The .NET Core SDK 3.0.100 Preview 5 includes .NET Core 3.0 Runtime so downloading the runtime packages separately is not needed when installing the SDK. After installing the .NET Core SDK 3.0.100 preview, the following command will show that you're running version `3.0.100-preview5-011568` of the tools.

`dotnet --version`

Your feedback is important and appreciated. We've created an issue at [dotnet/core #2685](https://github.com/dotnet/core/issues/2685) for your questions and comments.

## Lifecycle News

### Ubuntu 14.04 reached the end of standard support 

Ubuntu 14.04 reached the end of its [Standard Support lifecycle](https://wiki.ubuntu.com/Releases) April 2019. As described in [.NET Core OS Lifecycle Policy](https://github.com/dotnet/core/blob/master/os-lifecycle-policy.md), we will no longer test .NET Core on this version or produce updates for the OS version.

### .NET Core LTS

Our plans call for the next LTS release of .NET Core toward the end of 2019. We are also working on a long term release roadmap which will enable you to better plan for updates and understand the LTS release cycle. An introduction to the roadmap can be seen in the [.NET 5 blog post][dotnet5-blog]
