+## [5.0.0](https://github.com/band-ai/band-sdk-python/compare/band-sdk-v4.0.0...band-sdk-v5.0.0) (2026-10-12)
+
+
+### ⚠ BREAKING CHANGES
+
+* ACP and Codex room replies require Band tools; remove retired fallback configuration.
+* the "sdk" Band MCP backend kind is removed; use kind="http" (with room_bound=True for per-room endpoints). BandMCPBackend drops its `server` field (use `local_server`), create_band_mcp_backend drops get_participant_handles/tool_result_hook, and the Claude SDK tool builders in band.integrations.claude_sdk.tools are removed.
+* Every SimpleAdapter turn is now judged by band-sdk-core's turn-outcome rule. Adapters that silently dropped a turn (langgraph, anthropic, gemini, google_adk, agno, letta, codex/ACP empty turns, copilot_sdk empty text) now report it and mark it FAILED. An undeclared custom tool counts as observe. settles_turn_reply, is_terminal_success and missing_reply_error are removed from band.runtime.tools. Custom SimpleAdapter subclasses are judged too: post adapter notices with send_notice and call tools.turn.settle(), because a send_message or deliver_reply post counts as the turn's reply. AgentToolsProtocol gains turn and send_notice.
+* the "sdk" Band MCP backend kind is removed; use kind="http" (with room_bound=True for per-room endpoints). BandMCPBackend drops its `server` field (use `local_server`), create_band_mcp_backend drops get_participant_handles/tool_result_hook, and the Claude SDK tool builders in band.integrations.claude_sdk.tools are removed.
