Release Notes

google/truth (com.google.truth:truth)

v1.4.4

• Annotated the rest of the main package for nullness, and moved the @NullMarked annotation from individual classes up to the package to avoid a warning under --release 8. (e107aea)
• Improved the failure message for matches to conditionally suggest using containsMatch. (7e9fc7a)

v1.4.3: 1.4.3

• Added more nullness information to our APIs (in the form of JSpecify annotations). This could lead to additional warnings (or even errors) for users of Kotlin and other nullness checkers. Please report any problems. (ee680cb)
• 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)
