Selenium 3.0.0-beta1 was a preview release announced on July 29, 2016—not a current setup recommendation. Its main change was replacing Selenium’s original RC implementation with one backed by WebDriver. Most WebDriver users were expected to upgrade with little change; Java users who still needed the legacy RC APIs had to add the separate leg-rc package. To reproduce the beta, use its archived packages and release-era requirements in an isolated environment; for new work, follow Selenium’s current documentation.
What changed in Selenium 3 Beta 1?
The beta was announced by Selenium project author Simon Stewart on July 29, 2016, as a release for users to try and provide feedback on. The headline was an internal implementation change, not a sweeping redesign of the public WebDriver API.

The RC implementation moved behind WebDriver
Selenium removed its original Selenium Core implementation, which supported the older Remote Control (RC) APIs, and replaced it with an implementation built on WebDriver. The project had already been encouraging users to move from RC to WebDriver. For typical WebDriver API users, Selenium 3 was expected to be a drop-in upgrade from Selenium 2.x.
RC users were more likely to encounter compatibility issues because the implementation beneath those APIs had changed. Java users who still needed the old RC APIs were directed to add the separate leg-rc package rather than assume those APIs were still in the main Java package.

Other beta-era Java changes
The beta’s Java changelog also recorded a remote WebDriver protocol handshake that logged whether the wire dialect was OSS or W3C, and the use of different codecs rather than command names ending in *w3c. For W3C remote ends, getAttribute and isDisplayed handling used atoms. The release also introduced an HTML table runner backed by WebDriver, downloadable as selenium-html-runner.jar.
Who was likely to need migration work?
| Existing code | Expected continuity in the beta-era guidance | What to check |
|---|---|---|
| WebDriver APIs | Described as generally a drop-in upgrade from Selenium 2.x. | Check your language binding, browser driver, and any Grid configuration or command-line options. |
| Legacy RC APIs | More likely to encounter compatibility issues after the implementation change. | Java users needing RC APIs had to add leg-rc; migrate to WebDriver where practical. |
| Selenium Grid | The October 4, 2016 migration guidance said it generally needed only a new JAR or Maven dependency. | Some Grid configuration and command-line options had changed, so verify those rather than treating every setup as identical. |
What Java and browser requirements applied in 2016?
These are requirements stated for the 2016 beta, not current browser setup instructions. Java components required Java 8. The release announcement described the following browser arrangements:
Rank #2
- Firefox: use Mozilla’s geckodriver. Firefox 48 required geckodriver because of changes in Firefox itself; this applied even when using Selenium 2.
- Safari: use Apple’s safaridriver on macOS Sierra or later.
- Microsoft Edge: use Microsoft’s WebDriver server.
- Internet Explorer: official support began with IE 9.
Driver and browser compatibility is particularly time-sensitive for a beta from 2016. Do not treat this list as instructions for configuring a modern browser; use current Selenium documentation for a new project.

The official Selenium downloads archive lists beta 1 packages for Java, .NET, and the server. Its listed artifacts include selenium-java-3.0.0-beta1.zip, selenium-dotnet-3.0.0-beta1.zip, selenium-dotnet-strongnamed-3.0.0-beta1.zip, selenium-server-3.0.0-beta1.zip, and selenium-server-standalone-3.0.0-beta1.jar. The archive gives the release date as July 29, 2016.
- Keep the trial separate. Use an isolated project or environment, rather than replacing dependencies in a current production setup.
- Use the beta version string. In a Java Maven project, the version was
3.0.0-beta1. A minimal dependency declaration is:<dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.0.0-beta1</version> </dependency> - Use Java 8 for Java components. If the project still relies on Selenium RC APIs, add the release-era
leg-rcpackage as directed in the beta announcement. Prefer WebDriver for a new experiment. - Download the matching browser driver separately where needed. Follow the beta-era browser arrangements above only when reproducing the historical setup; browser and driver compatibility may make a present-day trial impractical.
- For a standalone server trial, use the archived
selenium-server-standalone-3.0.0-beta1.jarartifact. The archive also lists the server ZIP package. - For new automation, use the current Selenium downloads page and documentation rather than this archived beta.
Or skip the browser setup
If the goal is simply to capture a web page as an image or PDF, rather than to reproduce Selenium 3 Beta 1, ScreenshotNeo is a screenshot API and MCP server for developers. One GET request can return a PNG, JPEG, WebP, or PDF. Its API accepts cookie banners before capture and removes known consent platforms, newsletter popups, and chat widgets; each step can be turned off.
For example, this cURL request captures a page as WebP (replace the example URL or API key as needed):
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo documentation for request options. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed as clean shots; response headers identify the page verdict and billing status. An MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents and MCP clients. The free plan includes 1,000 shots per month with no card; paid plans start at $5 for 3,000 shots.

Selenium 3.0.0-beta1 is useful as a historical release to reproduce or evaluate, not as a stable choice for a new project. The stable Selenium 3.0 release followed on October 13, 2016, and the official downloads page now describes a much newer release line. For present-day installation, choose the current Selenium documentation; use the archive only when the beta itself is the subject of your work.
Frequently Asked Questions
Was Selenium 3.0.0-beta1 a stable production release?
No. It was explicitly announced as a beta for users to try and report feedback on.
Can I use the beta artifacts for a current browser automation project?
The artifacts remain listed in the official archive, but that does not establish compatibility with present-day browsers or drivers. For a new project, follow current Selenium documentation.
