got exception when trying to create an S3 class according to the readme about aws-sdk-php-zf2

[jeskew]

Your second line should read $s3 = $aws->createS3(); or $s3 = $aws->createClient('S3'); when working with the currently release of this module. I updated the readme in e667eed.

tried updating with your code provided, however now I'm getting the following exception:

InvalidArgumentException

File:

    /var/www/dev.hub/vendor/aws/aws-sdk-php/src/ClientResolver.php:328

Message:

    Missing required client configuration options: 

    version: (string)

      A "version" configuration value is required. Specifying a version constraint
      ensures that your code will not be affected by a breaking change made to the
      service. For example, when using Amazon S3, you can lock your API version to
      "2006-03-01".

      Your build of the SDK has the following version(s) of "s3": * "2006-03-01"

      You may provide "latest" to the "version" configuration value to utilize the
      most recent available API version that your client's API provider can find.
      Note: Using 'latest' in a production application is not recommended.

      A list of available API versions can be found on each client's API documentation
      page: http://docs.aws.amazon.com/aws-sdk-php/v3/api/index.html. If you are
      unable to load a specific API version, then you may need to update your copy of
      the SDK.

if I go back and add the version key to the aws.local.php then it works, so you may want to update the readme for that as well.
