- eliminated functional constructs in hot functions - format try-catch block extracted into new function - cpexcel + codepage updated to 1.2.0 - more efficient (and correct) clean implementation of RGB/HSL/tint algorithms - xlsx binary --all option enables every extra formatting and saving option - column widths parsed and saved (requires cellStyles:true)
