1. Bug fix in reading old persistent data using FSD_File storage driver 2. Persistence compatible with legacy format was restored for shapes a. Implemented a storage read / write wrapper for legacy persistence b. Added DRAW commands to read / write files in legacy format c. Added test cases for reading / writing operations with checking number of sub-shapes and physical properties d. Updated related sections of the development guide
