We’re currently running Couchbase 2.0.1 and looking to upgrade. I’ve reviewed the release notes here (http://www.couchbase.com/docs/couchbase-manual-2.1.0/couchbase-server-rn_2-1-0a.html) however I was curious if there is another page which details the changes more thoroughly. I am trying to verify there are no changes which might affect our code.
I would recommend you upgrade to CB 2.2.0. The new XDCR version of memory to memory is worth the upgrade.
