[Unreleased]

[0.2.0] - 2026-03-24

Added

  • A2UI.Agent behaviour and use A2UI.Agent macro for building agents with minimal boilerplate
  • A2UI.Agent.send_message/2 and send_messages/2 helpers for agent-to-client messaging
  • A2UI.Connection opaque handle for transport-agnostic client connections
  • SSE + JSON-RPC HTTP transport: A2UI.Plug, A2UI.Plug.SSE, A2UI.Plug.JSONRPC, A2UI.Plug.ConnectionRegistry
  • A2UI.Transport.SSE client-side transport for connecting to SSE endpoints
  • A2A protocol transport binding: A2UI.A2A server adapter, A2UI.Transport.A2A client transport (optional dep on :a2a ~> 0.2)
  • A2UI.Protocol.Messages.Error message type for client-to-server error feedback
  • A2UI.Catalog module for compile-time component type validation against catalog schemas

Changed

  • Agents track connections as %{id => Connection.t()} map instead of MapSet of PIDs (breaking for custom agent implementations that relied on the internal connection tracking format)
  • Demo agent refactored to use A2UI.Agent behaviour

Fixed

  • Form handling: added missing phx-submit attribute
  • Catalog validation: accept custom component_modules in validation
