# Jasmine Core 5.1.0 Release Notes

## Changes

* Exclude inherited Error properties from stack trace

* Fixed error when formatting Error object with non-Error cause property

  Merges [#2013](https://github.com/jasmine/jasmine/pull/2013) from @angrycat9000.

  Fixes [#2011](https://github.com/jasmine/jasmine/issues/2011).
  
* Added `throwUnless` and `throwUnlessAsync`

  These are similar to `expect` and `expectAsync` except that they throw
  exceptions rather than recording matcher failures as spec/suite failures.
  They're intended to support using Jasmine matchers in [testing-library's](https://testing-library.com/)
  `waitFor`, and also provide a way to integration-test custom matchers.

  Fixes [#2003](https://github.com/jasmine/jasmine/issues/2003).

  Fixes [#1980](https://github.com/jasmine/jasmine/issues/1980).
