We support the latest, stable releases of all major browsers and platforms. We do not actively support beta, alpha, or release candidate versions of browser software. The support list is driven by trends in browser usage and updates from software developers — if they no longer support 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 that we cannot predict. As a result, we cannot guarantee that your site will remain fully functional in future versions. Billable time may be required to update your site if newer browsers introduce features that disrupt existing functionality.
