Removed llms-full.txt
The llms-full.txt endpoint has been removed from Fern Docs sites. This file concatenated every page into a single document, but in practice it saw little use compared to llms.txt and individual .md page URLs. It also exceeded most model context windows and added significant serving overhead on every request.
If you previously relied on llms-full.txt, use llms.txt to discover page URLs and fetch individual pages as needed.
API catalog respects site authentication and RBAC
The /.well-known/api-catalog endpoint now mirrors what the viewer can see. Sites with authentication configured return an empty catalog to unauthenticated requests, and API references hidden through role-based access control no longer appear in the catalog.
