For your use case you might look at these versioning techniques:

the changes feed only shows the update sequences for the current documents
in the database. it doesn't show sequences for old revisions of documents
because they will go away after compaction anyway.

every time a document is updated it removes it's previous sequence from the
by-sequence index and the revision information is only available by querying
for it on the document itself (until you compact).

All,

Good afternoon.

using this url
http://10.0.0.10:5984/test/_changes?since=14966&all_docs=true

I get the following results

{"results":[

now if I make an amendment to the document at sequence number 15006 and
using the same URL I get the following results.

I think that it is fairly straight forward to ascertain that we are looking
at latest revision sequences.

Is there a way to see all sequence numbers?? I am of course aware of the
continuous feed but do not wish to use it.
My use case is for a pharma regulated clinical trials database where i need
a total audit of every single change made to the database.

best regards
