Plans in Schematic now support versioning. When you make changes to a plan — whether to pricing, entitlements, or metadata — you can save those changes as a new version rather than mutating the plan in place. This means you can grandfather existing customers on their current terms while new subscribers get the updated plan automatically.

What's included:

• Plan drafts — all plan edits (name, pricing, entitlements, credits) are handled in a single draft flow with a save bar UI, consistent with how flag changes work

• Version creation — when saving changes, a new version is created and once you publish the draft you have the choice to migrate companies to the new version or leave them on the legacy plan

• Immediate migration — when creating a new version, you can migrate all or some existing subscribers to the new version immediately

• Versions dropdown — view all versions of a plan and which companies are on each

• Version selector in Manage Plan — defaults to the latest version; override per-company as needed
