- control selection of relevant runs (needs langsmith release)
- see output of conditional edge function
- fix issue with conditional entry point not getting full state values as input
- fix bug when using at=END_OF_RUN together with interrupt_before
- fix bug when calling update_state after only node has run
- update some notebooks to new streaming format (ie. no __end__ node)
- Each iteration of the graph is one single iteration in Pregel (ie. no more "{node}:edges" nodes)
- .update_state() now acts exactly as one of the nodes in the graph (which can be chosen), which makes human-in-the-loop scenarios where you want to override the actions of a specific node a lot easier to build
- Graph/StateGraph.compile() now delegate adding nodes/edges/etc to dedicated methods that operate on the Pregel object, which is 90% of the way towards dynamic graphs where nodes and edges can be added during execution
- stream(stream_mode="values") yields thre current channel values whenever a channel is updated
- stream(stream_mode="updates") yields the update sent to each channel by each node
- this removes the __end__ value present at the end of each call to Graph/StateGraph/MessageGraph.stream(). To access the __end__ value either call .invoke() or stream(stream_mode="values")
- Add Pregel.get_state_history and .aget_state_history methods to get history iterator
- Update checkpointer base class with new list and get_tuple methods
- Rewrite in-memory checkpointer class to track history
- Rewrite sqlite and aiosqlite checkpointers to track history
- Add new tests for history tracking
- checkpoints are now copied before being mutated
- compiled graph and compiled state graph no longer need to override get_state/update_state
- pregel class now natively supports interrupt before/after
