   Hi @dianabarsan , thanks for this.
   
   I'm afraid to say that given you tested this all the way back to 1.7, this is probably a documentation error.
   
   [The code](https://github.com/apache/couchdb/blob/87edbaecd2cdb7f9266364e5fec65e31fe1fc251/src/couch/src/couch_changes.erl#L71-L78) is pretty clear that the since token is ignored when descending (`rev`) is specified. I don't know if enhancing CouchDB to support this is possible, but I'll let others respond.
   
   For now I'm changing this to an enhancement request. Once we've determined if this is possible or not, we can then decide if this goes forward in development, or instead turns into a "fix the docs" ticket instead.
