### Release Notes

<details>
<summary>google/truth
(com.google.truth.extensions:truth-java8-extension)</summary>

### [`v1.2.0`](https://togithub.com/google/truth/releases/tag/v1.2.0):
1.2.0

- Fixed a bug that caused ProtoTruth to ignore the contents of unpacked
`Any` messages. This fix may cause tests to fail, since ProtoTruth will
now check whether the message contents match. If so, you may need to
change the values that your tests expect, or there may be a bug in the
code under test that had been hidden by the Truth bug. Sorry for the
trouble.
([`8bd3ef6`](https://togithub.com/google/truth/commit/8bd3ef613))
- Added `isWithin().of()` support to `IntegerSubject` and `LongSubject`.
([`6464cb5`](https://togithub.com/google/truth/commit/6464cb5ca),
[`0e99a27`](https://togithub.com/google/truth/commit/0e99a2711))

### [`v1.1.5`](https://togithub.com/google/truth/releases/tag/v1.1.5):
1.1.5

[Compare
Source](https://togithub.com/google/truth/compare/v1.1.4...v1.1.5)

- Updated Truth to depend on [Guava
32.0.1](https://togithub.com/google/guava/releases/tag/v32.0.1). The
previous Guava version, 32.0.0, contained a bug under Windows, which did
not affect Truth's functionality but [could cause
problems](https://togithub.com/google/truth/issues/1137) for people who
use Guava's I/O functionality in their codebase. Affected users can
already manually update their Guava dependency to 32.0.1, but if they
don't depend directly on Guava, they may find it easier to upgrade to
this new Truth release instead.
- Fixed `IterableOfProtosSubject` to produce a proper failure message
instead of NPE when the actual value is `null`.
