Announcement text:
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.

chemfig – Draw molecules with easy syntax
The package provides the command \chemfig{<code>}, which draws molecules using the TikZ package. The <code> argument provides instructions for the drawing operation.
While the diagrams produced are essentially 2-dimensional, the package supports many of the conventional notations for illustrating the 3-dimensional layout of a molecule.
The package uses TikZ for its actual drawing operations.
