# Breaking Changes ## Introduction Gum attempts to be fully backwards compatible - all old projects should continue to work in new versions of Gum. Unfortunately at times, some changes are made to the Gum tool which may break old project functionality, or which may require projects to be modified by Gum. Most of the time these changes happen automatically as a project is loaded by Gum, requiring no manual changes. However, if your project is loading Gum files and interacting with them in your code, these changes may require updates to your project. This section outlines the breaking changes and provides instructions on how to adjust to these changes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.flatredball.com/gum/gum-tool/upgrading/breaking-changes.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
