Removed all E2EE chat endpoints, crypto logic, and related API routes, transitioning chat to plain text storage and transport. Updated chat send/receive endpoints to use signed actions and enforce DM privacy settings. Cleaned up Swarm chat inbox, key management, and related debug endpoints. Updated user profile to support DM privacy, improved search for handle queries, and refactored conversation/message logic to support the new model. Migrated bot settings and privacy settings to new locations.
All user and post profile URLs have been updated from /[handle] to /u/[handle] for consistency. Added a redirect page for /posts/[id] to the canonical /u/[handle]/posts/[id] route. Deprecated and removed legacy scripts and documentation related to chat and federation endpoints. Push-based federation endpoints are now disabled in favor of real-time pull-based federation.
