Browser Support Policy

We support the latest stable releases of all major browsers and platforms. Beta, alpha, and release candidate versions are not actively supported. The support list is driven by trends in browser usage and updates from software developers — if a vendor no longer supports a version, Euclid will not either.

Your site is built using the latest stable browser versions available at the time of launch. We will continue to support those versions. However, browser vendors may make changes we cannot predict. As a result, we cannot guarantee your site will remain fully functional in all future versions. Billable time may be required to update your site if newer browsers introduce changes that disrupt existing functionality.
