Known issues we've tracked

PRODUCT (2026-05-12): **LangGraph v1.2 shipped DeltaChannel beta** -- an alternative checkpointing primitive that stores **incremental state deltas** per node execution instead of full-state snapshots. LangChain published a 200-turn coding-agent benchmark showing **~41x storage reduction** vs the default full-state checkpointer, with no observed change in graph-resume fidelity. Material because (a) long-horizon agentic graphs (multi-hour research agents, coding agents on big codebases) had previously been blocked by checkpoint storage costs at production scale, (b) LangGraph Platform users hit storage caps fastest, so this directly impacts hosted-pricing economics, (c) DeltaChannel is opt-in -- existing graphs keep their current checkpoint behavior until you explicitly switch. Beta gating expected through Q2 2026.
