LangGraph v0.6

We’re excited to announce the release of LangGraph v0.6.0, another significant step toward our v1.0 milestone. This release emphasizes providing a cleaner, more intuitive developer experience for building agentic workflows. Below we’ll cover the headline improvements and minor changes.

🚀 New Context API: Simplified Runtime Context Injection

The biggest improvement in v0.6 is the introduction of the new Context API, which makes it easier to pass run-scoped context in an intuitive and type safe way.

This pattern replaces the previously recommended pattern of injecting run-scoped context into config['configurable'].

Before (v0.5):

from langchain_core.runnables import RunnableConfig
from langgraph.graph import StateGraph

def node(state: State, config: RunnableConfig):

### verbose .get() access pattern for nested dicts    
    user_id = config.get("configurable", {}).get("user_id")
    db_conn = config.get("configurable", {}).get("db_connection")
    ...

builder = StateGraph(state_schema=State, config_schema=Config)

### add nodes, edges, compile the graph...
### nested runtime context passed to config's configurable key
result = graph.invoke(
    {'input': 'abc'}, 
    config={'configurable': {'user_id': '123', 'db_connection': 'conn_mock'}}
)

After (v0.6):

from dataclasses import dataclass

from langgraph.graph import StateGraph
from langgraph.runtime import Runtime

@​dataclass
class Context:
    """Context schema defined by the developer."""    
    user_id: str    
    db_connection: str
    
def node(state: State, runtime: Runtime[Context]):

### type safe access to context attributes    
    user_id = runtime.context.user_id
    db_conn = runtime.context.db_connection
    ...

builder = StateGraph(state_schema=State, context_schema=Context)

### add nodes, edges, compile the graph...
### top level context arg is typed as Context for autocomplete and type checking
result = graph.invoke(
    {'input': 'abc'},
    context=Context(user_id='123', db_conn='conn_mock')
)

The Runtime class provides a single interface for accessing information like:

• context: static data passed at the start of a run
• store: storage mechanism for long term memories
• stream_writer: custom function for writing to the graph’s output stream
• for functional API users, previous is also available: the previous return value for the given thread

Now, instead of injecting all of the above as separate parameters to node functions,
developers can access them all through a single runtime parameter.

Migration Path

• config_schema is deprecated in favor of context_schema, and will be removed in v2.0.0
• The new API maintains backward compatibility for existing code
• Gradual migration is supported with deprecation warnings for config_schema
• get_config_jsonschema is deprecated in favor of get_context_jsonschema (though this is generally only used for graph introspection and not by most langgraph users)

🔀 Dynamic model & tool selection

create_react_agent can now dynamically choose both the model and tools at runtime using a custom context object:

from langgraph.prebuilt import create_react_agent

@​dataclass
class CustomContext:
    provider: Literal["anthropic", "openai"]
    tools: list[str]

def select_model(state, Runtime[Context]):
    model = {
        "openai": openai_model,
        "anthropic": anthropic_model,
    }[runtime.context.provider]

    selected_tools = [
        tool for tool in [weather, compass]
        if tool.name in runtime.context.tools
    ]

    return model.bind_tools(selected_tools)

agent = create_react_agent(
	select_model, 

### Initialize the agent with all known tools
	tools=[weather, compass]
)

Then invoke the agent with your desired settings:

agent.invoke(
    some_input,
    context=CustomContext(provider="openai", tools=["compass"])
)

Now agents can flexibly adapt their behavior based on runtime context.

🏗️ Durability Mode Support

LangGraph v0.6 introduces a new durability ****argument that gives you fine-grained control over persistence behavior. This provides finer grained control than its predecessor, checkpoint_during.

This was predated

• Choose between three durability modes:
  • "exit" - Save checkpoint only when the graph exits
    • equivalent to checkpoint_during=False
    • Least durable, fastest
  • "async" - Save checkpoint asynchronously while next step executes
    • equivalent to checkpoint_during=True
    • Moderately durable, mid speed
  • "sync" - Save checkpoint synchronously before next step
    • New!
    • Highly durable, slowest

Migration Path

checkpoint_during is now deprecated in favor of the new durability argument. Backwards compatibility will be maintained until v2.0.0.

🛡️ Enhanced Type Safety and Validation

In an effort to make graph building easier for developers, we’ve enhanced the type safety of the
LangGraph APIs.

