Follow the below steps to change your project's Composer version.
The next bundle you create will be built using the new version of Composer. It's worth noting that existing bundles will still use the version of Composer they were originally built with.
Changing the default version
Navigate to your project's Build & Deploy page.
Under the "Composer Version" section, select the version of Composer you want to use going forward from the dropdown.
Click the "Save" button.
Changing via the Servd YAML file
You can also control the Composer version by setting it in `servd.yaml` in the root of the project's repository. This will override the default version defined in the Servd dashboard. Visit our Servd YAML file documentation page to learn more.
