Selenium 2.16 Released: Welcome to 2012!

Thu, 05 Jan 2012 00:00:00 +0000

It’s been a while since we last blogged about a Selenium release. Since the release of 2.0, we’ve been attempting to give you a fresh and shiny Selenium release every week (though, in reality, we’re managing to get you one every 10 days on average). This allows you to pick the version that’s most suitable for you and your teams, but provides a route for quick feedback on how we’re doing. I think we’ve now ironed out a lot of the initial problems and bumps we ran into, so we are extremely proud to announce the release of Selenium 2.16.

Selenium 2.9 Released

Thu, 20 Oct 2011 00:00:00 +0000

We’re pleased to announce the release of Selenium 2.9. As well as improving the stability of Grid under high loads, we’ve added an experimental (and temporary!) feature that allows the Firefox driver to use a different mechanism for determining when a page is loaded. This is designed to handle the case where the driver appears to hang, as it’s waiting for all incoming requests to complete before continuing. How to enable this mode is listed in the changelog.

Selenium 2.8 Released

Thu, 06 Oct 2011 00:00:00 +0000

In keeping with our (roughly) weekly releases, Selenium 2.8 was released today (and on Maven too), with a *huge* list of bug-fixes! As well as improved stability, if you’re using the Java API, this release adds the ability to upload files to a RemoteWebDriver server (see RemoteWebDriver.setFileDetector (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/remote/RemoteWebDriver.html#setFileDetector(org.openqa.selenium.remote.FileDetector))).

Particular thanks have to go out to our two newest committers, Alexei Barancev and Ajay Kemparaj, for the copious bug-fixes they’ve contributed!

We’re already hard at work getting 2.9 ready for next week with even more more bug-fixes – watch this space!

Selenium 2.6 Released

Fri, 16 Sep 2011 00:00:00 +0000

If you’ve been watching this blog carefully you’ll have noticed that the last release announcement we made was for 2.3, so it may come as a surprise that we’re announcing that 2.6 has been released (even on Maven!). Don’t worry: 2.4 and 2.5 were released on time and without muss or fuss. 2.6, on the other hand has been almost three weeks brewing.

Selenium 2.6 introduces a raft of improvements and stability fixes. Kristian Rosenvold has been working wonders on Grid 2.0, addressing many reported issues and cleaning up the implementation. In the finest tradition of the project, I now owe him a dinner for his hard work. Thank you, Kristian!

Selenium 2.3 Released

Tue, 02 Aug 2011 00:00:00 +0000

Continuing our new tradition of weekly releases, we’re very pleased to announce the release of Selenium 2.3. The release notes for this version are pretty slim:

Better detection of clickable areas in Firefox.
Merge of Google-contributed code into the underlying javascript libraries used by the drivers.

We’ve also fixed bugs, one of which was being a nuisance for users of IBM’s JRE. The complete changelog can be found in the zipped downloads or in our source tree (http://selenium.googlecode.com/svn/trunk/java/CHANGELOG).

Selenium 2.2 Released

Tue, 26 Jul 2011 00:00:00 +0000

The feedback from the last release was heard loud and clear: little and often it is!

We’re proud to announce the release of Selenium 2.2. What’s new this time? For many users, this is simply a bug fix release as there are no new major features. One thing you might appreciate is better exceptions (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/IllegalLocatorException.html) being thrown when xpath searches return something other than a web element when using the WebDriver APIs, and we’re continuing to tweak the emulation of user events.

Selenium 2.1 Released

Mon, 18 Jul 2011 00:00:00 +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.

Selenium 2.0: Out Now!

Fri, 08 Jul 2011 00:00:00 +0000

We are very, very pleased to announce the release of Selenium 2.0. If you’ve been waiting for a stable release since 1.0.3, now’s the chance to update. And if you do, what will you find?

For users of Selenium 1, this is a drop-in replacement. You’ll find support for modern browsers such as Firefox 5 and IE 9, as well as a wealth of bug fixes and stability improvements. That’s one reason to update, but what other reasons are there?

