v1.2.0

• dig.In and dig.Out now support value groups, making it possible to
  produce many values of the same type from different constructors. See package
  documentation for more information.

v1.1.0

• Added the dig.RootCause function which allows retrieving the original
  constructor error that caused an Invoke failure.
• Errors from Invoke now attempt to hint to the user a presence of a similar
  type, for example a pointer to the requested type and vice versa.

v1.0.0

First stable release: no breaking changes will be made in the 1.x series.

• Provide and Invoke will now fail if dig.In or dig.Out structs
  contain unexported fields. Previously these fields were ignored which often
  led to confusion.

v1.0.0-rc2

• Added variadic options to all public APIS so that new functionality can be
  introduced post v1.0.0 without introducing breaking changes.
• Functions with variadic arguments can now be passed to dig.Provide and
  dig.Invoke. Previously this caused an error, whereas now the args will be ignored.
• Exported dig.IsIn and dig.IsOut so that consuming libraries can check if
  a params or return struct embeds the dig.In and dig.Out types, respectively.

v1.0.0-rc1

First release candidate.

v0.5.0

• dig.In and dig.Out now support named instances, i.e.:

  type param struct {
    dig.In
  
    DB1 DB.Connection `name:"primary"`
    DB2 DB.Connection `name:"secondary"`
  }

• Structs compatible with dig.In and dig.Out may now be generated using
  reflect.StructOf.

v0.4.0

• [Breaking] Remove Must* funcs to greatly reduce API surface area.
• [Breaking] Restrict the API surface to only Provide and Invoke.
• Providing constructors with common returned types results in an error.
• [Breaking] Update Provide method to accept variadic arguments.
• Add dig.In embeddable type for advanced use-cases of specifying dependencies.
• Add dig.Out embeddable type for advanced use-cases of constructors
  inserting types in the container.
• Add support for optional parameters through optional:"true" tag on dig.In objects.
• Add support for value types and many built-ins (maps, slices, channels).

v0.3

API renaming and introducing Invoke functionality

• Rename RegisterAll and MustRegisterAll to ProvideAll and
  MustProvideAll.
• Add functionality to Provide to support constructor with n return
  objects to be resolved into the dig.Graph
• Add Invoke function to invoke provided function and insert return
  objects into the dig.Graph

v0.2

API cleanup and removal of the global graph

• Rename Register to Provide for clarity and to reduce clash with other
  Register functions.
• Rename dig.Graph to dig.Container.
• Remove the package-level functions and the DefaultGraph.

v0.1

This version is all about singleton objects: create them, share them in the graph through constructors, or by registering a pointer directly.
