Bump version to 5.5.0

This is off by default for backwards compatibility but can be enabled
by setting the forbidDuplicateNames env config property to true.

Fixes #1633.

 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. 
 
+\* Environments that are past end of life are supported on a best-effort basis.
+They may be dropped in a future minor release of Jasmine if continued support
+becomes impractical.

 To find out what environments work with a particular Jasmine release, see the [release notes](https://github.com/jasmine/jasmine/tree/main/release_notes).

+# 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.

+# Jasmine Core 5.4.0 Release Notes
+
+## Changes
+
+* Fixed de-duplication of exception messages containing blank lines on Node and Chrome
+
+  This is particularly helpful when reporting testing-library errors, which
+  have messages that contain blank lines and can be hundreds or even thousands
+  of lines long.
+
+* Document that the expected and actual properties of expectation results are deprecated
+
+  The values of these properties are not reliable in configurations where 
+  reporter messages are JSON serialized. They appear to have been seldom if ever 
+  used. They will be removed in the next major release. 
+
+* Added Firefox 128 (current ESR) to supported browsers
