## .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://devblogs.microsoft.com/dotnet/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](../../../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
