Allow uploading multiple files from your computer at once. The maximum limit is 100 files at once. There is still a 50MB size limit that applies to the whole upload. This limit is at the Nginx level. The upload widget no longer shows a thumbnail preview of the uploaded file. This is because there isn't room for it in a multi-file upload, and because the next page will show a preview anyway after the files are uploaded. Direct file uploads are processed synchronously, so they may be slow. API change: the `POST /uploads` endpoint now expects the param to be `upload[files][]`, not `upload[file]`.
Components
Components are used to encapsulate common UI widgets used throughout the site. This includes things like comments, tag lists, post thumbnails, paginators, and other things used repeatedly throughout the site. Components encapsulate a widget's HTML, CSS, and Javascript together so that all the code for a component is in a single place.
This uses the ViewComponent library.
Components are similar in concept to React components.
