+# Migrating to ACP Python SDK 0.8
+
+ACP 0.8 keeps the 0.7 public surface but aligns the SDK with the latest ACP schema and tightens a few runtime behaviors. Most teams only need to review the updated schema and terminal helpers. This guide calls out the changes that can affect downstream agents, clients, and tests.
+
+## 1. ACP schema bumped to 0.10.8
+
+- Regenerate any internal copies of ACP schema-derived artifacts against 0.10.8.
+- If you vendor schema types, run `make gen-all` or your equivalent pipeline.
+- Helper types now include `SessionInfoUpdate` in the `SessionUpdate` union, so downstream code that exhaustively matches update variants should include it.
+
+## 2. `TerminalHandle` removal
+
+`TerminalHandle` is no longer part of the public API. If you referenced it directly, switch to the request/response models and terminal IDs returned by `CreateTerminalRequest`/`CreateTerminalResponse`.
+
+Typical adjustment:
+
+```python
+# Before (0.7.x)
+handle = await conn.create_terminal(...)
+await conn.terminal_output(session_id=..., terminal_id=handle.id)
+
+# After (0.8.x)
+resp = await conn.create_terminal(...)
+await conn.terminal_output(session_id=..., terminal_id=resp.terminal_id)
+```
+
+## 3. Larger default stdio buffer limits
+
+The default stdio reader limit is now 50MB to support multimodal payloads. If you run in memory-constrained environments, explicitly set `stdio_buffer_limit_bytes` when calling `run_agent`.
+
+```python
+await run_agent(agent, stdio_buffer_limit_bytes=2 * 1024 * 1024)
+```
+
+## 4. Documentation and quickstart updates
+
+Docs and settings examples have been refreshed for ACP 0.10.8. If you maintain internal onboarding material, sync it with the latest docs in `docs/`.
