v0.3

Features & Improvements:

• Support constructing RetinaNet, data loader, optimizer, COCOEvaluator without configs, in addition to Mask R-CNN.
• Add DeepLab & PanopticDeepLab in projects/.
• Support importing 3 projects (point_rend, deeplab, panoptic_deeplab) directly with import detectron2.projects.xxx.
• Support mixed precision in training (using cfg.SOLVER.AMP.ENABLED) and inference.
• Support ADE20k semantic segmentation dataset (named ade20k_sem_seg_train, ade20k_sem_seg_val).
• Continuous build on Windows.

Pre-built Linux binaries are provided for the following environment:
