Steeltoe Support Versions
This document shows all versions of Steeltoe and their support lifecycle.
Steeltoe follows the VMware Tanzu OSS support policy for critical bugs and security issues.
-
Major versions will be supported for at least 3 years from the release date (but you must run a supported minor version).
-
Minor versions will be supported for at least 12 months.
The supported .NET Runtimes have been tested against the latest patch release of each version. We recommend running the latest minor with the latest patch release for each major version.
The following table shows the releases that are currently supported:
| Steeltoe Version | Release Date | End of Life Date | LTS | .NET Runtime Version |
|---|---|---|---|---|
| 3.2.x | May 26, 2022 | May 26, 2023 | No | .NET Core 3.1 (LTS), .NET 6 (LTS) |
| 3.x | August 24, 2020 | August 31, 2023 | No | .NET Core 3.1 (LTS) |

The Steeltoe team is very aware of the need for stability and backward compatibility across our major releases (i.e. 2.x and 3.x). Our goal is to keep backward compatibility across all minor and maintenance releases (e.g. 3.1.3 would still work with 3.1.2, 3.1.1, 3.1.0). For major releases, we utilize these releases to remove all deprecated code and make breaking changes when necessary for code optimization, enhancements, architecture changes, and redesign. We strive to keep all compatibility changes/breakages to major releases only. There is a rare chance that we might be forced to break compatibility in a minor release, but we will be sure to be clear of our reasons for doing so.
Steeltoe libraries depend on .NET runtimes, so we follow the .NET and .NET Core Support Policy. Once a runtime is out of support, Steeltoe will also discontinue support for running our libraries on those runtime versions.
