 # v26.7.3, build 245 (2026-07-xx xx:xx 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.
 - Improved the "My Tasks Assistant": you can now provide one or more documents in addition to text or use documents alone when asking to identify tasks.
 - Improved update guidance for Flatpak installations and added an enterprise option that lets organizations manage updates entirely through their IT department.
 - Fixed an issue that could leave AI Studio unresponsive after waking the computer from sleep.
