 # v26.7.3, build 248 (2026-07-19 20:50 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 support for OpenDocument presentations (`.odp`) when attaching and reading presentation files.
 - 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.
 - Added AI-assisted editing and revision for assistants created with the Assistant Builder. Thanks, Nils Kruthoff (`nilskruthoff`), for this contribution.
 - Added options to view and edit the code of AI-generated assistants and to delete your own generated assistants. Thanks, Nils Kruthoff (`nilskruthoff`), for this contribution.
 - Added enterprise configuration options to hide the last changelog and vision panels on the welcome page. Thanks, Dominic Neuburg (`donework`), for the contribution.
 - 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 presentation imports so AI Studio can include speaker notes, slide comments, and presentation metadata in the extracted content.
 - Improved update guidance for Flatpak installations and added an enterprise option that lets organizations manage updates entirely through their IT department.
 - Improved secure API-key storage diagnostics on Linux. AI Studio now provides specific guidance when the default password collection is missing or locked, a password-manager prompt is dismissed, or no compatible Secret Service is available.
 - Improved the file dialogs to prevent opening multiple times when you click "Open" or "Save" multiple times in a row.
