“Selenium 107” is not established as a Selenium project version. The likely reference is to Chrome DevTools Protocol (CDP) version 107 files added in the Selenium JavaScript binding’s v4.6.0 changelog. That historical entry is a compatibility-related change, not a guarantee that every Selenium release or Chrome installation supports every CDP feature. Selenium continues to release across its language bindings and Grid; use the current official listing for the binding you need.
What is Selenium 107?
The official source that best explains the “107” wording is the Selenium JavaScript changelog. Its v4.6.0 section says CDP files for v107 were added and files for v104 removed. In context, 107 refers to a Chrome DevTools Protocol version in the JavaScript binding’s release notes—not to a Selenium project release called Selenium 107.

The changelog does not provide a universal Chrome compatibility matrix or promise that every CDP command works with every browser, driver, or Selenium binding. Treat the note narrowly: it records a change to versioned CDP files in that JavaScript release.
What changed in Selenium 4.6.0?
The following items are from the JavaScript binding’s v4.6.0 changelog; they should not be read as a complete account of every language binding’s release.
#1 Best Overall
- CDP files: files for v107 were added and those for v104 removed.
- Selenium Manager: support was added.
- Grid session search: the Grid interface gained a search field for running sessions.
- Grid keyboard interaction: Enter could be used to confirm.
- JavaScript fixes: the notes list a thenable fix for
isPromise()and a fix making methods static.
The changelog records these as release notes; it does not establish a release date, browser-support guarantee, or identical changes in other bindings.
Does Selenium support Chrome 107?
The v4.6.0 JavaScript note is evidence that its package included CDP files for v107. It is not enough on its own to answer whether a particular Selenium setup supports a particular Chrome 107 workflow. Compatibility depends on the binding and Selenium version in use, the browser and driver versions, and whether the feature you need is available through that combination.
For a practical check, compare the exact Selenium release and language binding with the browser or CDP version involved, then confirm that the desired feature appears in that binding’s release notes. This is a way to investigate a setup, not a substitute for an official compatibility matrix.

- Open the official Selenium downloads page.
- Find the language binding you use. Selenium describes these client drivers as tools for scripts that interact with Selenium Server (Remote WebDriver) or create local WebDriver scripts, and identifies the listed bindings as the core ones supported by the main project.
- Use the version shown for that binding rather than assuming that a historical JavaScript changelog entry applies to it.
- For release context, read the corresponding announcement and binding-specific change notes before upgrading.
In the official listing dated September 9, 2026, .NET/C# stable was shown as 4.49.0. Selenium’s announcement on that date named JavaScript, Ruby, Python, .NET, Java, and Grid. Those dated details illustrate that Selenium releases cover multiple parts of the project; they are not a promise that every binding has the same version number or release contents.
How the 4.6.0 note fits newer Selenium releases
The Selenium 4.49 announcement, dated September 9, 2026, highlights newer BiDi work and a Grid fix for file downloads when a filename contains spaces. This shows that current release notes address several bindings and Grid, and that protocol-related work is not limited to the historical CDP v107 entry. The cited announcement does not say that BiDi replaces all CDP use.