New ChromeDriver

Thu, 07 Jul 2011 00:00:00 +0000

The ChromeDriver is composed of two major pieces. There are the client APIs, which you use in your tests, and there’s a server part, which the client APIs know how to start and run and which takes the form of an executable called “chromedriver”. The server piece is maintained by the Chromium team, and they’ve just released a new version, with support for Chrome 14 and with bug fixes. If you’re using Selenium 2.0rc3 and you’re also using the ChromeDriver, head over to the Chromium project’s download page for the latest and greatest!

Selenium IDE 1.0.12 – now with Firefox 5 support

Mon, 04 Jul 2011 00:00:00 +0000

Last week we quietly released Selenium IDE 1.0.12 on the website. It has Firefox 5 support along with other improvements. See the release notes and unofficial announcement. Download it here or ask Firefox to check for plugins updates.

And for those who did not download 1.0.11 (it was not pushed through the update system) you will want to read about the formatter change that landed.

Selenium 2.0rc3: The “Next One’s The Big One” Release

Mon, 27 Jun 2011 00:00:00 +0000

When we pushed the 2.0rc1 live, we really hoped that the next release would be 2.0 final. We very quickly got some feedback that encouraged us to push a 2.0rc2. Now, after just under three weeks, we’re launching a third and final release candidate. You can download it from the Selenium HQ site or directly from Google Code.

We think we’ve addressed many of the common issues, added some polish and added a host of bug fixes and minor changes, and we hope to hear your feedback! The following headline changes have been made in Selenium 2rc3:

Selenium 2.0rc2: The Better Working Release

Thu, 02 Jun 2011 00:00:00 +0000

You win some and you lose some. We’d been really pleased to get Selenium 2.0rc1 out, so we were pretty disappointed to hear that some of you were running into problems with the Java version of the IE driver not launching IE sometimes. That’s definitely not good, so we fixed the problems and have released Selenium 2.0rc2. It’s the same as rc1, but with fewer problems 🙂

We’re still very keen to hear your feedback! Let us know what you think!

Selenium 2.0rc1: The Grid Release

Wed, 01 Jun 2011 00:00:00 +0000

We’re very happy to announce the first Release Candidate for Selenium 2, available for Java, C#, Ruby and Python. The API has been stabilised and the functionality needed for the final 2.0 release is mostly in. We’re going to be working hard to get there as soon as possible, but now’s the perfect time to test the waters and provide us with any feedback you may have! Grab the downloads from the site!

Selenium IDE 1.0.11 – Now with Firefox 4 Support!

Mon, 30 May 2011 00:00:00 +0000

We know that you have been waiting eagerly for this release and you have to wait no more. Selenium IDE 1.0.11 is now here and you can get it from the seleniumhq download site. The update will also be pushed to you automatically over the next couple days.

Other things of note around this release
•Release Notes
•Where to log bugs
•Welcome Selenium IDE 1.0.11 (with Firefox 4 support)

Selenium 2.0b3: The Next Gen Browser Release

Mon, 21 Mar 2011 00:00:00 +0000

It’s been about 5 weeks since the release of beta 2, so we’re very pleased to announce that Selenium 2.0b3 has just been released simultaneously for Java, .Net, Ruby and Python. You can download it from Selenium HQ or from the Google Code site. This release focused on providing excellent support for the next generation of browsers, particularly IE 9 and Firefox 4, and we think you’ll like what you’ll find.

Restructured documentation at Selenium HQ
An improved user interaction API
- Including experimental IME support on Windows.
Alerts and prompts handling for IE.
Marked the following APIs as obsolete in .Net:
- IRenderedWebElement.Hover()
- IOptions.Speed
Even more improvements to the Java webdriver-backed selenium
- We’ll document the migration path before 2.0b4 is out!
A significantly faster Android Driver (http://selenium.googlecode.com/files/android-server-2.0b3.apk)

As well as these changes, there’s also the regular clutch of bug fixes and tweaks. For the number crunchers, there were a total of 331 changes that landed in the 5 weeks since the last release, with the 5 most active contributors working on each of the different languages supported by Selenium.

Selenium 2.0b2 Released

Tue, 15 Feb 2011 00:00:00 +0000

We’ve just released Selenium 2.0b2. If you’re the impatient sort who loves to have the latest and greatest, head over to the download site and get it while it’s hot. If you’re a Python user, then all you need to do is a simple “pip install -U selenium”. Ruby users can, as ever, simply run “gem install selenium-webdriver”. Maven users need to wait just a little bit longer: we’re going to be checking the release in ASAP.

