+Fix issue with `isbot` v4 released on 1/1/2024
+
+* `remix dev` wil now add `"isbot": "^4"` to `package.json` instead of using `latest`
+* Update built-in `entry.server` files to work with both `isbot@3` and `isbot@4` for backwards-compatibility with Remix apps that have pinned `isbot` to v3
+* Templates are updated to use `isbot@4` moving forward via `create-remix`
