• Fixed issue where the member stresses table in the summary report was not matching the main summary table. This was because the member stresses table was checking bending stresses whereas the main summary was not. The member stresses table has been changed so that it does NOT check bending stresses since these stresses won't actually be experienced by the members in reality. So only axial, torsion, shear and combined stresses are checked by both tables now.

v5.8.3 - 16 July 2022

• 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'.
