@@ -3,11 +3,14 @@ NoFlo ChangeLog
 
 ## 1.2.0 (git master)
 
+* Ported NoFlo from CoffeeScript to ES6
 * Deprecated constructing networks with `new noflo.Network`. Use `noflo.createNetwork` instead, with the following options available:
   - `subscribeGraph: true`: Uses `LegacyNetwork` which modifies network topology based on changes in graph. This can cause some types of errors to be silent.
   - `subscribeGraph: false`: Uses `Network`: network topology can be changed with network's methods (`addNode`, `removeEdge`, etc) and will be also written to the graph.
   For backwards compatibility reasons, `subscribeGraph` defaults to `true`. Adapt your applications to use `false` instead and start utilizing Network methods for any changes to a running graph.
 * Added support for a more standard `noflo.createNetwork(graph, options, callback)` signature, with backwards compatibility for the legacy `noflo.createNetwork(graph, callback, options)` signature
+* Removed support for `noflo.WirePattern`. WirePattern has been deprecated since 1.0, and all code using it should be migrated to the latest Process API
+* Removed support for changing component icon and description statically (on class level) at run-time (i.e. `ComponentName::icon = 'new-icon'`). Component icon and description should be set in class constructor or in `getComponent` instead. Changing icon and description for a specific instance (process) is not affected and is fully supported
