• add more detail to progress (steps, stages, and tiles) (include stages and tiles in pipeline progress #192)
• batch status updates (reduce traffic on the /ready endpoint #238)
• generate preview thumbnails of very large images (generate thumbnails for large images #322)
• retain image metadata during chain pipelines, especially grid stages (grid mode images do not have metadata #453)
• add a horizontal layout to the web UI (add horizontal UI layout for wide monitors #460)
• add support for horde safety plugin (add support for the horde-safety plugin #461)
• read metadata from input images (read previous parameters from img2img and inpainting sources #462)
• wait until the end of a job to calculate and report output filenames (images are lost when using grid mode with batch size > 1 #463)
• drag and drop images and metadata files to load their parameters (drag and drop images and metadata files onto the web UI to load their parameters #464)
• make JSON metadata and profiles more complete (EXIF is still compatible with auto1111)
• client-side parameter validation
• update localizations
  • de
  • en
  • es
  • fr
• update release tests
  • grid mode
  • highres
  • passing within --mse 1
• update docs
  • new API endpoints
  • web UI query parameters
  • using horde-safety plugin

Stretch goals:

• save partial profiles, omit some parameters
• use existing components when switching diffusers pipeline but keeping the same model
