 - [Multiple inputs](https://github.com/gchq/CyberChef/wiki/Multiple-Inputs) are now supported in the main web UI, allowing you to upload and process multiple files at once [@j433866] | [#566]
 - A [Node.js API](https://github.com/gchq/CyberChef/wiki/Node-API) has been implemented, meaning that CyberChef can now be used as a library, either to provide specific operations, or an entire baking environment [@d98762625] | [#291]

+# Security Policy
+
+## Supported Versions
+
+CyberChef is supported on a best endeavours basis. Patches will be applied to
+the latest version rather than retroactively to older versions. To ensure you
+are using the most secure version of CyberChef, please make sure you have the
+[latest release](https://github.com/gchq/CyberChef/releases/latest). The
+official [live demo](https://gchq.github.io/CyberChef/) is always up to date.
+
+## Reporting a Vulnerability
+
+In most scenarios, the most appropriate way to report a vulnerability is to
+[raise a new issue](https://github.com/gchq/CyberChef/issues/new/choose)
+describing the problem in as much detail as possible, ideally with examples.
+This will obviously be public. If you feel that the vulnerability is
+significant enough to warrant a private disclosure, please email
+[oss@gchq.gov.uk](mailto:oss@gchq.gov.uk) and
+[n1474335@gmail.com](mailto:n1474335@gmail.com).
+
+Disclosures of vulnerabilities in CyberChef are always welcomed. Whilst we aim
+to write clean and secure code free from bugs, we recognise that this is an open
+source project written by analysts in their spare time, relying on dozens of
+open source libraries that are modified and updated on a regular basis. We hope
+that the community will continue to support us as we endeavour to maintain and
+develop this tool together.
