I have a couple of points:

• Since we don't have some integration or end-to-end or ui tests, do we run a smoke test even manually for the changes?
• generally speaking, this kind of upgrade should be carried out gradually بالتدريج as in bigger apps upgrading everything at once can introduce some unintentional issues (either due to compatibility issues or even some breaking changes). I understand that this not a huge app, but I thought to share my thoughts to raise awareness. :))
