  1. If your list is based on a content type - upgrading solution with the new CT definition could solve the issue simply upon Update
  2. If your list has columns directly added, of course adding a column programatically, again via the same Upgrade feature.

Bottom line, you should plan really upgrade cycles to handle minor/major releases, while considering solution breakers, particularly when changing schema frequently. Rather plan base-content types and derive children so you could support more flexibility.

And in conjunction with content type hubs, if you don't create features to upgrade the definitions, you can add the fields through the UI and update the entire farm. – Eric Alexander May 10 '13 at 16:45
