I'm pleased to announce the 11.1.0 release of the AdWords API Ruby
Client Library, adwords4r. It is packaged as a Ruby gem archive and
can be installed with the "gem install adwords4r" command. For those
who don't use the gem environment, you can also download it from
http://code.google.com/p/google-api-adwords-ruby/

 The changes in version 11.1.0 are as follows:

- Added additional attributes to the AdWords::Error::ApiError class.
  This should make it easier to get all the useful SOAP fault
information, some of which wasn't available in the previous version.
  The extra attributes
are :trigger_ex, :soap_faultcode_ex, :soap_faultstring_ex,
and :code_ex
- Added static methods to the AdWords::API class to retrieve API unit
usage information.
  AdWords::API.get_total_units() will return the a running total of
API units used since the API was initialized.
  AdWords::API.get_last_units() will return the number of API units
used for the last API call.
- Started the process of creating new sample code. The existing code
samples are a bit lacking and were moved to the 'examples/old'
directory.
  A new sample program, 'examples/reports.rb' was created. This sample
validates, schedules, and downloads a Keyword Structure report.
  It's a fairly extensive sample and illustrates some of the new API
features as well as general best-practices.
  Look for more sample code in future releases.
