+# Siemens Industrial Experience versioning and releases
+
+<p className="text-l-title">
+Our Siemens Industrial Experience design team strive to provide a stable and reliable system that's constantly evolving to meet your needs. This section describes our practices for new features and changes, deprecating and removing outdated features, and our long-term support for older versions. 
+</p>
+
+### Versioning
+
+We use [semantic versioning](https://semver.org/) for our releases. Version numbers indicate the level of changes introduced by the release and follow the standard major, minor and patch format.
+
+| Release type        | Details                                                     |
+|---------------------|-------------------------------------------------------------|
+| Major release       | Contains significant new features and changes, might include breaking changes. Updating requires some developer efforts and includes backward incompatible changes to APIs, file paths, component behavior and/or dependencies. Formerly deprecated components are removed when updating to a new major version. |
+| Minor release       | Contains smaller features and changes. Updating requires no developer efforts. Minor versions can include components changing their status to deprecated. They are fully backward compatible. |
+| Patch release       | Contains bug fixes. Updating requires no developer efforts. |
+
+### Release frequency
+
+We follow a time-based release schedule consisting of:
+- One major release every 6 months
+- 1-3 minor releases for each major release
+- Patch releases as hotfixes when necessary
+
+### Support policy
+
+All major releases receive support for approximately 12 months. We distinguish between two support stages for major releases:
+
+| Support stage           | Support window | Details                                       |
+|-------------------------|:--------------:|-----------------------------------------------|
+| Active                  | 6 months       | Receive regular minor releases                |
+| Long-term support (LTS) | 6 months       | Receive patch releases to fix critical issues |
+
+Our support policy applies to all components of the design system including the code base, Figma design kits and our documentation. 
+
+We recommend always following the active release. When a version moves from the active stage to the LTS stage, projects should start migrating to the new active major version. 
+
+### Supported versions
