+## Support statement
+
+New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Older releases will no longer be supported when they reach [end-of-life](https://docs.newrelic.com/docs/browser/browser-monitoring/getting-started/browser-agent-eol-policy/). Release dates are reflective of the original publish date of the agent version.
+
+New browser agent releases are rolled out to customers in small stages over a period of time. Because of this, the date the release becomes accessible to your account may not match the original publish date. Please see this [status dashboard](https://newrelic.github.io/newrelic-browser-agent-release/) for more information.
+
+Consistent with our [browser support policy](https://docs.newrelic.com/docs/browser/new-relic-browser/getting-started/compatibility-requirements-browser-monitoring/#browser-types), v1.256.1 of the Browser agent was built for and tested against these browsers and version ranges: Chrome 114-123, Edge 114-123, Safari 16-17, and Firefox 115-124. For mobile devices, v1.251.1 was built and tested for Android Chrome 100-123 and iOS Safari 15.5-16.2.
