allow developers to fix on a specific google viz library version, rather than forcing upgrades

[orwant]

What would you like to see us add to this API?

There is always a risk that a new version of the library could introduce a
regression (as the most recent release did, in that hovers no longer work
in IE8 in IE7 compatibility mode).  While it is great that google is
providing release candidates for early testing, it would be even better if
google could simply retain a few (2 or 3?) versions of the library so that
developers could fix their code to run against a particular version and
then not have to worry that a new version would break existing
functionality.  A 6 month deprecation policy (or the like) would be
extremely helpful, and would give developers more confidence in being able
to use google viz in production environments.

What component is this issue related to (PieChart, LineChart, DataTable,
Query, etc)?

This version control is very important to serious users of your API, who cannot manage
a product without it.  Additionally, this would make the Visualization API consistent
with other Google APIs.
