We've added several features to the Svix service, including configurable rate-limiting for webhooks, a new Svix CLI listen command that provides a public-facing URL for webhook development, a webhooks debugger and playground tool called Svix Play, a C# library for signing and verifying webhooks, support for multiple environments under the same account, managing organization members, and adding webhook notifications from Svix to user dashboards. Additionally, we've made general improvements to our backend, dispatcher, and UI, laying the groundwork for future exciting features.
