2.0.0

Note: This release has breaking changes.

1. MediatorClient Refactoring

• Introduced a new MediatorClient.init factory for easier and safer instantiation, handling key agreement and signer resolution internally.
• All authentication and access token logic is now handled via a new AuthorizationProvider abstraction.
• Methods like sendMessage, fetchMessages, listInboxMessageIds, etc., no longer require explicit access tokens; tokens are managed automatically.
• WebSocket connection management is now handled via a new Connection class and a singleton ConnectionPool for concurrent connections.

2. AuthorizationProvider Abstraction

• Added AuthorizationProvider and AffinidiAuthorizationProvider for pluggable, extensible token management.
• Token refresh and challenge-response authentication are now encapsulated and reusable.
• All mediator flows (REST and WebSocket) now support authenticated mediators out of the box.

3. Connection & ConnectionPool

• New Connection class manages a single WebSocket connection and message stream.
• New ConnectionPool singleton manages multiple concurrent connections, subscriptions, and lifecycle.
• Important: All mediator clients must be registered with the pool before calling ConnectionPool.startConnections(). Clients added after startConnections() will not be managed.

4. API and Example Updates

• All examples and tests updated to use the new MediatorClient.init and AffinidiAuthorizationProvider.init flows.
• Removed legacy extension-based authentication methods.
• Simplified message sending, receiving, and inbox management APIs.

Migration Notes

• Replace direct MediatorClient constructors with MediatorClient.init.
• Use AffinidiAuthorizationProvider for Affinidi mediator authentication.
• Use ConnectionPool for managing multiple concurrent WebSocket connections.
• Remove any manual access token handling in your code.
