+# Jasmine Core 5.13.0 Release Notes
+
+## Changes to supported environments
+
+Safari 26 is now supported on a best-effort basis.
+
+Due to the limited availability of Safari 18 and later on free CI services,
+Safari support in future jasmine-core versions will be limited to:
+
+* Best-effort support for the latest Safari version available on GitHub Actions,
+  which may change at any time.
+* Best-effort support for Safari 16 and 17 for as long as it remains practical.
+
+## New Features
+
+* New `extraItStackFrames` and `extraDescribeStackFrames` config options to fix
+  the filename properties of reporter events in configurations that wrap
+  `it`/`describe`, such as zone.js. The `filename` properties of reporter events
+  are no longer deprecated.
+* `jasmine.allOf` asymmetric equality tester
+  * Merges [#2087](https://github.com/jasmine/jasmine/issues/2083) from @jonahd-g
+  * Fixes [#2083](https://github.com/jasmine/jasmine/pull/2087)
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment | Supported versions             |
+|-------------|--------------------------------|
+| Node        | 18.20.5**, 20, 22, 24          |
+| Safari**    | 16, 17, 26.1                   |
+| Chrome      | 142*                           |
+| Firefox     | 102**, 115**, 128**, 140, 145* |
+| Edge        | 142*                           |
+
+\* 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.
