Announcement text:
This is an update to version 2.00.

The mhchem bundle consists of two packages: mhchem and rsphrase.

The mhchem package provides commands for typesetting chemical molecular formulae and equations.
What's new?
- a new versioning system that tries to incorporate old
  and improved syntax into one file.
- the command \cee which can take & and \\ as input, for
  use in equation environments
- \ce now works in text mode as well
- new symbol added: ^.
- basic support for bonds: A-B=C#D
- math inside formulae can be achived using \cmath
- new option for reaction arrows: ->C[+H2O] is a
  shortcut for ->[\ce{H2O}]

The rsphrase package contains the text of all official Risk and Safety (R and S) Phrases that are used to label chemicals. At the time being, these phrases are available in Englisch, Danish, French and German (current spelling).

What's new?
- French phrases. Thanks to Dominique Richard for his work.
- bugfixes

Thanks for the update.
