Details on our Docker versioning and how to work with the images can be seen in ["Staying up-to-date with .NET Container Images"](https://blogs.msdn.microsoft.com/dotnet/2018/06/18/staying-up-to-date-with-net-container-images/). The following repos have been updated * [microsoft/dotnet](https://hub.docker.com/r/microsoft/dotnet) * [microsoft/dotnet-samples](https://hub.docker.com/r/microsoft/dotnet-samples) ### Azure AppServices * Deployment of .NET Core 2.1.5 to Azure App Services will begin on today, October 2, 2018. Deployment will proceed to additional regions and is expected to complete by the end of the week. ## .NET Core Lifecycle News .NET Core 2.0 went end-of-life yesterday, October 1, 2018 (see [announcement](https://github.com/dotnet/announcements/issues/86)). This means 2.0 is no longer eligible for updates and builds will no longer be provided. 2.1 was declared LTS last month (see [announcement](https://blogs.msdn.microsoft.com/dotnet/2018/08/21/net-core-august-2018-update/)) which began the end of life clock for 1.0 and 1.1. If remaining on the LTS channel is important to you, begin planning to migrate existing 1.0/1.1 applications to 2.1 before support for these channels ends on June 27, 2019. See [.NET Core Supported OS Lifecycle Policy](https://github.com/dotnet/core/blob/master/os-lifecycle-policy.md) to learn about Windows, macOS and Linux versions that are supported for each .NET Core release. ## Notable Changes in 2.1.5 This release includes a number of impactful fixes. Please see the [commit list](2.1.5-commits.md) for details. The commit list now includes details for ASP.NET Core and EntityFrameworkCore.
