+### Preventing out-of-date prebuilds being used
+
+By default, if the latest prebuild workflow has failed, then a previous prebuild for the same combination of repository, branch, and `devcontainer.json` configuration file will be used to create new codespaces. This behavior is called prebuild optimization.
+
+We recommend keeping prebuild optimization enabled, because it helps ensure that codespaces can still be created quickly if an up-to-date prebuild is not available. However, as a repository administrator, you can disable prebuild optimization if you run into problems with prebuilt codespaces being behind the current state of the branch. If you disable prebuild optimization, codespaces for the relevant combination of repository, branch, and `devcontainer.json` file will be created without a prebuild if the latest prebuild workflow has failed or is currently running.
