• NEW: 'Materials' have been separated from 'Sections' and must be defined outside of the section builder. However, these materials can be used within the section builder. This suits the new plates and composite sections. Old files created before v2.0.0 should automatically be adjusted for these changes.
• NEW: Files can now be auto-saved (activate this from your 'Account Settings' → 'User Settings' → 'File Manager Settings' → 'Autosave Files'.
