Bump version to 4.2.0

This removes quite a bit of indirection from result processing, at the
cost of making a few of the tests more awkward.

+# Jasmine 4.1.1 Release Notes
+
+## Summary
+
+This release fixes several bugs involving equality comparison of properties
+with Symbol keys.
+
+## Bug fixes
+
+* Fixes for crash bugs and output problems when comparing objects with Symbol keys
+  * Include symbol properties in matcher diffs
+  * Fixed exception when comparing arrays with Symbol keys
+  * Include symbol properties in matcher diffs
+  * Include symbol keys when pretty-printing objects
+  * Fixes [#1966](https://github.com/jasmine/jasmine/issues/1966)
+
+* Exclude non-enumerable symbol properties from equality comparison
+  * Merges [#1963](https://github.com/jasmine/jasmine/pull/1963) from @suke

+# 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
+
