Release Channels: stable and preview

SPG99 documentation uses release-channel labels. They help users immediately understand how much they can rely on a specific capability in production.

Stable

Stable is the main supported contract.

For the user, this means:

• the functionality is intended for normal operation;
• changes are accompanied by documentation and a changelog;
• breaking changes do not happen silently, without a visible transition period.

Preview

Preview is a feature or scenario that can already be tested, but its behavior may still change faster than usual.

In practice, this means:

• use preview only where you are ready for changes;
• for production-critical scenarios, rely primarily on stable sections;
• if a feature is important for your launch, align expectations with the platform team in advance.

How this works in practice

Changes do not go directly into the production environment: before reaching the main delivery, they are tested in test and pre-production stages. The user does not need to know how those stages are built — what matters is that the production environment receives already tested changes, and preview labels help separate the stable contract from early access.

How to read the documentation

• if a page is marked stable, treat it as the main working instruction;
• if a page is marked preview, treat it as a useful but more fluid scenario;
• if you are unsure which mode you need, always choose stable for production.
