Version 3.16.1

Version 3.16.1

Bugfixes:

• iOS/macOS: Preserved report error.type classification when native Apple crash capture is enabled. Client/native dynamic attributes are now applied as defaults before report data is constructed, so report-scoped attributes (error.type, error.message, _mod_fingerprint) are no longer overwritten by native values.
  Managed exception reports keep their Exception/Unhandled exception classification, while native crash reports remain error.type=Crash.
• Unity: Fixed parsing issue with native stack frames without symbol information.
  Frame parsing is now extracted into a dedicated BacktraceRawStackTraceParser with defensive bounds checks and additional unit-test coverage.

Version 3.16.0

Version 3.16.0

Improvements :

WebGL

• Add diagnostics for Unity log-callback exception reports where Unity supplies an exception message but an empty stackTrace string.
• Add WebGL-default observation of original exceptions passed through Debug.LogException(exception) by wrapping Debug.unityLogger.logHandler.
• Add stack-source classification for Unity log-callback reports:
  • original_exception_stacktrace
  • unity_log_callback_stacktrace
  • unavailable
• Add optional browser JavaScript stack-at-capture annotation for stackless Unity log-callback reports. This is disabled by default and is supplemental context only.

Unity

• Preserve Unity log/source context even when a report has no stack frames.
• Preserve enriched report attributes and annotations through background-thread queueing.
• Improve thread safety for background log handling and log-manager access.

Release notes:

- This release does not synthesize managed C# frames when Unity provides neither a callback stack nor an original exception object with a usable stack. 
In that case, the report is explicitly classified as stackless and preserves the best available diagnostic context.

Version 3.15.1

Version 3.15.1

Improvements

WebGL:

• Add support for offline reports storage and deferred submission.
• Ensure offline crash persistence works when Backtrace is initialized while offline.
• Enable offline persistence by default for WebGL runtime builds initialized via BacktraceClient.Initialize(url).
• Move WebGL offline replay and filesystem flush logic from BacktraceClient into BacktraceDatabase to better align with SDK architecture.
• Add write-ahead persistence to the PlayerPrefs-backed fallback queue to prevent data loss when send callbacks do not execute due to browser lifecycle teardown.
• Improve rate-limit handling by preserving stored records and excluding HTTP 429 responses from retry attempts.
• Improve WebGL mobile browser stability (Android Chrome / iOS Safari):
  • Avoid per-frame PlayerPrefs compaction to prevent excessive storage I/O, jank, and battery drain.
  • Improve resilience of PlayerPrefs access under browser storage constraints (e.g. browsing-modes / quota limits).
  • Harden IDBFS persistence by debouncing and guarding FS.syncfs calls.
  • Rely on modern browser lifecycle signals (pagehide, visibilitychange, freeze, blur) instead of unreliable unload events.

macOS:

• Update Backtrace native plugin bundle layout to comply with Unity and Apple bundle requirements and prevent undefined behaviour during native crash handling
