• Added filtering capability to exclude subgraphs that have disabled checkpointing
• Broadened the type hint for store values to be more flexible

Detailed Changes

langgraph.pregel.Pregel

• Added new optional namespace parameter to get_subgraphs and aget_subgraphs methods to filter subgraphs by name
• Added logic to exclude subgraphs that have disabled checkpointing (checkpointer is False) from being considered
• Optimized get_state, aget_state, get_state_history, aget_state_history, update_state, and aupdate_state methods to use the new namespace filtering capability, improving performance when working with nested subgraphs
• Improved handling of recursive subgraph queries when using namespaces

BaseStore

• Changed the type definition of store values (V) from dict[str, Any] to Any, allowing for more flexible value storage in stores
