Release Notes for SPFx Package Version 1.4

What is new in this release?

All Projects

@microsoft/sp-build-web

• Enable build assets to be incorporated into the *.sppkg file and hosted by SharePoint

@microsoft/sp-build-core-tasks

• Add "asyncComponents" option to config.json. This setting can be used to avoid imports that would cause a library to be accidentally loaded synchronously instead of asynchronously

• Fix an issue where localization files for extensions were overwritten
• Enable skipLibCheck to work around the inconsistent declarations of "WeakMap" in lodash and es2015.collection
• Fix an issue with data bindings for the Knockout web part template
• Add a suppression for the "CSS class 'ms-Grid' is not camelCase" warning caused by Fabric
• Add launch.json and extensions.json to the generator SharePoint solution
