Couchbase Go Core v8 Alpha

This package provides the underlying Couchbase IO for the gocb project. This package is the alpha version of the upcoming v8 release, if you are looking for the official stable package then use gocbcore.

If you are looking for the Couchbase Go SDK, you are probably looking for gocb for stable or gocb2alpha for the alpha corresponding to this package.

Branching Strategy

The gocbcore library maintains a branch for each previous major revision of its API. These branches are introduced just prior to any API breaking changes. Active work is performed on the master branch, with releases being performed as tags. Work made on master which are not yet part of a tagged released should be considered liable to change.
