> Hosting and API compatibility notes for Presenton v0.9.2-beta.

This documentation version follows the `0.9.2-beta` application version on the reviewed `presenton-3/main` branch. Work in this release focuses on Template V2 consolidation, generation and editing workflows, MCP access, export runtime maintenance, and the application interface.

## Changes since v0.9.1-beta

* Refactored presentation generation around Template V2 and removed obsolete template-processing code.
* Unified template identification across generation and rendering.
* Removed obsolete PDF/PPTX slide-processing endpoints while retaining PPTX and PDF presentation export.
* Added a restricted MCP workflow for synchronous generation, asynchronous generation, and task-status polling.
* Added bearer-token verification for MCP when application authentication is configured.
* Kept MCP disabled in the Electron desktop app to avoid its authentication conflicts.
* Improved chat and presentation-memory handling, slide UI editing, autosave, and image-editor behavior.
* Updated the presentation export runtime to `v0.4.2`.
* Updated the dashboard and presentation-management interface.

## API compatibility

The self-hosted API remains under `/api/v1/`, but internal cleanup removed obsolete routes and changed implementation details. 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:v0.9.2-beta` or an intentionally selected image digest.
3. Re-test Template V2 creation, presentation generation, editing, MCP authentication, and both export formats.
4. Re-run a representative UI, API, export, and MCP workflow after the upgrade.
