Hey Diego, great talk, didn't know about the dry-run, looking forward to trying it out!
Good overview of a lot of different programming practices. Great code examples
Good content, but spent a fair amount of time talking about why schema migrations are good, vs. going into more detail about interesting stuff Doctrine's migrations offers, IMO.
Good job on the talk. Clear examples and a lot of good tips about firsthand experiences of managing a codebase and database schema
