Release: AWS SDK for iOS 1.2.1

The sample app demonstrates how mobile applications can use Amazon Simple Email Service (Amazon SES) to record user feedback without additional infrastructure.

The new Amazon Elastic Compute Cloud API version 2012-03-01 introduces new API actions to support volume status checks. Volume status checks provide information about the I/O (read/write) capability of your Amazon Elastic Block Store (Amazon EBS) volume. The status check lets you know when an EBS volume's data is potentially inconsistent.

The AWS Security Token Service (AWS STS) client in the SDK has been updated to properly handle time zone settings when converting a date string to a NSDate object.

The AmazonLogger class has new methods for logging which are helpful in iOS5.1. Based on a change in iOS5.1 the verbose logging only works in development mode and should be turned off for release builds or your app may crash. To help faciliate this change all samples have been update with a new recommended logging setup as shown here:

            #ifdef DEBUG
                [AmazonLogger verboseLogging];
            #else
                [AmazonLogger turnLoggingOff];
            #endif
        

There is a known issue with the AmazonLogger in "verbose mode" in iOS5.1 with release builds (AdHoc/AppStore distributions). The AWS SDK for iOS v1.2.1 has a fix and we recommend including the following code segment to prevent your app from crashing:

            #ifdef DEBUG
                [AmazonLogger verboseLogging];
            #else
                [AmazonLogger turnLoggingOff];
            #endif
        

• Bucket names can include '+' symbols in the name, but the '+' symbol does not get replaced in URL encodings and can result in spaces in bucket names instead.
• It is possible to create an object with a key which includes characters that are not valid XML characters, which will cause an error in the response to the AmazonS3Client listObjects method.
