Couchbase Go Core

This package provides the underlying Couchbase IO for the gocb project. If you are looking for the Couchbase Go SDK, you are probably looking for gocb.

Branching Strategy

The gocbcore library maintains a branch for each major revision of its API. These branches are introduced just prior to any API breaking changes with a internal version code of vX-dev. Once a version is fully assembled and prepared to ship, the version will be updated to reflect a specific full version number (ie vX.0.0), and a tag created for that version number.

An example of this is the v6 branch was created just prior to a breaking change. The v6 branch will contain all changes that have a new API until a release is made (and tag v6.0.0 is created). At which point, any future API changes will be made on branch v7.
