+### What's New in 1.13.0
+
+* Support for Cake files. (https://cakebuild.net/)
+* The language service now runs on Mono >= 5.2.0 when it is globally installed on macOS or Linux, resulting faster project load times.
+* If debugging is started when a launch.json is not present, picking ".NET Core" generates a launch.json dynamically that can correctly launch a .NET Core app without any additional changes.
+* Better reliability loading projects when Visual Studio 2017 (Windows) or Mono >= 5.2.0 (macOS/Linux) is installed.
+* Fixed issues with non-C# projects (such as F#) being treated as C# projects.
+* Addressed bugs when renaming files.
+* New options for controlling the display of the references and test CodeLens:
+  * `csharp.referencesCodeLens.enabled`
+  * `csharp.testsCodeLens.enabled`
+* Fixed problems with running/debugging xUnit 2.3.0 or NUnit tests.
+* Many other bug fixes!
