Branch iOS SDK Change Log

v.3.7.0

Added setConsumerProtectionAttributionLevel for controlling attribution data collection
Deprecated setTrackingDisabled in favor of setConsumerProtectionAttributionLevel(NONE)

v.3.6.5

Removed on-disk caching and replay of server request objects.

v.3.6.4

Added 'branch_sdk_request_unique_id' and 'branch_sdk_request_timestamp' to post params of all the SDK requests.

v.3.6.3

Fix for duplicate events created from archived request queue on disk.

v.3.6.2

Fix for issue which was sending an extra open request on cold app launch.
Updated fix for cold link launch when using deferred initialization and an AppDelegate only app.

v.3.6.1

Fixed issues where external_intent_uri was incorrectly set in certain cases

v.3.6.0

Fixes intermittent issue with universal links on cold opens

v.3.5.1

Minor logging improvement

v.3.5.0

Add additional logging
Update setRequestMetadata signature to use NSString

v.3.4.4

Fix for rare case where Branch events were duplicated
Fixed script in "Run Script" phase of static framework targets

v.3.4.3

Fix push notifications when app is backgrounded and the app uses handlePushNotification instead of handleDeeplink

v.3.4.2

Fix tvOS when using SPM

v.3.4.1

Fix cold link launch when using deferred initialization and an AppDelegate only app.
Fix cocoapods privacy manifest collision.
Fix error recovery serialization.
Update logs with more appropriate log levels.
Pass back underlying Network NSErrors that cause the SDK to give up.

v.3.4.0

Added support for setting the Branch API base URL through the branch.json file.

v.3.3.0

SDK behavior change to fix a race condition when opening a closed app with a link. In some apps, this race condition could cause the occasional loss of link data.

When opening a closed app with a link, the Branch SDK will no longer attempt to merge the app open and link arrival lifecycle events. Apps will now get called on "app open" and on "link arrival", which are often very close together. If your app ignores callbacks with no link data, then this change should be transparent.

v.3.2.0

Add support for setting DMA compliance parameters.
Update logging to allow a custom callback so clients may reroute Branch Logs to their logging infrastructure.
Update logging to use os_log private by default.
New custom server URL API. When set the SDK will always use this endpoint, the Privacy Manifest should be edited to match.
Update cocoapods, frameworks and tests to use SPM layout.
Fix crash when using pre-built xcframework on iOS 12
Improve Swift compatibility by removing API variations that differ only by an NSError.

v.3.1.0

Fix tuist SPM integration when using external by switching to a more typical SPM layout.

Note this release is only being deployed to the SPM repo to unblock tuist users. A follow up release will address compatibility between this bugfix and other integration methods.

v.3.0.1

Fix organic open when app is already running in background.

v.3.0.0

Add a Privacy Manifest for the Branch SDK. App developers may need add an App level Privacy Manifest for data they collect and pass into the Branch SDK.
- Known Issue: When using cocoapods without the use_frameworks! option, the build can fail with a duplicate privacy manifest error. Workaround is to manually merge privacy manifests.
Add support for a tracking domain. When Ads tracking is enabled, the SDK sends event calls to a tracking domain.
iOS 12 is now the min version
Xcode 15 is now the min version
Fix short URL creation via a sharesheet when tracking is disabled
Add macCatalyst checks
SetIdentity and Logout are now handled device side

CORE-1575 Add support for AdServices.framework and the Apple Attribution Token. For cocoapods, AdServices.framework is included by default. For other integration options, you should include the AdServices.framework.
CORE-1711 Reduce default SKAN timeout per FB request.
CORE-1753 Remove a debug log message to address security scanner false alarm.

v1.38.0 - Feb. 10, 2021

SDK-1106 Remove old data transfer code. Addresses a potential crash.

v0.37.0 - January 20, 2021

CORE-1198 Remove some non-inclusive terms.
- The method 'blackListURLRegex' is now named 'urlPatternsToIgnore'.
CORE-1521 Add API to attach Facebook partner parameters to Branch install, opens and events. See Facebook's documentation on advanced matching for details on valid parameters.
CORE-1316 Add support for xcframework.
- Branch.xcframework has replaced Branch.framework. iOS and tvOS are both included in the same xcframework.
- The pre-built xcframework is Branch.zip attached to the github release page.
- Carthage integrations require the '--use-xcframeworks' flag. This feature is not yet in the general carthage release, you will need to install carthage from source.
Thread safety improvement to server performance metrics. Thanks benski!

