v1.14.0

Added

• Introduce the new fx.WithLogger option. Provide a constructor for
  fxevent.Logger objects with it to customize how Fx logs events.
• Add new fxevent package that exposes events from Fx in a structured way.
  Use this to write custom logger implementations for use with the
  fx.WithLogger option.
• Expose and log additional information when lifecycle hooks time out.

Changed

• Fx now emits structured JSON logs by default. These may be parsed and
  processed by log ingestion systems.
• fxtest.Lifecycle now logs to the provided testing.TB instead of stderr.
• fx.In and fx.Out are now type aliases instead of structs.

v1.13.1

Fixed

• Fix minimum version constraint for dig. fx.ValidateGraph requires at least
  dig 1.10.

v1.13.0

Added

• Added fx.ValidateGraph which allows graph cycle validation and dependency correctness
  without running anything. This is useful if fx.Invoke has side effects, does I/O, etc.

v1.12.0

Added

• Added fx.Supply to provide externally created values to Fx containers
  without building anonymous constructors.

Changed

• Drop library dependency on development tools.

v1.11.0

Added

• Value groups can use the flatten option to indicate values in a slice should
  be provided individually rather than providing the slice itself. See package
  documentation for details.

v1.10.0

Added

• All fx.Options now include readable string representations.
• Report stack traces when fx.Provide and fx.Invoke calls fail. This
  should make these errors more debuggable.

Changed

• Migrated to Go modules.

v1.9.0

Added

• Add the ability to shutdown Fx applications from inside the container. See
  the Shutdowner documentation for details.
• Add fx.Annotated to allow users to provide named values without creating a
  new constructor.

v1.8.0

Added

• Provide DOT graph of dependencies in the container.

v1.7.1

Fixed

• Make fxtest.New ensure that the app was created successfully. Previously,
  it would return the app (similar to fx.New, which expects the user to verify
  the error).
• Update dig container to defer acyclic validation until after Invoke. Application
  startup time should improve proportional to the size of the dependency graph.
• Fix a goroutine leak in fxtest.Lifecycle.

v1.7.0

Added

• Add fx.ErrorHook option to allow users to provide ErrorHandlers on invoke
  failures.
• VisualizeError returns the visualization wrapped in the error if available.
