What does adding or removing the question mark in sentences ending with ね
change about the meaning, if anything?

> 暑いですね
>
> 暑いですね？

> 去年もそのシャツ着てたよね
>
> 去年もそのシャツ着てたよね？




If you inflect your voice, you are generally seeking support/approval or
outright asking a question in a casual way.

A response to seeking support would not be inflected.

> A: 暑いですね？  
>  B: ですね。

*note: the response would usually drop all the understood parts of the sentence.

*note: this is scratching the surface of the nuances of ね.
