Quick take: this release is a reliability upgrade for people running real workflows.
What matters most:
• External secrets management is now much cleaner
• Routing/runtime got stronger (especially for threaded agent workflows)
• Several important reliability fixes landed (allowlists, queues, typing states, Telegram action handling, browser relay stability)
