Boongle 1.8 Pro

Boongle 1.8 Pro shipped and is now available in Boongle IDE. It is a substantial step up in intelligence and behavior over Boongle 1.8 Flash — better at sustained work on long-running tasks, more reliable on complex instructions, and tuned for multi-step agent sessions — with BoongleBench scores above Flash but still below frontier API models such as Claude Fable 5.1.