v0.36.0 - November 11, 2020

CORE-1185 Enable an App Clip to share data with the Full App
- This optional feature requires the client to setup an app group and provide the app group id to the Branch SDK.
- Full documentation for this feature will be available on the Branch docs site next week.
CORE-1184 Address security scanner warnings by removing variadic log methods, log to file and programmatic breakpoints. If you are directly using these Branch debug and log features, you will need to update your code.

v0.35.0 - August 24, 2020

With iOS 14, IDFA is only available if the app requests permission from the end user via the AppTrackingTransparency framework. The Branch SDK will not ask for it.
AdSupport is no longer included by default with Cocoapods. This fixes an app submission issue for apps that cannot contain IDFA.
INTENG-10312 iOS 14 introduces an API that conflicts with a Branch API. Refactor BranchCSSearchableItemAttributeSet init.
CORE-1146 Build dynamic, static and tvOS frameworks. Previously we only built the dynamic framework for Carthage. These prebuilt frameworks can be found in 'carthage-files/output/'
CORE-1166 Add nullability to BranchCSSearchableItemAttributeSet
SDK-449 Add support for Swift Package Manager
CORE-1209 Add optional SKAdNetwork support. If configured on the Branch Dashboard, the SDK can call SKAdNetwork on installs, opens and events.
Known issues:
- Framework import warnings in Xcode 12. We need to refactor our unit test host app.
- SPM does not support tvOS. We need to refactor some classes.

v0.23.0
- Added URL Black List for sensitive URLs (DEVEX-164).
  
  Set this property to prevent URLs with sensitive content such as oauth tokens, passwords, login data, and other data from being transmitted to Branch.
  
  The Branch SDK already ignores login URLs for Facebook, Twitter, Google, and most oauth security URLs, so it's usually unnecessary to set this parameter yourself.
  
  Set this parameter with any additional URLs that should be ignored by Branch.
- Added an SDK integration validator.
  
  Use the SDK integration validator to check that you've added the Branch SDK and handle deep links correctly when you first integrate Branch into your app.
  
  To check your integration, add the line:
```
[[Branch getInstance] validateSDKIntegration];
```
  in your application:didFinishLaunchingWithOptions: method in your app delegate. Then run your app and follow the instructions.
  
  This is for testing in development only! Make sure you remove or comment out this line of code in your release versions.
  
  See SDK Integration Validator for more information.
- Added a Deeplink Routing Validator
  
  Append validate=true to your Branch links to test and verify if they route the user to the correct content.
  
  See Deeplink Validator for more information.

- Fixing a bad key check in the CreditHistory callback, allowing NSNulls through.
v0.10.0
- Adding an automatic deep linking feature, allowing devs to register a controller to be displayed based on keys in the open dictionary.
- Adding a delegate to the BranchActivityItemProvider, allowing devs to override link items based on selected sharing network.
- Fixed a potential crash w/ the persistence item if modified while saving.
- Deprecated some additional functions for the getActivityItem: methods, trying to move away from using "and" in method naming.
- Adding a check to prevent requests from being made when the SDK is in a bad state (missing device fingerprint or session).
- Exposed the BNCConfig header in the framework.
v0.9.3
- Clearing the Link Cache on logout; links shouldn't be shared between users.
v0.9.2
- Fixing check for isReferrable. No longer automatically setting to true for handleDeepLink:, and checking against @0 since nil isn't possible.
- Making PreferenceHelper and non-singleton, and saving to file instead of using NSUserDefaults which made us prone to having our info wiped out from under us. Also keeping objects in memory, so that they don't need to be retrieved for each reference.
v0.9.1
- Fixing an issue with archiving requests when requests are allocated too early.
- Fixing a potential crash while calling close without a session.
- Lots of readme updates.
v0.9.0

- Cleaning up the Link Cache.
- Adding Bundle ID to Open / Install requests.
- Fixing an issue causing double escaped params.
v0.8.2

v0.8.1
- Fix potential for bad reference when no callback is provided to redeemRewards call.
v0.8.0
- Split up all requests into their own classes to make them unit testable.
- Replace base64 implementation which could potentially crash.
- Remove most logic from the PreferenceHelper.
v0.7.8

