0.3.0 (2026-04-23)¶

Social login with OAuth, AI description generation, and unified smart chat.

✨ Features¶

OAuth / Social Login with Google: provider-agnostic architecture (IOAuthProvider + OAuthProviderFactory) with Google OAuth 2.0 / OpenID Connect as the first provider. Extensible for future providers (GitHub, Microsoft) by adding only an adapter class.
OAuth managed as an integration from the admin panel (enable/disable).
Automatic account linking: if the OAuth email matches an existing account, the provider is linked automatically.
New OAuth users get automatic account creation with FREE subscription.
MFA bypass for OAuth logins — 5-day JWT issued directly.
CSRF protection via server-side state tokens (10-minute TTL, MongoDB auto-cleanup).
ID token validation (signature, issuer, audience, expiration) for OpenID Connect.
Rate limiting on OAuth callback endpoint.
Audit logging for all OAuth events (login success/failure, account linking).
Profile page shows linked OAuth providers with link date.
Language selector on login and register pages (top-right corner).
App version displayed on the login page.
MFA banner hidden for OAuth sessions (MFA does not apply to social logins).
Free-form AI description generation: generates structured Markdown descriptions for existing diagrams, with the ability to refine the generated description.
Unified chat with automatic intent detection: the AI chat automatically detects whether the user wants to converse, generate a new diagram, or improve the existing one — no need to manually select a mode.
