Name of contribution: chemmacros Author's name: Clemens Niederberger Package version: 4.3 Location on CTAN: macros/latex/contrib/chemmacros/ Summary description: A collection of macros to support typesetting chemistry documents License type: lppl

Announcement text given by the package's contributor:

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

chemformula:

• 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 option stoich-print
• new command chstoich

chemgreek:

• rename Chem<name => chem<name>, the old names will issue warnings but still work
• 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

thanks for the upload; i've installed the new version, and updated the catalogue repository.
