### Release Notes

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

### [`v1.4.2`](https://togithub.com/google/truth/releases/tag/v1.4.2):
1.4.2

This release is the final step of copying all our methods from `Truth8`
to `Truth`. If you have not already migrated your usages from `Truth8`
to `Truth`, you may see build errors:

OptionalSubjectTest.java:39: error: reference to assertThat is ambiguous
        assertThat(Optional.of("foo")).isPresent();
        ^
both method
assertThat(@&#8203;org.checkerframework.checker.nullness.qual.Nullable
Optional<?>) in Truth8 and method
assertThat(@&#8203;org.checkerframework.checker.nullness.qual.Nullable
Optional<?>) in Truth match

In most cases, you can migrate your whole project mechanically: `git
grep -l Truth8 | xargs perl -pi -e 's/\bTruth8\b/Truth/g;'`. (You can
make that change before upgrading to Truth 1.4.2 or as part of the same
commit.)

If you instead need to migrate your project incrementally (for example,
because it is very large), you may want to upgrade your version of Truth
incrementally, too, following our instructions for
[1.3.0](https://togithub.com/google/truth/releases/tag/v1.3.0) and
[1.4.0](https://togithub.com/google/truth/releases/tag/v1.4.0).

#### For help

Please feel welcome to [open an
issue](https://togithub.com/google/truth/issues/new) to report problems
or request help.

#### Changelog

- Removed temporary type parameters from `Truth.assertThat(Stream)` and
`Truth.assertThat(Optional)`. This can create build errors, which you
can fix by replacing all your references to `Truth8` with references to
`Truth`.
