v1.0.0-rc1

• [Breaking] Providing types into fx.App and invoking functions are now
  options passed during application construction. This makes users'
  interactions with modules and collections of modules identical.
• [Breaking] TestLifecycle is now in a separate fxtest subpackage.
• Add fx.Inject() to pull values from the container into a struct.

v1.0.0-beta4

• [Breaking] Monolithic framework, as released in initial betas, has been
  broken into smaller pieces as a result of recent advances in dig library.
  This is a radical departure from the previous direction, but it needed to
  be done for the long-term good of the project.
• [Breaking] Module interface has been scoped all the way down to being
  a single dig constructor. This allows for very sophisticated module
  compositions. See go.uber.org/dig for more information on the constructors.
• [Breaking] package config has been moved to its own repository.
  see go.uber.org/config for more information.
• fx.Lifecycle has been added for modules to hook into the framework
  lifecycle events.
• service.Host interface which composed a number of primitives together
  (configuration, metrics, tracing) has been deprecated in favor of
  fx.App.

v1.0.0-beta3

• [Breaking] Environment config provider was removed. If you were using
  environment variables to override YAML values, see
  config documentation for more information.
• [Breaking] Simplify Provider interface: remove Scope method from the
  config.Provider interface, one can use either ScopedProvider and Value.Get()
  to access sub fields.
• Add task.MustRegister convenience function which fails fast by panicking
  Note that this should only be used during app initialization, and is provided
  to avoid repetetive error checking for services which register many tasks.
• Expose options on task module to disable execution. This will allow users to
  enqueue and consume tasks on different clusters.
• [Breaking] Rename Backend interface Publish to Enqueue. Created a new
  ExecuteAsync method that will kick off workers to consume tasks and this is
  subsumed by module Start.
• [Breaking] Rename package uhttp/client to uhttp/uhttpclient for clarity.
• [Breaking] Rename PopulateStruct method in value to Populate.
  The method can now populate not only structs, but anything: slices,
  maps, builtin types and maps.
• [Breaking] package dig has moved from go.uber.org/fx/dig to a new home
  at go.uber.org/dig.
• [Breaking] Pass a tracer the uhttp/uhttpclient constructor explicitly, instead
  of using a global tracer. This will allow to use http client in parallel tests.

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)
• Remove now-unused config.IsDevelopmentEnv() helper to encourage better
  testing practices. Not a breaking change as nobody is using this func
  themselves according to our code search tool.
• Log traceID and spanID in hex format to match Jaeger UI. Upgrade Jaeger to
  min version 2.1.0
  and use jaeger's adapters for jaeger and tally initialization.
• Tally now supports reporting histogram samples for a bucket. Upgrade Tally to 2.1.0
• [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.
