-        Jasmine is supported by volunteers working in their free time. Although we're generally willing to help, we're going to ask you to put in some effort first to help us help you.
-
-        ## Troubleshooting
-        Please take the time to rule out problems with your code or third party libraries before opening an issue. If you're running into an error, try to determine whether the error is coming from Jasmine, another library, or your own code.
-
-        Check the [FAQ](https://jasmine.github.io/pages/faq.html) and any other relevant [documentation](https://jasmine.github.io/pages/docs_home.html) to see if your question has already been answered. Consider searching [Stack Overflow](https://stackoverflow.com/questions/tagged/jasmine) and past issues in this repository for related questions as well.
-
-        ## Special troubleshooting steps for asynchronous scenarios
-        If the issue has to do with testing asynchronous code, please read the [async tutorial](https://jasmine.github.io/tutorials/async) and the async section of the FAQ. In particular, check for the following common errors:
-
-        * Are you trying to write a synchronous test for asynchronous code?
-        * Does the test signal completion before the code under test finishes?
-        * Do expectations run before the code that they're trying to verify?
-
-        ## Consider asking Angular questions in an Angular forum
-
-        Questions like "how do I test this Angular service" are mostly about Angular, not Jasmine. You'll likely get better responses in an Angular forum. Here's a rule of thumb: If you can't demonstrate the problem without Angular, you probably have an Angular question.

 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. 
 
+\* Supported on a best-effort basis. Support for these versions may be dropped
+if it becomes impractical, and bugs affecting only these versions may not be
+treated as release blockers.

+# 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
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment       | Supported versions      |
+|-------------------|-------------------------|
+| Node              | 18, 20, 22              |
+| Safari            | 15-17                   |
+| Chrome            | 129*                    |

+| Edge              | 129*                    |
+
+\* Evergreen browser. Each version of Jasmine is tested against the latest
+version available at release time.<br>
+\** 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.

+* Optionally enforce uniqueness of spec and suite names
+
+  This is off by default for backwards compatibility but can be enabled
+  by setting the `forbidDuplicateNames` env config property to true.
+  Fixes [#1633](https://github.com/jasmine/jasmine/issues/1633).

+# Jasmine Core 5.6.0 Release Notes

+## Changes
+
+* Added [toHaveNoOtherSpyInteractions](https://jasmine.github.io/api/5.6/matchers.html#toHaveNoOtherSpyInteractions) matcher
+  * Merges [#2051](https://github.com/jasmine/jasmine/pull/2051) from @Eradev

+

+  * Merges [#2045](https://github.com/jasmine/jasmine/pull/2045) from @MattMcCherry
+
+* Improved error messages when non-promises are passed to built-in async matchers
+  * Merges [#2049](https://github.com/jasmine/jasmine/pull/2049) from @andiz2
+  * Fixes [#2037](https://github.com/jasmine/jasmine/issues/2037)
+
+* Added [toHaveClasses](https://jasmine.github.io/api/5.6/matchers.html#toHaveClasses) matcher
+  * Merges [#2046](https://github.com/jasmine/jasmine/pull/2046) from @aYorky 
+
+## Documentation updates
+
+* Demoted Safari to best-effort support
+  
+  Due to limited availability of Safari versions for contributors and maintainers
+  as well as in CI, Safari will be supported on the same best-effort basis as
+  environments that are past end of life, such as previous Firefox ESR versions. 
+  See [this discussion](https://github.com/jasmine/jasmine/discussions/2050) for
+  more information about why this change was made and what to expect.

+# Jasmine Core 5.7.0 Release Notes
+
+## New features
+
+* Added [Clock#autoTick](https://jasmine.github.io/api/5.7/Clock.html#autoTick)
+  to automatically tick the clock asynchronously
+  * Merges #2042 from @atscott and @stephenfarrar
+  * Fixes #1725
+
+* Expose [spec path](https://jasmine.github.io/api/5.7/Spec.html#getPath) as an
+  array of names in addition to the existing concatenated name
+
+  This is meant to support tools like IDE integrations that need to filter a run
+  to an exact set of suites/specs.
+
+
+## Documentation improvements
+
+* Documented that [SpecResult#filename](https://jasmine.github.io/api/5.7/global.html#SpecResult)
+  and [SuiteResult#filename](https://jasmine.github.io/api/5.7/global.html#SuiteResult)
+  are wrong when zone.js is present and in some cases where it/describe/etc are
+  replaced
+* Updated docs for expected and actual properties of 
+[expectation results](https://jasmine.github.io/api/5.7/global.html#ExpectationResult)
+
+
+## Internal improvements
+
+* Rewrote the build system to not use Grunt
+
+  Although Grunt has served Jasmine well over the years, it was keeping us tied
+  to an aging and increasingly questionable set of dev dependencies.
+
+* Updated to eslint 9
+* Removed mostly-unmaintained dev dependency 'temp'
+* Updated most other dev dependencies to latest versions
+* Fixed sass deprecation warning
+* Updated to Sauce Connect 5
+* Made stop-sauce-connect script more robust
+
+
+## Supported environments

+# Jasmine Core 5.9.0 Release Notes
+
+## Bug fixes
+
+* Avoid generating mock clock timer IDs that conflict with native ones 
+  * Fixes [#2068](https://github.com/jasmine/jasmine/issues/2068)
+  * Merges [#2069](https://github.com/jasmine/jasmine/pull/2069) from @atscott
+
+## Deprecations and changes to platform support
+
+* Node versions before 18.20.5 are no longer supported
+
+  Older 18.x versions might still work, but Jasmine is no longer tested in them
+  prior to release.
+* Document that the filename properties of suite and spec results are deprecated
+
+  These properties are incorrect in many configurations. They'll be removed in 
+  the next major release unless there is enough user interest in fixing them. 
+  See <https://github.com/jasmine/jasmine/issues/2065>.
+
+## Internal improvements
+
+* Extensive GlobalErrors refactoring
+  * Removed many of the error dispatching differences between browsers and Node
+  * Split into portable and platform-specific parts
+  * Converted to ES6 classes
+* Removed unnecessary errorWithStack helper
+
+  Jasmine no longer runs on platforms that create errors without stack traces.
+* Removed protections against user code redefining undefined
+
+  Jasmine no longer runs on platforms that allow redefining undefined.
+* Removed rimraf and shelljs dev dependencies
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment       | Supported versions      |
+|-------------------|-------------------------|
+| Node              | 18.20.5**, 20, 22, 24   |
+| Safari            | 15**, 16**, 17**        |
+| Chrome            | 138*                    |
+| Firefox           | 102**, 115**, 128, 140* |
+| Edge              | 138*                    |
+
+\* Evergreen browser. Each version of Jasmine is tested against the latest
+version available at release time.<br>
+\** Supported on a best-effort basis. Support for these versions may be dropped
+if it becomes impractical, and bugs affecting only these versions may not be
+treated as release blockers.
