- CFB prevent infinite loop (h/t @rossj) - pass updated eslint checks (fixes #1726 h/t @BjoernRave) - defined name proper encoding (fixes #1785 h/t @laohe98) - correct theme color order (fixes #389 h/t @foreverpw) - ODS / XLML more aggressive flagging of stub cells - cellStyles implies sheetStubs - updated SSF to 0.10.3
