CrewAI 1.15.8 adds a WaitTool so crews can pause on long-running jobs
GitHub (crewAIInc/crewAI)·low signal
CrewAI released 1.15.8 on July 28 with a WaitTool that lets an agent explicitly pause while a long-running external job completes, instead of burning turns on polling loops or failing out. The release also fixes FileWriterTool writes and other rough edges in the file tool, and marks E2B_API_KEY as a required environment variable for E2B sandbox tools rather than failing obscurely at runtime.