- Fixing bad content type in prepareGetRequest.
- Creating scripts for an automated release process.
- Fixing a bad callback in processNextQueueItem, potentially causing a crash.
- Adding and documenting all of the new constants added in the Branch initSession callback.
v0.7.7 Changing the time for update state checks to give better install attribution.
v0.7.6
- Exposing isUserIdentified to allow devs to understand if Branch has a User Identity set.
- Removing all instances of bnc_no_value from the SDK.
- Creating a separate error code for Branch being down vs a request failing
- Fixing a bug where and error would cause queue processing to stop, and pending request to be failed.
v0.7.5 Prefixing constants to avoid collisions with other frameworks.
v0.7.4
- Fixing key usage throughout the SDK. When you call getTestInstance or getInstance:, the proper key will now make it through to requests.
- Cleaning up debug logic internally. The static usage of setDebug is now deprecated, please move toward using the instance method.
v0.7.3
- Fixing Branch down check (>= 500 instead of > 500).
- Removing tag from all BNCServerInterface methods.
- Moving request retry delay off the main thread.
- Removing committed CocoaPod files.
v0.7.2
- Added docs to the header, compatible with AppleDoc and available on cocoadocs.org.
- De-coupling all of the Branch dependencies to make them injectable. This will significantly improve test stability.
- Clearing all Branch related items when the Branch key being used in the app changes. This prevents invalid items from making it to the server.
v0.7.1 Adding a missing item to the pod spec headers.
v0.7.0
- Large rewrite of the internals of Branch.m to make things more stable, predictable, readable, and maintainable.
- Added callbacks to the redeemRewards methods.
- Updating Queue persistence to be non-immediate. Rather than persisting to disk on every change, it persists after time has elapsed to prevent hanging issues when in a loop.
- Making errors more specific -- now you actually get the error message back, instead of a generic one.
- Fixing issue with BranchActivityItemProvider when using the Twitter share sheet.
- Removing temporary backwards compat typedefs.
v0.6.3:
- Addressing an issue identified by iHeartRadio where decoding a JSON string could cause crashes.
- Adding the ability to opt out of the app list check.
v0.6.2:
- Fixing an issue with the newest Facebook app not working with the ShareSheet unless an NSURL is present.
- Fixing user url generation for getShortUrl failure callbacks.
- Fixing a couple issues with setDebug.
- Using NS_ENUMs.
- Removing remaining internal setUriScheme code.
- Cleaning up update state logic.
v0.6.1: Issue with requests in the queue having their data updated when they were immutable. Updating BNCServerRequest interface to prevent this from happening in the future.
v0.6.0: We have deprecated the use of bnc_app_key and are now using branch_key, which can be obtained in the settings page of your Dashboard. The replacement in the SDK should happen in the plist, as well as in +(Branch *)getInstance:(NSString *)branchKey; if necessary.
v0.5.9: Revert of the URI Scheme updates.
v0.5.8:
- Fixing an issue with the creation of NSError userInfo dictionaries.
- Updating behavior of URI Scheme detection -- you should now name the scheme you want to use "io.branch.sdk." The previous behavior will be maintained for some time.
- You can additionally specify which scheme to use via [[Branch getInstance] setUriScheme:@"myapp://"]
v0.5.7: Adding handling around the Facebook share sheet to prevent incorrect link clicks. Removing branch_key warning message.
v0.5.6: Issue sending proper update to server if isReferrable not set
v0.5.5: Reverting branch_key change until server component is updated. Fixing an issue with getShortUrl failures causing crashes.
v0.5.4: A large number of changes have been included in this version, but all are backwards compatibile.
- Retry Number has been added to all requests, so that the server is able to differentiate.
- Organization of some of the encoding methods in the repository has been centralized.
- Fixed an encoding bug with empty param dictionaries and arrays.
- A couple of encoding issues were fixed, and a large number of tests have been added.
- Perhaps most importantly, the branch_key is now replacing the bnc_app_key and app_id items. For now, both will continue to work, but the non-branch_key items are deprecated, and will be removed with 0.6.0.
- The presence of app_id and branch_key has been ensured across all requests, no longer piecemeal.
v0.5.3: Follow up to 0.5.2, now looks at Documents directory creation date and considers this to be the original app install date
v0.5.2: Recent iOS update resets bundle file creation date on update, messing with our update/install detection method
