okio v1.13.0 Release Notes

  • 2017-05-12

    • Okio now uses @Nullable to annotate all possibly-null values. We've added a compile-time dependency on the JSR 305 annotations. This is a [provided][maven_provided] dependency and does not need to be included in your build configuration, .jar file, or .apk. We use @ParametersAreNonnullByDefault and all parameters and return types are never null unless explicitly annotated @Nullable.

    • Warning: this release is source-incompatible for Kotlin users. Nullability was previously ambiguous and lenient but now the compiler will enforce strict null checks.
