Questions
Which item needs action first?
Pipecat 1.14.0, if you use the Perplexity service or Vertex AI's gemini-3.6-flash, which Vertex retires on November 19, 2026.
Which item can change behaviour without code changes? LangGraph 1.2.18. Handlers that were silently bypassed now run, and delta channels write snapshots ten times as often.
