### Release Notes

<details>
<summary>google/truth (com.google.truth:truth)</summary>

### [`v1.4.3`](https://togithub.com/google/truth/releases/tag/v1.4.3): 1.4.3

-   Added more nullness information to our APIs (in the form of [JSpecify](https://jspecify.dev/) annotations). This could lead to additional warnings (or even errors) for users of Kotlin and other nullness checkers. Please [report any problems](https://togithub.com/google/truth/issues/new). ([`ee680cb`](https://togithub.com/google/truth/commit/ee680cbaf))
-   Deprecated `Subject.Factory` methods for Java 8 types. We won't remove them, but you can simplify your code by migrating off them: Just replace `assertAbout(foos()).that(foo)` with `assertThat(foo)` (or `about(foos()).that(foo)` with `that(foo)`). ([`59e7a50`](https://togithub.com/google/truth/commit/59e7a5065))
