+        Please take the time to rule out issues with your code or third party libraries before filing a bug report. If you are reporting an error, try to determine whether the error is coming from Jasmine, another library, or your own code.
+
+        Check the [FAQ](https://jasmine.github.io/pages/faq.html) and any other relevant [documentation](https://jasmine.github.io/pages/docs_home.html) to see if your issue has already been addressed.
+
+        ## Special troubleshooting steps for asynchronous scenarios
+        If the issue has to do with testing asynchronous code, please read the [async tutorial](https://jasmine.github.io/tutorials/async) and the async section of the FAQ. In particular, check for the following common errors:
+
+        * Are you trying to write a synchronous test for asynchronous code?
+        * Does the test signal completion before the code under test finishes?
+        * Do expectations run before the code that they're trying to verify?
+
+        ## Try the latest version of Jasmine
+        If at all possible, upgrade to the latest versions of `jasmine-core` and any other relevant packages (e.g. `jasmine`, `jasmine-browser-runner`). If you can't do that, please check the [release notes](https://github.com/jasmine/jasmine/tree/main/release_notes) for all newer versions to make sure that the bug hasn't already been fixed.

+
+        ## Troubleshooting
+        Please take the time to rule out problems with your code or third party libraries before opening an issue. If you're running into an error, try to determine whether the error is coming from Jasmine, another library, or your own code.
+
+        Check the [FAQ](https://jasmine.github.io/pages/faq.html) and any other relevant [documentation](https://jasmine.github.io/pages/docs_home.html) to see if your question has already been answered. Consider searching [Stack Overflow](https://stackoverflow.com/questions/tagged/jasmine) and past issues in this repository for related questions as well.
+
+        ## Special troubleshooting steps for asynchronous scenarios
+        If the issue has to do with testing asynchronous code, please read the [async tutorial](https://jasmine.github.io/tutorials/async) and the async section of the FAQ. In particular, check for the following common errors:
+
+        * Are you trying to write a synchronous test for asynchronous code?
+        * Does the test signal completion before the code under test finishes?
+        * Do expectations run before the code that they're trying to verify?
+
+        ## Consider asking Angular questions in an Angular forum
+
+        Questions like "how do I test this Angular service" are mostly about Angular, not Jasmine. You'll likely get better responses in an Angular forum. Here's a rule of thumb: If you can't demonstrate the problem without Angular, you probably have an Angular question.
+
+        ## Try the latest version of Jasmine
+        If at all possible, upgrade to the latest versions of `jasmine-core` and any other relevant packages (e.g. `jasmine`, `jasmine-browser-runner`).
+
+        ## Put together a [minimal, reproducible example](https://stackoverflow.com/help/minimal-reproducible-example)

 # A JavaScript Testing Framework
 
 Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, [Node.js](http://nodejs.org) projects, or anywhere that JavaScript can run.

 For evergreen browsers, each version of Jasmine is tested against the version of the browser that is available to us
 at the time of release. Other browsers, as well as older & newer versions of some supported browsers, are likely to work.
 However, Jasmine isn't tested against them and they aren't actively supported.

+# Jasmine 4.2.0 Release Notes
+
+## New Features
+
+* Added a jasmine.is asymmetric equality tester
+  * Allows the use of === comparisons for specific fields of an object that
+    should otherwise be compared with the default deep value equality logic.
+  
+## Bug Fixes
+
+* More reliably report errors that occur late in the suite/spec lifecycle
+  * Previously, an error that occurred after Jasmine started to report the
+    suiteDone or specDone event for the current runable would not be reliably
+    reported. Now such an error is reported on the nearest ancestor suite whose 
+    suiteDone event has not yet been reported.
+
+* Don't report a deprecation when a runnable uses two forms of async
+  * This was made into an error in 4.0, so the deprecation is redundant.
+
+* Include property getter values in pretty-printed objects

+# Jasmine 4.4.0 Release Notes
+
+## Changes
+
+* Optimized the process of transitioning between specs in Node, Safari, and
+  Edge. This change reduces the run time of jasmine-core's own test suite by
+  50-70% in Node, about 20% in Edge, and 75-90% in Safari. Your results may
+  vary. In general, suites with many fast specs will see the greatest
+  performance improvement.
+
+* Removed old code to support browsers that don't provide 
+  addEventListener/removeEventListener.

+# Jasmine Core 5.0.0-alpha.0 Release Notes
+
+## Summary
+
+This release primarily adds support for parallel execution via the `jasmine`
+package. Please see its release notes and the 
+[parallel documentation](https://jasmine.github.io/tutorials/running_specs_in_parallel)
+for more information. Additionally, this release cleans up a few outdated
+interfaces.
+
+This is a pre-release for a major version. It contains breaking changes, and
+there may be further breaking changes between this release and the final 5.0.0
+release.
+
+## Breaking changes
+
+* Use addEventListener in browsers rather than setting window.onerror
+
+  This simplifies error handling in browsers, makes Jasmine's own integration
+  tests easier to debug, and provides stack traces for more unhandled
+  exceptions. However, some browsers will provide less error information when
+  the error comes from a file:// URL. Additionally, Jasmine will no longer
+  override existing onerror handlers, and setting window.onerror will no longer
+  override Jasmine's global error handling. (Use `jasmine.spyOnGlobalErrors`
+  instead.)
+
+* Made Env#execute async
+* Env#execute no longer takes a callback
+* The `boot` function exported by the core module returns the same object
+  every time it's called.
+* Removed node_boot.js. Use the exported `boot` function instead.
+
+### Changes to supported environments
+
+The following previously supported environments are no longer supported:
+
+* Node <16.14
+* Safari 14
+* Firefox 91
+
+Although this release may still work in some of those environments, we no
+longer test against them and won't try to maintain compatibility with them in
+future releases.
+
+## New features
+
+* Support for parallel execution in Node.js using the `jasmine` package
+
+## Bug fixes
+
+* The global error handler is uninstalled at the end of env execution.
+
+## Supported environments
+
+jasmine-core 5.0.0-alpha.0 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 16.14+,         18 |

+## Changes

+* Optionally restore the pre-5.0 behavior of boot() always creating a new instance

+  need to create and use multiple envs in sequence.

+# 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).
