API compatibility
The self-hosted API remains under/api/v1/. The release adds blank-presentation endpoints and introduces multi-user authentication, so integrations should re-test authentication and presentation-creation flows after upgrading. The current generation request supports:
- Prompt content, optional slide Markdown, and additional instructions
- Tone, verbosity, optional web search, slide count, and language controls
- Template selection, title and table-of-contents controls, and uploaded files
- PPTX or PDF export
- Optional webhook triggering
Before upgrading
- Back up
/app_data. - Pin
ghcr.io/presenton/presenton:v0.9.3-betaor an intentionally selected image digest. - Re-test sign-in and user access, Template V2 creation, presentation generation, editing, image uploads, streaming, and both export formats.
- Re-run a representative UI, API, export, and MCP workflow after the upgrade.
