Please add release notes.

Could we make option in what style should fixes work?
I didn't find in google docs that `TODO(...)` is considered deprecated and I personally would like to get fixes in older format other than new `TODO: ... - ` format.

To keep codebases consistent, we should provide a way to choose fixes style.
