Tool activity arrives as ordinary message chunks whose content blocks are tool_call and tool_result. When the LLM calls a tool, a chunk with a tool_call block is streamed; when the tool finishes, a chunk with a tool_result block follows; then token streaming resumes for the next LLM response.

Unknown extra keys are ignored. +- **`pass_user_info_to_mcp` sends the user dict as request metadata (`meta`),** not as a `user` tool argument. An MCP server that read a `user` argument must read `ctx.request_context.meta`. A warning is logged if the client's `call_tool` has no `meta` parameter. +- **New `ToolNode` options, off by default:** `max_result_chars`, `mcp_include` and `mcp_exclude`. `ToolNode` warns when a different callable replaces a tool of the same name, and accepts a generator of tools. +- **Factory tools bind their targets at creation:** `create_vertex_ai_search(datastore, model)`, `create_google_web_search(model)` and `create_fetch_url(allowed_hosts)`. The allow-list is checked on every redirect hop. The module-level `file_read`, `file_write` and `file_search` still work but warn; they are removed in 2.0, so use `create_file_tools`. +- **File tools:** overwrite is atomic and create is exclusive. The deny list adds `.git-credentials`, `*.tfstate`, `*.tfstate.*` and `*.tfvars`. Error text no longer leaks paths. +- **`PromptInjectionValidator` is less noisy and leaks less:** persona patterns are upper-case only, emoji and CJK no longer trip the special-character rule, hex digests are not flagged, and keywords match whole words. Error details carry `pattern_index` instead of the regex or a sample of the input. The production template validator no longer blocks `bypass`, `override`, `disable`, `token` or `free`, and its max length is 10000. +- **Client-visible error text shows only the exception type** for exceptions that are not 10xGraph's own (stream `ERROR` chunk `reason` and `state.error`). Logs keep the full text. `err.context` keeps the real values. +- **`@tool("name")` works as the name form, and `@tool` works on bound methods.** + +- **A `ToolNode` lists its MCP server's tools once.** The list is cached for the life of the node (`mcp_cache_tools=True`), which saves a connect, ping and list call per model call. Tools you add to the server later, and tools you remove, are not seen until you call `await tool_node.refresh_mcp_tools()`. If your server changes its tools while the process runs, build the node with `mcp_cache_tools=False` to list on every model call. A failed listing is never cached. +- **More `ToolNode` options for MCP, all optional:** `mcp_prefix`, `mcp_max_result_chars`, `mcp_max_description_chars`, `mcp_cache_tools` and `mcp_connect_timeout`. The connect timeout defaults to 30 seconds, so an MCP server that takes longer than that to accept a connection fails the call. Pass `mcp_connect_timeout=None` to wait without a limit.

At most 1000 background tasks can be pending; beyond that new ones are dropped (WARNING at most every 5 s, counter `background_task_manager.tasks_dropped`). Delivery is at-most-once with no retry. +- **Sync calls inside a running event loop raise `RuntimeError`.** `invoke()`, `stream()`, `stop()` and sync checkpointer methods such as `get_state()` name the async method to use. Async id factories (`AsyncIDGenerator`) now work. +- **A run refused while the graph is closing** sends a terminal error chunk with `data.code = "SERVICE_UNAVAILABLE"` and `retry_after_seconds`, and no `done` chunk. A WebSocket then closes with 1012. +- **Queued events are snapshots,** so consumers see the real `START` and `PROGRESS` events. LLM failures publish an `ERROR` event. Kafka and Redis publishers retry after a failed first start. The optional `publish_timeout` config key bounds one send and has no default. +- **A streaming LLM span ends when the stream ends.** The `LLM_CALL` `END` event is published after the last chunk, with `input_tokens`, `output_tokens`, `cache_read_tokens`, `cache_creation_tokens`, `reasoning_tokens`, `finish_reason` and `response_model`. A stream that fails publishes `ERROR` instead. The duration and token counts that tracing backends show for streaming calls now cover the whole stream, so dashboards and alerts built on those numbers will change. See [LLM span events](/docs/reference/python/publishers#llm-span-events). +- **Large `data["state"]` is replaced by a summary in published events.** When the state is longer than `state_snapshot_limit` JSON characters (publisher config, default 65536), consumers get `{"truncated": true, "bytes", "fields", "context_count", "context", ...}` instead of the full state. A consumer that reads message text from `data["state"]` needs a higher limit, or `0` or `None` to turn the summary off. See [Large state snapshots](/docs/reference/python/publishers#large-state-snapshots). +- **`RabbitMQPublisher` honors `publish_timeout`,** and `connection_timeout` (default 10 s) now also bounds opening the channel and declaring the exchange. If a broker accepts the connection but stalls there, that publish fails after 10 seconds, the connection is closed, and the next publish starts clean. +- **Swarm member names match case-insensitively,** and names that differ only in case raise `ValueError`. Supervisor `FINISH` matches only as a whole word. A RAG reranker error falls back to the retriever's order. + ### Runs and resume - **Multi-agent loop limits are per turn.** `max_rounds`, `max_iterations` and `max_attempts` reset on each new turn instead of being a lifetime budget per thread. - **Resume is checked.** A `resume_interrupt_id` that is not the pending interrupt's raises `InterruptMismatchError`, and a value that fails the interrupt's `response_schema` raises - `ResumeValidationError`. + `ResumeValidationError`. A `resume` sent to a thread that is not paused raises + `NothingToResumeError` (`INTERRUPT_003`), and a plain new message sent to a thread paused at + `interrupt()` raises `InterruptPendingError` (`INTERRUPT_004`).

Streaming runs also use + the tool ledger now. +- **Realtime tool calls are deduplicated per thread.** A call replayed after a reconnect, or repeated by a new session on the same thread, returns the recorded result and does not run the tool again. The key is the thread id, a hash of the tool name and arguments, and the provider call id. This needs a checkpointer on the session. `GeminiLiveClient` also takes `connect_timeout` (default 30 s), so a connect that hangs fails after 30 seconds. See [Tool call deduplication](/docs/reference/python/realtime#tool-call-deduplication). +- **New opt-in LLM limits, all off by default:** `stream_idle_timeout` (per agent, `set_default_stream_idle_timeout()` or `TENXGRAPH_LLM_STREAM_IDLE_TIMEOUT`; a stalled stream raises `LLMStreamIdleTimeoutError`) and the cross-process cap on `RetryConfig` (`distributed_max_concurrent_calls` and related fields; it fails open with a WARNING when Redis is down).
