v0.5.3

0.5.3 - 2026-06-11

Fixed

• iOS HTTP worker waits are now bounded: requests that never complete are
  cancelled and reported as timeouts instead of permanently stalling the upload
  queue, and the URL session enforces a total resource timeout in addition to
  the idle timeout.
• Android HTTP connection setup failures (invalid URL, connect errors during
  body write) are returned as structured results instead of escaping as
  exceptions across the JNI boundary.
• Events now report this package's own SDK identity and version
  (amplitude-nitro-ts/<version>, experiment-nitro-ts/<version>) instead of
  stale upstream Amplitude SDK version strings.

Changed

• Updated @amplitude/analytics-core to 2.49.0, picking up the React Native
  btoa fix.
• HTTP request headers now cross the JS/native boundary as a typed
  Record<string, string> instead of a JSON string (native rebuild required).
• The native context, storage, and HTTP worker now share a single platform
  adapter instance, and storage/worker report external memory usage to the JS
  garbage collector.
• Android serves the default application context from the prefetched cache.

Added

• getNativeStartupDiagnostics().legacyMigrationSupported reports whether
  legacy Amplitude SDK SQLite migration is available (currently false;
  migrateLegacyData logs a debug notice and restores no legacy data).
• README documentation for the native architecture, the Android
  adid/appSetId privacy stance, offline usage with a connectivity listener,
  and typed Experiment variant payload access.
