Summary:
In iOS 7 negative currency values for the locale en_US are surround by brackets, as it should be for financial negative values. See http://ux.stackexchange.com/a/1875

Since iOS 7.1 (including iOS 8) this has changed and negative values are not surrounded anymore by brackets.

If this is the indented behaviour (what I do not believe), if would be nice to have it stated somewhere in the release notes.

Steps to Reproduce:
1. Create a NSNumberFormatter for currency style

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterCurrencyStyle;

2. Set the locale to be en_US

formatter.locale = [NSLocale localeWithLocaleIdentifier:@"en_US"];

3. Create a string from a negative value

NSString *string = [formatter stringFromNumber:@(-20.10)];

Expected Results:
The variable `string` should be @"($20.10)"

Actual Results:
On iOS 7.1 and higher the string is @"-$20.10"


Version:
iOS 7.1

Notes:
Run the attached Xcode project on iOS 7.0 and iOS 7.1/8.0 beta 4 and see the printed string for locale "en_US" and you will see the differences.

I've also attached the app output in txt files for iOS 7.0, 7.1 and 8.0
