Siemens Industrial Experience versioning and releases

Our Siemens Industrial Experience design team strives 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 This section describes our practices for new features and changes, deprecating and removing outdated features, and our long-term support for older versions.

Versioning

We use semantic versioning for our releases. Version numbers indicate the level of changes introduced by the release and follow the standard major, minor and patch format.

Release typeDetails
MajorContains 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.
MinorContains smaller features and changes. Updating requires no developer efforts. Minor versions can include components changing their status to deprecated. They are fully backward compatible.
PatchContains 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 stageSupport windowDetails
Active6 monthsReceive regular minor releases
Long-term support (LTS)6 monthsReceive 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.
