Release 4.1.0

New Features

• afterEventOf(...event) function construct an AfterEvent registrar always sending event.
• ValueTracker.clear() function to unregister all value receivers.

Bug Fix

• OnEvent.thru() transforms and sends all events received during receiver registration.

Release 4.0.1

Packaging

• Build CommonJS main module instead of UMD

Release 4.0.0

This is a rework of the API.

The exported symbols and interfaces are renamed:

• Events are sent by EventSender and received by EventReceiver.
• The EventKeeper keeps the last sent event.
• The event receiver registrar function interfaces are called OnEvent and AfterEvent.
• The DOM events receiver registrar function interface is called OnDomEvent.

The EventInterest is able to inform on events exhausting. Its interface is extended:

• The done property becomes true when events exhausted.
• The whenDone() method registers events exhausting callbacks.
• The off() method now accepts an optional reason of interest lost. It always informs on event exhausting now.

Release 3.3.0

New Features

• Add CachedEventProducer extending EventProducer and implementing CachedEventSource.
• Build event producers from event sources with EventProducer.from() and CachedEventProducer.from() static methods.
• Allow to sync with nested event sources using extended ValueTracker.by() and ValueSync.sync() methods.
• Allow directional ValueSync synchronization with ValueTracker by passing optional direction argument to sync() method.

Release 3.2.1

Packaging

• Drop browser bundle.
• Do not minify bundles.
• Make bundles terser-friendly.

Incompatible Changes

• EventInterest.none is replaced with noEventInterest() function
• EventSource.on is renamed to onEventKey
• CachedEventSource.each is renamed to afterEventKey
• StateUpdater is renamed to StateConsumer
• StateUpdater namespace is removed
• EventInterest is a class now and sgould be constructed with eventInterest() function

Release 3.1.1

API Changes

• Laxed event source API.
  EventSource.on() and CachedEventSource.each() are just an event consumer registration methods, not necessarily an EventProducer implementations.

Release 3.1.0

New Features

• Make EventProducer.thru() consumer last in chain. Such consumer may be called multiple times or not called at all.
• Remove EventArgs as they are no longer used.
• Introduce EventNotifier. A minimal event emitter implementation not implementing EventProducer.

Breaking Changes

• Removed EventArgs interface.
• EventProducer.thru() behaviour changed. E.g. the events may be filtered, or the same event consumer may be called multiple times per event.

v3.0.2

Fixes

• Update documentation with the latest changes
• DomEventDispatcher: Remove DOM elements-specific signatures

Release 3.0.0

New Features

• DOM events support

Breaking Changes

• this parameter is no longer supported by event consumers.
• Changed generic signatures to always contain event and return types.

Release 2.2.0

Packaging

• Main module is ES6 now
