Bug Fixes

  • This library now uses JSpecify nullness annotations, which are type-use. Kotlin developers should use the following compiler arguments to enforce correct usage: -Xjspecify-annotations=strict, -Xtype-enhancement-improvements-strict-mode (Ib5eb3, b/326456246)
  • Deprecated androidx.core.os.CancellationSignal. Usages should be replaced with the platform-provided android.os.CancellationSignal. (Id45f6, b/309499026, b/309054079)
