Each product name is used once per organisation

Products are now the one level of your catalogue, and each product name can be used once in your organisation:

• No more near-duplicates. Creating or renaming a product to a name another active product already has — “CRM” next to “crm”, say — is refused, so leads, experts and coverage all point at one product.
• Archived names are free again. Archive a product and its name can be used for a new one.
• Platforms are gone. The hidden platform level some catalogues carried above their products has been removed. Your products, and the leads and experts linked to them, are unchanged.

In the demo workspace, the demo-data and reset summaries no longer list a “Catalogue platforms” count.
