> chemmacros:
> - new commands \NewChemIUPAC, \LetChemIUPAC, \NewChemParticle
>   \NewChemNMR, \NewChemPhase, \NewChemReaction, \RenewChemReaction
>   \NewChemState
> - added macro names with more meaningfule names to each of the
>   one-letter name commands
> - changed behaviour of \DeclareChem<...> to match 
>   \DeclareRobustCommand, i.e., no check if command is defined; added
>   a \NewChem variant to each that /does/ check; use \NewChem<...>
>   instead of \DeclareChem<...> for definitions
> - new iupac command \dento
> - new option choice `nmr/pos=super'
> - bug fix in appearance of coupling nuclei
> - new possibilities for formatting the output of the NMR coupling
>   constants output with \J:
>   `coupling-pos=side/sub', `coupling-nuclei-pre',
>   `coupling-nuclei-post', `coupling-bonds-pre',
>   `coupling-bonds-post', `coupling-symbol'
> - internal changes to the greek letter mapping selection mechanism
> - deprecate package option `strict'
> - deprecate package option `cmversion': also all backwards 
>   compatibility for version 1 has been dropped
> - drop command \mhName

> - new option stoich-print
> - new command \chstoich

> chemgreek:

> - new mappings `textalpha' (cf the package with the same name, part
>   of `greek-fontenc')
> - \chemgreek_new_mapping:nnn redefined so that package name must be
>   given if needed; \chemgreek_activate_mapping:n now issues a warning
>   if the needed package hasn't been loaded
> - if hyperref has been loaded with package option `unicode' and the
>   `textalpha' package has been loaded, too, we can use greek letters
>   in PDF bookmarks
> - new command \printchemgreekmapping
> - \showchemgreekmapping now writes information to the log instead of
>    the file
