JSpecify 1.0 provides standardized nullness annotations to improve Java code clarity and prevent null-related bugs by introducing `@Nullable`, `@NonNull`, `@NullMarked`, and `@NullUnmarked`. These annotations help make null handling more predictable and integrate seamlessly with tools like IntelliJ IDEA, Error Prone, and NullAway for robust static analysis. JSpecify facilitates incremental adoption in legacy projects and offers support for generics, enhancing overall code safety and reliability.

<p>It should be built into the language similar to Kotlin and C#. I don’t need yet another framework for adding annotations.</p>
