- If you upgrade a project &quot;just because&quot; then you&#x27;re doing it wrong. That isn&#x27;t the fault of  the rails team.
- New versions don&#x27;t break that many things that aren&#x27;t tied directly to how rails works. Most general gems will work just fine, and a lot of tutorials from 3.2 are still more or less usable with minimal googling. Generators work the same, active record&#x27;s api hasn&#x27;t changed much, action view works the same way.<p>And don&#x27;t get me started on the mess that a node dependency graph can become.
