 chemfig 1.3

  * All parameters are now set via \setchemfig{} with <key>=<value> syntax.
    The following macros, though still working, are now obsolete:
    \setcrambond, \setatomsep, \setbondoffset, \setdoublesep,
    \setangleincrement, \enablefixedbondlength, \disablefixedbondlength,
    \setnodestyle, \setbondstyle, \setlewis, \setlewisdist, \setstacksep,
    \setcompoundstyle, \setarrowdefault, \setandsign, \setarrowoffset,
    \setcompoundsep, \setarrowlabelsep, \enablebondjoin, \disablebondjoin
    and \schemedebug

  * The starred version "\chemfig*" and the optionnals arguments "\chemfig[][]",
    though still, working are obsolete.
    The \setchemfig macro should be used instead.

  * 6 new parameters: "lewis radius", "arrow double sep", "arrow double coeff",
    "arrow double harpoon", "cycle radius coeff", "arrow head", all set via
    \setchemfig

  * Bugfix in \CF at parse@mergeopt

  * Code cleaning.

  * Macro \polymerdelim (undocumented), included in the code:
    this macro is exprimental and still in test.

  * No write register allocated by \newwrite
