 # 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.
 
-Documentation & guides live here: [http://jasmine.github.io](http://jasmine.github.io/)

+# 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
+
+## Documentation Updates
+
+* Removed duplicate Suite and Spec jsdocs
+
+## Supported environments
+
+jasmine-core 4.2.0 has been tested in the following environments.
+
+| Environment       | Supported versions |

+| Node              | 12.17+, 14, 16, 18 |

+# Jasmine 4.3.0 Release Notes
+
+## New Features
+
+* Added [`jasmine.spyOnGlobalErrorsAsync`](https://jasmine.github.io/api/4.3/jasmine.html#.spyOnGlobalErrorsAsync), 
+  to better support testing code that's
+  expected to produce unhandled exceptions or unhandled promise rejections
+  * Fixes [#1843](https://github.com/jasmine/jasmine/issues/1843)
+  * Fixes [#1453](https://github.com/jasmine/jasmine/issues/1453)
+
+## Documentation updates
+
+* Updated the README to reduce redundancy and update support links
+
+## Internal improvements
+
+* Split `Env` into several smaller classes 
+* Replaced uses of `var` with `const`/`let`
+* Replaced most uses of `self = this` with arrow fns
+* Removed obsolete and unused utility fns
+* Separated reporter- and runable-specific queue runner configuration
+* Added more test coverage for default spy strategies
+* Converted integration specs to `async`/`await`

+# 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.
