Why this signal matters
LangChain releases published langchain-core==1.7.0. This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Changes since langchain-core==1.6.13 release(core): 1.7.0 ( 41418 ) feat(core): emit tool-call-delta for streamed tool-call args ( 41257 ) Notes Tool-call args now stream as tool-call-delta slices instead of block-delta snapshots of the args so far. If you read raw stream events and their block-delta args mid-stream, read tool-call-delta instead. .tool calls.get() and .output are unchanged. To keep snapshots, pin langchain-core<1.7 . Since 1.6.13, iterating ChatModelStream.tool calls yields each call's new args slice, not a snapshot of the args so far.
