[ 重大突破 ] v2.2.0

v2.2.0

2.2.0 (2026-06-04) ⚠ BREAKING CHANGES agents: LlmAgent default model changed from gemini-2.5-flash to gemini-3-flash-preview (a preview model), ahead of the 2026-10-16 gemini-2.5-flash shutdown. Agents without an explicit model= now run on the new preview default; set model="gemini-2.5-flash" to retain prior behavior. DEFAULT_LIVE_MODEL is unchanged. ( ad8b6c7 ) interactions: GenAI SDK v2.0.0 support renames the turn-based helpers in interactions_utils.py (e.g. convert_contents_to_turns → convert_contents_to_steps ) and moves from "turns" to "steps" terminology. Update any direct callers. ( da...
