为什么值得关注
LangGraph 1.2.18 introduces a default configuration change for DeltaChannel, triggering full snapshots every 100 updates rather than 1000. This change improves read performance on long threads at the cost of increased storage; the previous behavior can be preserved by setting snapshot frequency=1000. Additionally, the release enhances streaming support by allowing error handlers to recover across all paths while streaming failed task results, and ensuring the final checkpoint streams when a run is halted by an interrupt or recursion limit. Subgraph tag duplication has also been resolved, alongside dependency updates for opentelemetry-api and nbconvert.

- Evaluate storage impact of DeltaChannel snapshots taking place every 100 updates instead of 1000.
- Pass snapshot frequency=1000 in DeltaChannel configuration if legacy storage behavior is required.
