     * We do this because `jasmine.js` and `jasmine-html.js` are auto-generated (as you've seen in the previous steps) and accepting multiple pull requests when this auto-generated file changes causes lots of headaches

+# Jasmine Core 3.6 Release Notes
+
+## Summary
+
+This is a maintenance release of Jasmine with a number of new features and fixes.
+
+## Highlights
+
+* Added support for custom object formatters
+    * Allows customizing how an object is stringified in matcher failure messages
+    * [Tutorial](https://jasmine.github.io/tutorials/custom_object_formatter)
+    * [API reference](https://jasmine.github.io/api/3.6/jasmine.html#.addCustomObjectFormatter)
+
+* Don't require matchers and asymmetric equality testers to pass custom object formatters back to Jasmine
+    - Supports custom object formatters.
+    - Makes it easier to write high quality matchers and asymmetric equality testers.
+    - The old API will still work until 4.0.
+
+* Properly import jasmineRequire object before using
+    - Improves compatibility with Webpack
+    - Merges [#1766](https://github.com/jasmine/jasmine/pull/1766) from @amilligan
+
+* Added a toHaveBeenCalledOnceWith matcher
+    - Merges [#1801](https://github.com/jasmine/jasmine/pull/1801) from @Maximaximum
+    - Fixes [#1717](https://github.com/jasmine/jasmine/issues/1717)
+    
+* Added a toHaveSize matcher
+    - Merges [#1796](https://github.com/jasmine/jasmine/pull/1796) from @wokier
+
+* Added a toBePending async matcher
+    - Merges [#1808](https://github.com/jasmine/jasmine/pull/1808) from @DCtheTall
+    - Fixes [#1803](https://github.com/jasmine/jasmine/issues/1803)
+    
+* Added support for user-defined spec/suite properties
+    - Allows specs/suites to pass data to custom reporters
+    - Merges [#1763](https://github.com/jasmine/jasmine/pull/1763) from @johnjbarton
+
+* Route unhandled promise rejections to onerror
+    - Merges [#1778](https://github.com/jasmine/jasmine/pull/1778) from @johnjbarton
+    - Fixes [#1777](https://github.com/jasmine/jasmine/issues/1777)
+
+
+## Internal notes
+
+* Use a version of eslint that works on Node 8
+
+* Check for syntax and standard library objects that don't work in IE
+
+* Run eslint against all files
+
+* Add Additional Test for equals Matcher
+    - Merges [#1829](https://github.com/jasmine/jasmine/pull/1829) from @tobiasschweizer
+    - Fixes [#1821](https://github.com/jasmine/jasmine/issues/1821)
+
+* Depend on head of jasmine-browser to fix IE failures in CI
+
+* Fixed test failure in Firefox 74
+
+* Added test for resolveTo/rejectWith with empty parameters
+    - Merges [#1802](https://github.com/jasmine/jasmine/pull/1802) from @chivesrs
+    
+* Removed unnecessary uses of new in tests
+
+* Realigned the browser testing matrix to match current reality
+    - Use Windows instead of Linux so we can get current browsers from Sauce.
+    - Test against the version of Firefox that corresponds to ESR as well as
+  latest.
+    - Test the latest Edge rather than a specific older version.
+    - Test Safari 8 and 13 instead of 8, 9 and 10. What works in those versions
+  is likely to work in the ones in between.
+
+* Don't leak global error handlers between Jasmine's own tests
+
+* Added basic property tests for matchersUtil.equals
+
+* Added integration tests for existing matcher interfaces
+
+* Added integration tests for asymmetric equality testers
+
+* Test IE before other browsers on Travis
+
+
+## Other Changes
+
+* Show diffs involving root-level asymmetric equality testers
