chemformula
package.
Version number: 4.8 License type: lppl1.3
Summary description: Command for typesetting chemical formulas and reactions.
Announcement text: ----------------------------------------------------------------------
This is technically not a new package: it used to be part of the chemmacros bundle but from now on (v4.8) it will be distributed on its own.
Other news: this version fixes a bug in typeseting single bonds that has been introduced with the last update.