LangGraph’s StateGraph and Pregel interfaces are now generic over a graph’s:

• state_schema
• context_schema
• input_schema
• output_schema

This means that:

• Node signatures are type checked at graph creation time
• Input to invoke / stream is type checked against the relevant schema
• context available via the aforementioned Runtime class matches the context_schema

🔧 A Refined Interrupt Interface

In preparation for v1.0, we’ve made a few changes to the Interrupt interface.
Interrupts now have two attributes:

• id - a unique identifier for the interrupt
• value - the interrupt value

In v0.6, we’ve removed the following attributes from the Interrupt class:

• when - this was always "during" and offered no practical value
• resumable - functionally, this is always True
• ns - this information is now stored in a condensed format in the id attribute
• interrupt_id has been deprecated in favor of id, but is still usable for backward compatibility

🔒 Solidified Public API Surface

Gearing up for v1.0, we’ve solidified what’s public vs. private in the LangGraph API.
We’ve also deprecated some old import paths that have supported backports for ~1 year.

These changes make it easier to maintain a higher quality public API
and reduce the surface area for potential breaking changes.

The following table summarizes the changes:

Old Import	New Import	Status
from langgraph.pregel.types import ...	from langgraph.types import ...	⚠️ Deprecated - Will be removed in V2
from langgraph.constants import Send	from langgraph.types import Send	⚠️ Deprecated - Will be removed in V2
from langgraph.constants import Interrupt	from langgraph.types import Interrupt	⚠️ Deprecated - Will be removed in V2
from langgraph.channels import <ErrorClass>	from langgraph.errors import <ErrorClass>	❌ Removed - All errors now centralized in langgraph.errors
from langgraph.constants import TAG_NOSTREAM_ALT	from langgraph.constants import NOSTREAM	❌ Removed - Deprecated constant removed

🎯 Looking Toward v1.0

LangGraph v0.6 represents our final major changes before the stable v1.0 release.
We anticipate adhering strictly to SemVer post v1.0, leaning into a promise of stability and predictability.

v0.5.0

LangGraph 0.5 – the “Getting-Ready-for-1.0” release 🎉

TL;DR – 0.5 is not a radical rewrite, but a scrub-down and tune-up of the LangGraph core.

APIs are a little stricter, you have more control over streaming, checkpoints are lighter, etc. 99 % of users can upgrade with nothing more than a pip install --upgrade langgraph==0.5.*.

---

Why 0.5?

The team’s next big milestone is a 1.0 release in a few months.

To get there we needed to:

• lock in the few API surfaces that still felt “fuzzy”
• prune internal code paths that made distributed execution harder
• land long-queued performance work

0.5 is that housekeeping release.

---

Headline changes

1. A leaner, stricter StateGraph

1. state_schema is now mandatory.

   “Untyped” graphs were never shown in the docs and produced surprising runtime errors. Requiring an explicit schema fixes that class of bugs and improves static analysis.

2. input/output → input_schema/output_schema

   The old names still work but raise a deprecation warning.

   graph = StateGraph(
       state_schema=MyState,
       input_schema=UserQuery,
       output_schema=AssistantResponse,
   )

3. New NodeBuilder utility

   A simpler, declarative way to create nodes and attach them to channels. The old Channel.subscribe_to helper keeps working but will be removed in 1.0.

2. Smarter streaming modes

• stream_mode="debug" is now an alias for the pair["tasks", "checkpoints"]. You can now turn them on individually:

graph.stream(stream_mode="tasks")        # only task-level updates
graph.stream(stream_mode="checkpoints")  # only checkpoint deltas

This makes it cheaper to subscribe only to the information you need.

3. Checkpointing overhaul

• Smaller blobs & faster restores
  Redundant keys have been dropped and per-task writes are stored directly.
• Seamless migrations
  Legacy “pending _sends” data is auto-migrated the first time it is loaded. Custom checkpointers continue to work unchanged.

4. Better serialization

• JsonPlusSerializer now handles NumPy arrays stored in your state (including Fortran-ordered ones) without falling back to pickle.

---

Minor breaking changes you might notice

1. state_schema required – add it if you were passing only input and output schemas instead (very rare).
2. input / output renaming – rename to input_schema / output_schema.
3. Subclassing internals – if you subclassed PregelNode and Runnable, drop the latter.

Nothing else should require code changes.

---

How to upgrade

pip install -U "langgraph>=0.5"

If you maintain a plugin / custom checkpointer, run your test suite once; the public interfaces are untouched.

---

What’s next?

We’re hard at work on LangGraph 1.0, chime in here with any comments, feedback or questions, we want to hear from everyone.
