Two entries changed. The findings do not show which model names they belong to.\n\n- One entry, the one with `hard_limit` 190000 and `auto_permission_mode` \"unavailable\", now has `voice_model: \"claude-haiku-5-5\"`.\n\n- Another entry now has `supports_fast_mode` set to true.\n\n- That same entry's `min_claude_code_version`, the oldest Claude Code version that will offer the model, rose from \"2.1.251\" to \"2.1.290\".\n\n**Why**\n\nThese values decide which models are offered for voice and for fast mode. They also decide which Claude Code versions show the model at all. Versions older than 2.1.290 will no longer see the second entry.\n\n- Area: Models\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