OperaDriver Released

Wed, 09 Feb 2011 00:00:00 +0000

I think the word that I’m looking for is “wow”. Perhaps “Wow!” would express the concept a little more clearly. Perhaps “WOW!” would be even clearer. Yes, definitely. “WOW!” is a good way of describing this.

Before Christmas, Opera Software announced a pre-release of OperaWatir, an implementation of the Watir 2 API. What you may not know is that Watir 2 rests on the same WebDriver core as Selenium 2. Today, Opera made the source of the OperaDriver available on github: https://github.com/operasoftware/operadriver

Selenium 2.0 beta 1 Release

Fri, 24 Dec 2010 00:00:00 +0000

We recently released the first of the betas for Selenium 2. It’s available for Java, C# and Ruby. If you’ve been holding off trying Selenium 2 because of the alpha label, then the biggest improvement you’ll see is with the new WebDriver APIs, but there’s a lot more!

A promise of relatively stable APIs
For Firefox only right now, an API for dealing with alerts, prompts and confirms (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/WebDriver.TargetLocator.html#alert()).
A brand new IE driver.
Better selenium emulation (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/WebDriverBackedSelenium.html) when using webdriver
And a better implementation of webdriver’s API backed by the traditional Selenium technology (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/SeleneseCommandExecutor.html).
Ubiquitous use of Sizzle for emulating CSS selectors where native CSS selectors aren’t supported
The advanced user interactions (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/interactions/package-frame.html) API
An update to the AndroidDriver’s Android app.

Of course, we’d love this release to be completely bug free, but this is, after all, a beta, so there are some known issues:

Selenium 2.0a6 Released

Fri, 08 Oct 2010 00:00:00 +0000

We are extremely pleased to announce the release of Selenium 2.0a6! Head over to the downloads page to get it while it’s hot, or wait just a little bit longer for it to appear in a maven repo near you. The .Net version will also be updated soon too, and the python and ruby libraries have been having smaller, more frequent releases all this time.

You’ll be pleased to hear that the Selenium 1.0 APIs have remained constant, so what’s changed? Here, in no particular order are the major changes you’ll find in 2.0a6:

Selenium 2.0a5 Released

Wed, 14 Jul 2010 00:00:00 +0000

I’m pleased to announce the release of Selenium 2.0a5, available for immediate download. This release brings a host of changes under the hood, and represents the efforts of many contributors. Highlights include:

New interfaces (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/html5/package-frame.html) for dealing with HTML 5 elements.
An API for implicit waits (http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/WebDriver.Timeouts.html): quietly waiting until an element is present before continuing with a test. You can use them like this: driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS)
A revamped Firefox driver.
More shared code between Selenium and WebDriver.
You can now pass firefox profiles to the remote webdriver (this includes extensions and proxy settings!)
Improved .Net bindings: lots of updates to help bring them more in-line with the Java equivalents.

Waiting in the wings for release soon is an AndroidDriver, which opens up the world of testing webapps on Android devices through the Selenium WebDriver API.

Selenium IDE – Looking back and looking forward

Fri, 09 Jul 2010 00:00:00 +0000

Its been around six months and three releases since I took the reins of Selenium-IDE. The fundamental change in that time has been the adoption of a plugin model like the fine folks over that Firebug. (We’re also self-hosting it which is big from a project internals perspective.)

Right now, you can add custom user-extensions and formatters, but in the very near future you will be able to add location strategies as well.

Selenium Grid 1.0.8 Released

Thu, 10 Jun 2010 00:00:00 +0000

We’re pleased to announce the release of Selenium Grid 1.0.8. This release fixes multithreaded issues with the Selenium Grid hub that appeared randomly under heavy load. If you’ve ever seen a log message about HttpClient being accessed by multiple threads, you definitely want to upgrade. Even if you haven’t, this release is highly recommended for all.

You can download it now or view the changelog. The list of changes is:

Multi-threaded issue with access to HttpClient has been resolved, fixing random crashes on a heavily loaded grids

Many thanks go out to Chris Gulley for identifying and fixing the problem. As always, patches and bug reports are appreciated:

Selenium IDE 1.0.7 – Now with Drag-and-Drop!

