+# 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**        |

+| 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.
