[1.0.0] - 2021-11-25

Removed

• Removes the addComposerUploadProcessor function, which is no longer used in favour of addComposerUploadPreProcessor. The former was used to add preprocessors for client side uploads via jQuery file uploader (described at https://github.com/blueimp/jQuery-File-Upload/wiki/Options#file-processing-options). The new addComposerUploadPreProcessor adds preprocessors for client side uploads in the form of an Uppy plugin. See https://uppy.io/docs/writing-plugins/ for the Uppy documentation, but other examples of preprocessors in core can be found in the UppyMediaOptimization and UppyChecksum classes. This has been done because of the overarching move towards Uppy in the Discourse codebase rather than jQuery fileupload, which will eventually be removed altogether as a broader effort to remove jQuery from the codebase.

Changed

• Changes addComposerUploadHandler's behaviour. Instead of being only usable for single files at a time, now multiple files are sent to the upload handler at once. These multiple files are sent based on the groups in which they are added (e.g. multiple files selected from the system upload dialog, or multiple files dropped in to the composer). Files will be sent in buckets to the handlers they match.
