We are, therefore, introducing this in an incubating module, **jfx.incubator.richtext**. This will allow us to evolve the API in future releases without the strict compatibility constraints that other JavaFX modules have.

Here are a few comments on the merge of master to pick up the build changes for supporting incubator modules.

I'll get back to the API review next.

build.gradle line 2879:

> 2877: 
> 2878:     // FIXME: KCR
> 2879: //    processResources {

I recommend deleting this commented-out block unless you plan to deliver resources as part of the `jfx.incubator.input` module.

build.gradle line 2968:

> 2966: 
> 2967:     // FIXME: KCR
> 2968: //    processResources {

I recommend deleting this commented-out block unless you plan to deliver resources as part of the `jfx.incubator.richtext` module.

build.gradle line 4633:

> 4631:         project(":web")
> 4632:     ]
> 4633: 

Minor: this blank line looks like a leftover from the merge of master.
