It's also a safer choice as it prevents package collisions.\n- Non-isolated environment (used to be the default choice) might start a bit faster, but can lead to issues mentioned above. It will also become a subject to deprecation in the future.\n- We recommmend you **update the code regularly** to make sure it runs with the latest versions of all packages. This will help you avoid issues with abandoned packages and **security vulnerabilities**.",
