+# v26.7.3, build 247 (2026-07-19 17:58 UTC)
 - Added support for OpenAI GPT-5.6 Sol, Terra, and Luna; Anthropic Claude Fable 5 and Mythos 5; and Google Gemini 3 Flash, Gemini 3.1 Flash-Lite, Gemini 3.1 Pro, and Gemini 3.5 Flash.
 - Added a log viewer assistant that shows AI Studio log files in a read-only view with search, log filters, highlighting, and auto-refresh.
 - Added audio and video transcription for chats and assistants. AI Studio now prepares supported media locally, sends only normalized audio to the configured transcription provider, and attaches the resulting transcript instead of the original media.
