## Full changelogs

* [Docker and self-hosted changes from `v0.9.0-beta` through `v0.9.3-beta`](https://github.com/presenton/presenton/compare/v0.9.0-beta...v0.9.3-beta)

## 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

<Warning>
  Cloud v3 and self-hosted v1 are separate APIs. Do not copy a Cloud request into a self-hosted integration without adapting its URL, authentication, endpoint, and schema.
</Warning>

## Before upgrading

1. Back up `/app_data`.
2. Pin `ghcr.io/presenton/presenton:v0.9.3-beta` or an intentionally selected image digest.
3. Re-test sign-in and user access, Template V2 creation, presentation generation, editing, image uploads, streaming, and both export formats.
4. Re-run a representative UI, API, export, and MCP workflow after the upgrade.
