Anthropic SDK v0.119.0
July 24, 2026
v0.119.0, released on 2026-07-23, adds a new API stop reason, `model_context_window_exceeded`, and fixes agent toolset read/edit handling for binary files. The new stop reason makes context-limit failures explicit, while the binary-file fix improves tool reliability when agents inspect or modify non-text content.
