• Remove NSLog() from PayPal One Touch Core (Issue #223 and #226)
• Fix nullability annotation in PPFPTITracker.h to squelch error in Xcode 7.3 Beta (PR #227, thanks @sberrevoets!)

4.1.3

• Prevent crash when BTPayPalDriver instantiates SFSafariViewController with an invalid URL, and return an error instead
• Update BTTokenizationService allTypes property to be NSArray <NSString *>

4.1.2 - Workaround for conflict with Alamofire

• Workaround for Swift compiler bug that causes BTJSON to conflict with Alamofire (see Issue #195)
  • For the merchant apps that read their configuration directly from BTJSON via Objective-C, you may need to switch from dot syntax to square brackets to call BTJSON methods
• Ignore UIAlertView deprecation warning in BTDropInErrorAlert

4.1.1 - Drop-in for cards only

• Fixed a bug that caused Drop-in view controller to show an empty BTPaymentButton when PayPal and Venmo are disabled
• Updated Kount to 2.6.2

4.0.2 - Drop-in fetches payment methods automatically

• If the Client Token has a Customer ID, Drop-in will automatically fetch the customer's vaulted payment methods.
  • A bug in 4.0.0-4.0.1 prevented Drop-in from fetching payment methods even if a Customer ID is provided in the Client Token; apps needed to call fetchPaymentMethodsOnCompletion before presenting Drop-in.
  • You can still call fetchPaymentMethodsOnCompletion to pre-fetch payment methods, so that Drop-in doesn't need to show its own loading activity indicator.
• Prevent calling requestsDismissalOfViewController on iOS 8 when there is nothing to dismiss. (Merge #199 - thanks, @Reflejo!)
• Drop-in Add Payment Method fixes
  • Show/hide CVV and postal code fields without flicker
• Use Save bar button item in upper right to add additional payment methods
• BTPayPalDriver will not call BTAppSwitchDelegate callback methods when SFSafariViewController is presented (Issue #188)

4.0.1 - Drop-in fixes

• Braintree/Data has been renamed to Braintree/DataCollector.
• See our Braintree iOS SDK v4 migration guide for more details.
• As always, feel free to open an Issue with any problems or suggestions that you have.
