• fxtest: Add WithTestLogger option that uses a testing.TB as the
  Fx event logger.
• An fxevent logger that can log events using a slog logger has been added.

Thanks to @robbert229 for their contribution to the release.

• Provided, Decorated, Supplied, and Replaced events now include a trace
  of module locations through which the option was given to the App.
• wasi support.

Added

• A new event fxevent.Run is now emitted when Fx runs a constructor, decorator,
  or supply/replace stub.

• Upgrade Dig dependency to v1.17.0.

v1.19.3

Changed

• Fixed several typos in docs.

• Annotating In and Out structs with From/As annotations generated invalid results.
  The annotation check now blocks this.
• Shutdown: Support calling from Invoke.

Deprecated

• Deprecate ShutdownTimeout option.

v1.19.2

Changed

• Upgrade Dig dependency to v1.16.1.

v1.19.1

Changed

• Calling fx.Stop() after the App has already stopped no longer errors out.

Fixed

• Addressed a regression in 1.19.0 release which caused apps to ignore OS signals
  after running for startTimeout duration.

v1.19.0

Added

• fx.RecoverFromPanics Option which allows Fx to recover from user-provided constructors
  and invoked functions.
• fx.Private that allows the constructor to limit the scope of its outputs to the wrapping
  fx.Module.
• ExitCode ShutdownOption which allows setting custom exit code at the end of app
  lifecycle.
• Wait which returns a channel that can be used for waiting on application shutdown.
• fxevent/ZapLogger now exposes UseLogLevel and UseErrorLevel methods to set
  the level of the Zap logs produced by it.
• Add lifecycle hook-convertible methods: StartHook, StopHook, StartStopHook
  that can be used with more function signatures.

Changed

• fx.WithLogger can now be passed at fx.Module level, setting custom logger at
  Module scope instead of the whole App.

Fixed

• fx.OnStart and fx.OnStop Annotations now work with annotated types that was
  provided by the annotated constructor.
• fxevent/ZapLogger: Errors from fx.Supply are now logged at Error level, not
  Info.
• A race condition in lifecycle Start/Stop methods.
• Typos in docs.

v1.18.2

Added

• Clarify ordering of Invokes in Modules.

Fixed

• Fix Decorate not being applied to transitive dependencies at root App level.
