iOS agent release notesRSS

Notes

Improvements

• Improved network instrumentation performance resulting from a change in the way we detect the network connection type, which also prevents the potential for a deadlock under high concurrency.
• The agent will raise an exception with detailed information in the event it detects a fatal conflict where another library interferes with our code instrumentation.

Fixes

• Resolves an issue with ASI instrumentation that could cause a crash when receiving certain network level errors.
• Resolves a deadlock scenario that could occur during certain high-load circumstances. 
• Fixes an issue where heavy network load could potentially cause the OS Reachability functionality to hang, forcing the OS to terminate the app on launch. 
• NewRelic.h was updated to correct syntax issues causing compiler warnings.

Notes

Improvements

• Improved logging to identify when crash reporting is disabled during debugging.
• You can now disable the capture of the HTTP response body for requests by calling the disableFeature method and passing the flag NRMAFeatureFlag_httpResponseCapture.
• Added support for the armv7s architecture as it is not available in Xcode 6.
• The SDK was updated to accept the HTTP method in the signature of the [NewRelic noticeNetworkRequestForURL] and [NewRelic noticeNetworkFailureForURL] methods allowing more detailed information to be collected.
• The version of the New Relic iOS agent was added to the comments in NewRelic.h for convenience.

Fixes

• Corrected a potentially crashing situation when calling [NewRelic noticeNetworkRequestForURL].
• Updated SDK to include iOS agent symbols in crash reports that may include New Relic code.
• Removed potential deadlock on main thread for reachability requests by moving reachability flags off the main thread.
• Resolves a crashing issue with Swift related to cases where class_getSuperClass() was called with the root Swift class.

Notes

Improvements

• Crash reporting
  • This release introduces crash reporting for mobile apps. Crash reporting supports capture and reporting of unhandled Objective-C runtime exceptions as well as native crashes like segfaults and bus errors.
  • Crashes include Interaction trails: a history of automatically instrumented actions that occurred during the app session leading up to the crashing event. No breadcrumbs needed.
  • The SDK includes a [NewRelic crashNow] method to trigger a test crash quickly and easily.
  • When an app is built for release, the debugging symbols are sent to New Relic (via a dSYM file) to automatically provide human-readable crash reports in the UI.
• Swift app compatibility
  • This release can be safely included in Swift applications. While we do not yet support instrumentation of Swift code, the New Relic SDK is now capable of instrumenting the Objective-C code included in your Swift app.
• More configuration options
  • An expanded runtime configuration API now supports disabling of crash reporting and interaction tracing, as well as enabling experimental Swift instrumentation for dynamically invoked methods.

Notes

Fixes

• Fixed minor memory leak caused by network instrumentation.
• Fixed a bug where network data was missing from interaction traces.

Notes

Fixes

• Corrected edge case that caused network requests to fail in a 400 error.
• Corrected issue causing New Relic Cross Application Tracing to fail.

Fixes

• Stability improvements: Certain application design patterns could trigger a concurrency problem in the New Relic SDK that caused app instability. This version properly handles those edge cases.

Notes

Fixes

• Stability improvements: Certain application design patterns could trigger a concurrency problem in the New Relic SDK that caused app instability. This version properly handles those edge cases.
• A memory leak in NRMATraceMachine has been removed.

Notes

Fixes

• Resolved issue that corrupted New Relic interaction trace data, and resulted in a "ThreadLocalTrace is not parentTrace" log message.

Notes

Improvements

• Fixed build errors in NewRelicFeatureFlags.h that occurred if NewRelic.h was imported before foundation.h in the prefix.pch file.
• Interaction traces period is more discrete. An interaction will only record traces until a new interaction is started, rather than combining the data into one interaction.
• The method +[NRTaskQueue dequeue] will no longer fire on the UI thread.
• Interaction traces now have more easily identifiable names. Instead of “ViewController#Method” they will now be named “Display ViewController”.
• The healthy interaction timer will no longer fire repeatedly over very short intervals.
• The agent will no longer crash if the instrumented method:; [NSURLConnection sendAsynchronousRequest:queue:completionHandler:] is passed a nil completionHandler.

Fixes

• Default interaction traces can now be renamed by adding @protocol NewRelicCustomInteractionInterface( (defined in NewRelic.h) to the traced view controller.
• Added new method for starting a custom interaction trace +startInteractionWithName: (defined in NewRelic.h)
• Deprecated the following methods in NewRelic.h : +startInterationFromMethodName:object:, +startInterationFromMethodName:object:customizedName, and +startInterationFromMethodName:object:cancelRunningTrace:. Use +startInteractionWithName: instead.
• Added method +stopCurrentInteraction: to NewRelic.h. Allows user to stop a custom interaction trace manually.