Thu, 27 May 2010 00:00:00 +0000

So its a month later than planned, but Selenium IDE 1.0.7 is now available. The delay was due to some internal build changes and not code, but one of the code changes that is there more than makes up for the delay.

That’s right, drag-and-drop has finally arrived to Se-IDE — though credit lies with Jérémy Hérault for implementing it.

Oh, and if you are Swedish, there is now a localization for you. Yes, a real one. Not just one that makes everything say Bork as was suggested to me. Although a Pirate locale might be arrr-some.

Selenium Grid 1.0.7 Released

Tue, 11 May 2010 00:00:00 +0000

Following up on the Selenium Grid 1.0.6 release, which was mostly a bug fix release, we’re pleased to announce the release of Selenium Grid 1.0.7. This is another bug fix release that focuses primarily on how Selenium Grid handles browser sessions.

You can download it now or view the changelog. The list of changes are:

Hub now instructs remote controls to shutdown a session if the hub is going to remove it due to being idle for too long
Added ability to specify timeout period when waiting for remote controls to become available. Now the client can timeout gracefully and decide what it would like to do next
Handle common case of session ID not being found, either because it timed out or was already closed; rather than raising a NullPointerException we now raise a NoSuchSessionException
Truncate long command response bodies to 128 characters
Retry remote control checks up to three times before deciding that a remote control is unreliable or unresponsive. This prevents aggressive unregistration of hosts that are busy or suffer from network issues

As always, patches and bug reports are appreciated:

Selenium 2.0a3 Released

Mon, 19 Apr 2010 00:00:00 +0000

Selenium 2.0a3 has been released and can be downloaded from the Selenium project site. This is a major update to 2.0 and all users are encouraged to update. The new features include:

An improved remote protocol.
Updating the version of HtmlUnit used to 2.7.
Improved support for simulating user interactions with the browser via native events on Linux.
Better support for Firefox 3.6.
Bug fixes

The .Net, Python and Ruby bindings will be updated soon, as will the maven artefacts.

Selenium Grid 1.0.6 Released

Tue, 13 Apr 2010 00:00:00 +0000

Following up on the Selenium Grid 1.0.5 release, which added self-healing features to ease grid management, we’re pleased to announce the release of Selenium Grid 1.0.6. This is a bug fix release for 1.0.5 with some minor new additions.

You can download it now or view the changelog. The summary of changes are:

Fixed some concurrent modification issues that may have resulted in NullPointerExceptions
Fixed issue with shutting down workers with Rakefile
Added PID file support for hub and worker started via Rakefile, making it easier to use a process monitor such as monit

In case you missed the announcement, Philippe is no longer maintaining Selenium Grid. We thank him for his years of effort and helping the project get to where it is today. This is my first release as the new Selenium Grid maintainer. I will be getting out a new post shortly that lays out the future for the project [UPDATE: The promised post is live]. In the meanwhile, please note the new location of several key resources:

Selenium 1.0.3 Released

Wed, 24 Feb 2010 00:00:00 +0000

Hot off the heals of 1.0.2, we’re releasing Selenium Remote Control 1.0.3. You can download it now (http://selenium.googlecode.com/files/selenium-remote-control-1.0.3.zip).

There is no functional difference between this version and 1.0.2, other than it is packaged up a little nicer and we’ve clarified the relationship between selenium-server and the client drivers. That is: we are not releasing new client drivers with future 1.x releases. The reason is that we locked down the API in version 1.0.1 and so there is no need to push out the same code each time. As such, when you download 1.0.3, you’ll see all the client drivers are labeled version 1.0.1, which is expected.

Selenium 1.0.2 Released: Firefox 3.6 and Snow Leopard Support

Tue, 23 Feb 2010 00:00:00 +0000

Today we’re happy to announce that Selenium Remote Control 1.0.2 has been released. While most of our efforts are on Selenium 2.0, we understand that there are millions of Selenium users that still need the 1.x line supported. That’s why we’ve said from the start that our goal is make 2.x 100% backwards compatible with 1.x. And that’s why we’re releasing a new version of Selenium RC today.

Download it here (http://selenium.googlecode.com/files/selenium-remote-control-1.0.2.zip).
