Minor comments:

  . please make the @anchor be a separate line, as it was before
  . the first sentence ("Is a query sent...") sounds awkward, suggest
    to reword "This is sent when connection is first ..."
  . please make sure to leave 2 spaces between sentences, per our
    conventions
  . please provide a suitable log message and ChangeLog change

Thanks.
