+# Jasmine Core 4.6.1 Release Notes
+
+## Summary
+
+This is a one-time backport of bug fixes from 5.x, for the benefit of Karma
+users who may not be aware that they're still using 4.x.
+
+No further 4.x releases are planned. If possible, you should upgrade to the
+latest 5.x instead of 4.6.1. If you're using Karma, you can do this by 
+installing jasmine-core 5.x and adding an override to package.json:
+
+```
+{
+    // ...
+    "overrides": {
+        "karma-jasmine": {
+            "jasmine-core": "^5.0.0"
+        }
+    }
+}
+```
+
+## Bug Fixes
+
+* Removed unnecessary throw when building 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).
+
+* Accessibility: Always provide a non-color indication that a spec is pending
+
+* Accessibility: Improved contrast of version number and inactive tab links
+
+## Supported environments
+
+jasmine-core 4.6.1 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 12.17+, 14, 16, 18 |
