Releasebot lists langgraph-sdk 0.4.14 with a source date of November 6, 2026, and says it was first seen on November 5. The aggregator's summary is direct: the release adds strict resume controls to run creation, streaming, and waiting, and expands StreamMode with tools and lifecycle events.
The notes, headed as changes since sdk==0.4.13, contain three lines. One is the release itself, sdk-py 0.4.14 (#9610). The other two are the features: strict_resume on runs.create, stream, and wait (#9599), and tools and lifecycle added to StreamMode (#9601). Those lines name the parameter and the methods. They do not say whether strict_resume defaults to on, which error a refused resume raises, or whether a rejected call leaves the thread unchanged. That detail is unknown from this listing.
Releasebot's entry for langgraph 1.2.20, dated November 5, 2026, says LangGraph adds unique IDs for task interrupts and strict resume validation that rejects stale answers. The 1.2.20 changes include giving each interrupt() in a task its own id (#9589) and a strict resume mode that refuses stale interrupt answers (#9574). The 0.4.14 note is not a second write-up of the library release.
It is also not the 0.4.12 change. That SDK release, listed November 3, 2026, removed fairness_weight from PrioritySettings and fixed rejoining a run stream that closes before the run ends. The version between them, 0.4.13 on November 5, added cancel_reason to Run and a select option on threads.get_state and get_history. None of those items are in the 0.4.14 notes.
Read the 0.4.14 and 1.2.20 entries on the Releasebot LangGraph updates page before you pass strict_resume into runs.create, stream, or wait. This listing does not document how strict_resume behaves, and it is not a StreamMode reference page.
