Hi Flo,

if I'm not completely mistaken, the changes feed does contain the last
revision of a modified document or a deletion stub. See the following
example:
$ curl -X GET '
http://localhost:5984/test/_changes?feed=continuous&heartbeat=3000'
# (some changes)
# fire foff
$ curl -X PUT 'http://localhost:5984/test/bla' -d '{}'
{"ok":true,"id":"bla","rev":"1-967a00dff5e02add41819138abb3284d"}
# produces changes feed
{"seq":4,"id":"bla","changes":[{"rev":"1-967a00dff5e02add41819138abb3284d"}]}
# fire off
$ curl -X DELETE '
http://localhost:5984/test/bla?rev=1-967a00dff5e02add41819138abb3284d'
{"ok":true,"id":"bla","rev":"2-eec205a9d413992850a6e32678485900"}
# produces changes feed
{"seq":5,"id":"bla","changes":[{"rev":"2-eec205a9d413992850a6e32678485900"}],"deleted":true}

2-eec205a9d413992850a6e32678485900 is in fact the deletion stub's revision
ID

hope if helps - otherwise pls. let us know

Best
      Sebastian
