 ## Latest
+* Update Roslyn version to 7.0.0-preview.23456.2
+* Fixes regression where semantic colors for razor components appear as red
 * Update Roslyn version
   * Includes better support for .NET 8 and .NET Framework-targeting projects (PR: [#69616](https://github.com/dotnet/roslyn/pull/69616))
     * This should fix a number of reports where projects don't have full IntelliSense. .NET Framework projects on Windows should load without errors. .NET Framework targeting projects on Mac and Linux which would use Mono are still processed as if they are .NET Core projects and may not load correctly; support for Mono is coming in a future update.
