New Major Serverless Toolkit Version

The Serverless Toolkit, a collection of open-source CLI tooling for Twilio Functions and Assets, has released its first major version bump since 2019. The new version includes various bug fixes, new features, and some breaking changes. A key feature is improved configuration support through the introduction of a new `.twilioserverlessrc` file, which allows users to alter out-of-the-box behavior and supports multiple Twilio projects, environments, or commands. Another significant change is the removal of the `.twilio-functions` file, replaced by two new files: `.twilioserverlessrc` for configuration needs and `.twiliodeployinfo` for deployment-related functionality. Additionally, the toolkit now has better support for credentials from the Twilio CLI, improved compatibility with machine-readable output, and a brand-new Assets plugin that allows hosting public static files on Twilio Assets. The release also includes new guides and breaking changes, such as isolated local function execution and the removal of Node.js 10 support.
