one of the features i'm most excited about in our upcoming langgraph release is delta channels! the langgraph runtime lets you "checkpoint" agent progress at every step (model call, tool call, hooks). the problem, though, is that checkpoints bloat quickly when context is long! delta channel mitigates this with diff based storage from checkpoint to checkpoint. with delta channels, you still have a full history of agent progress, the only diff (haha get it) is the storage format. in-depth blog coming soon, but in the meantime, try it out and lmk what you think! https://docs.langchain.com/oss/python/langgraph/pregel#deltachannel-beta
