From NEWS.27:

    *** New command 'log-edit-generate-changelog-from-diff', bound to 'C-c C-w'.
    This generates ChangeLog entries from the VC fileset diff.

    *** Recording ChangeLog entries doesn't require an actual file.
    If a ChangeLog file doesn't exist, and if the new user option
    'add-log-dont-create-changelog-file' is non-nil (which is the
    default), commands such as 'C-x 4 a' will add log entries to a
    suitable named temporary buffer.  (An existing ChangeLog file will
    still be used if it exists.)  Set the user option to nil to get the
    previous behavior of always creating a buffer that visits a ChangeLog
    file.

If you use vc, then 'vc-checkin' will copy the log message from the
ChangeLog to the commit log edit buffer for you (and that I think itʼs
been doing for a long time).
