 ---------------------------------------
 As was outlined in the ["Changes to project.json" blog post](https://blogs.msdn.microsoft.com/dotnet/2016/05/23/changes-to-project-json/), we have started work to move away from project.json to csproj and MSBuild. All the new `latest` releases from this repo (from `rel/1.0.0` branch) are MSBuild-enabled tools.
 
-The current official release of the csproj-enabled CLI tools is **CLI Preview 4**. 
+The current official release of the csproj-enabled CLI tools is **CLI RC 4**. 
 
 There are a couple of things to keep in mind:
 
-* Preview 4 CLI bits are still **in development** so some rough edges are to be expected. 
-* Preview 4 bits **do not support** project.json so you will have to either keep Preview 2 tools around or migrate your project or add a global.json file to your project to target preview2. You can find more information on this using the [project.json to csproj instructions](https://github.com/dotnet/cli/blob/rel/1.0.0/Documentation/ProjectJsonToCSProj.md). 
-* Preview 4 refers to the **CLI tools only** and does not cover Visual Studio, VS Code or Visual Studio for Mac.
