### Release Notes

<summary>getsentry/responses (responses)</summary>

###
[`v0.26.0`](https://redirect.github.com/getsentry/responses/blob/HEAD/CHANGES#0260)

[Compare
Source](https://redirect.github.com/getsentry/responses/compare/0.25.8...0.26.0)

- When using `assert_all_requests_are_fired=True`, assertions about
unfired requests are now raised even when an exception occurs in the
context manager or
decorated function. Previously, these assertions were suppressed when
exceptions occurred.
This new behavior provides valuable debugging context about which mocked
requests were
  or weren't called.
- Consider the `Retry-After` header when handling retries
