In addition to new components and big features, new Symfony versions usually add "quality of life" features. These are little features that make you more productive and improve your developer experience in general.

The dump() and dd() helpers provided by the VarDumper component are a lightweight alternative when you don't need full-featured debuggers like Xdebug. However, these helpers behave differently in the browser and the command console.

In the browser, dump() and dd() display both the dumped contents and the file path and line number where they were called. However, in the console you only see the dumped contents, so you don't know where the helper was called:

In Symfony versions prior to 4.4, dumps in the console didn't show their location

Starting from Symfony 4.4, you'll see a ^ character next to the dumped contents. Click on it to go directly to the file and line where the dump was generated:

In Symfony 4.4, console dumps show a clickable marker which points to the location where the dump was generated
