+### 11.0.0-alpha6 - 2025-02-12
+* Add third argument to `FsCheckConfig.testFinished` containing information about the finished test.
+
 ### 11.0.0-alpha5 - 2025-01-13
 * Breaking Change: Add `isTestSkipped` parameter to `TestPrinters.beforeEach`, allowing to avoid printing skipped tests to the console, thanks @rynoV
   * Requires a coordinated upgrade to YoloDev.Expecto.TestSdk 0.15+ for use with Visual Studio, Rider, Ionide, dotnet test, or any other test runner that depends on the vstest adapter system
