    chemfig 1.7
    -----------
    1. To draw a horizontal reaction a new environment is provided: \hreac...\endhreac
    2. The strut of the previous atom is no longer added to the argument of \printatom
    The key 'use atom strut', when set to true, reverts to the previous behavior 3. When 'use atom strut' is 'false', each atom is typeset in a TeX box only once,
    whereas previously it was sometimes 5 times or more

    chemfig v1.71
    -------------
    * bugfix: too many incorrect bond connections with the new definition of
    \CF_ifzerodim. Back to the previous definition (macro \CF_ifzerodim used
    only if the key "use atom strut" is true).
    * bugfix: optional argument \chemfig or \chemname taken into account in hreac
    environment.
    * bugfix:in hreac environment, the argument of \^{<dim>} or \>{<dim> }is no
    longer evaluated at 0pt if in ex or em.
    * the macro \name{<name>} has on optionnal argument [<dim>]
    * warning if non empty optional arguments of \schemestart are used
    * the key "name sep" is now set to 1.5ex by default and is the value used
    if the optional argument of \chemname is empty. --------------------------------------------------------------------------------
