Hello again :-).
I've run out a major memory leak with attachments in cblite 1.1, and since you are working on the next release, I think you are should be aware of it.
The problem is that when I get an attachment (no matter how - through the url or through the getAttachment method), it doubles in the memory and stays in it forever.
Moreover, it happens both with the sqlite and the forestdb engines.
Maybe the couse is that I did something wrong (I don't experienced enough with objC to know this for sure), but I just replaced ios/vendor/couchbase-lite-ios/ with the new one from cblite's repository. And the code is the same that works without problems with the current release.
here the screen from the instruments:

You can see the pairs of allocations of the same size. When I get an attachment again, the new couple of the alocations appears with almost the same time and stays in memory forever.
