Version 6.1

• extend syntax of `\state' command (thermodynamics)
• add reactants module to the errorcheck module
• fix bug in Danish translation
• rename module chemformula > formula
• put reactions in the chemfig method in between \schemestart and \schemestop (formula)
• replace deprecated \Lewis with \Charge in method chemfig (formula)
• choose the formula method if either mhchem or chemformula are loaded; choose chemformula if there is a conflict (formula)
• use last instead of first found method for defining floats (scheme)
• new option scheme/float-method (schemes)
• new option reactions/own-counter (reactions)
• new option reactions/autoref-name (reactions)
• deprecate option reactions/tocbasic (reactions)
• make \autoref work with reaction environments (reactions)
• fix support for cleveref and fancyref with reactions (reactions)
• reorganization of deprecation, removal, and patching
• rename nomenclature/format into nomenclature/latin-format (nomenclature)
• new option nomenclature/iupac-format (nomenclature)
• properly implement and document user modules (i.e., styles) as opposed to chemmacros' own modules; since v6 \ChemModule has a new function which is why \ChemStyle is introduced
• add load-time option stop which can prevent modules and styles from being loaded
