+# Changelog
+
+## 0.1.2 (2026-03-18)
+
+### Bug Fixes
+- Fix `ResponseNotRead` crash when SSE streaming encounters HTTP 503 error
+
+### Features
+- `listen()` now accepts optional `status` parameter to filter intents by lifecycle status
+- Default SSE stream excludes terminal statuses (COMPLETED, FAILED, CANCELED, TIMED_OUT) — agents no longer receive zombie intents
+
+## 0.1.1 (2026-03-13)
+
+- Initial alpha release with full AXME API coverage (96 methods)
+- SSE streaming (`listen`, `observe`, `wait_for`)
+- Scenario API (`apply_scenario`, `validate_scenario`)
+- MCP protocol support (`mcp_initialize`, `mcp_list_tools`, `mcp_call_tool`)
+- Intent lifecycle, inbox, webhooks, admin APIs
+- Zero external dependencies beyond httpx
