# Why Are Regular Chromium Upgrades Needed? Regular Chromium upgrades are needed in order for our synthetic tests to accurately mimic the true browser experience of a user, because most organizations actively ensure that the browsers on users' laptops and desktops are up to date. In the past, both ThousandEyes and our customers have been negatively impacted by a few conditions within the Chromium open source project: * Chromium updates are not backwards compatible with one another. In our case, this meant that transaction test scripts that worked on a previous version of Chromium might need re-working to run on a later version of Chromium. * Updates from the Chromium open source project are not always announced ahead of time so there’s less forward visibility for teams that rely on Chromium within their own toolsets. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.thousandeyes.com/product-documentation/browser-synthetics/dual-chromium-option/why-chromium-upgrades.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
