We’ve been using Java SDK 1.4.x since we started using Couchbase. It has worked well.
I know the 2.x SDK is out (and has been for a while now). But we’re a small shop and it just hasn’t been a priority to upgrade (especially without any issues with 1.4.x).
Are there known issues or expected problems with staying on 1.4.x? We expect to upgrade at some point, but what are the benefits of upgrading? Are there known drawbacks to continuing with 1.4.x? Is it known if/when 1.4.x will no longer function (i.e. couchbase 4? later version?)?
