以下是rails 3.1.0 app和rails 3.2.0 app的带注释的递归diff，不包括Gemfile.lock和config/initializers/secret_token.rb。
.gitignore - 添加了主要斜杠（取决于您的应用，这可能会导致您在运行git status时出现一些先前被忽略的文件 - 您可能想要添加它们在）
diff --recursive rails-3.1.0/depot/.gitignore rails-3.2.0/depot/.gitignore

> # See http://help.github.com/ignore-files/ for more about ignoring files.

> # If you find yourself ignoring temporary files generated by your text editor
> # or operating system, you probably want to add a global ignore instead:
> # git config --global core.excludesfile ~/.gitignore_global
>
> # Ignore bundler config
> /.bundle
>
> # Ignore the default SQLite database.
> /db/*.sqlite3
>
> # Ignore all logfiles and tempfiles.
