v1.0.0-beta2

• [Breaking] Remove ulog.Logger interface and expose *zap.Logger directly.
• [Breaking] Upgrade zap to v1.0.0-rc.3 (now go.uber.org/zap, was
  github.com/uber-go/zap)

  testing practices. Not a breaking change as nobody is using this func
  themselves according to our code search tool.

  min version 2.1.0
  and use jaeger's adapters for jaeger and tally initialization.

• [Breaking] Rename modules/rpc to modules/yarpc
• [Breaking] Make new module naming consistent yarpc.ThriftModule to
  yarpc.New, task.NewModule
  to task.New
• [Breaking] Rename yarpc.CreateThriftServiceFunc to yarpc.ServiceCreateFunc
  as it is not thrift-specific.
• Report version metrics for company-wide version usage information.
• DIG constructors now support returning a tuple with the second argument being
  an error.

v1.0.0-beta1

This is the first beta release of the framework, where we invite users to start building services on it and provide us feedback. Warning we are not promising API compatibility between beta releases and the final 1.0.0 release. In fact, we expect our beta user feedback to require some changes to the way things work. Once we reach 1.0, we will provider proper version compatibility.
