## What's changed

### Smart generation and editing

* [Added Smart presentation generation and editing](https://github.com/presenton/presenton/pull/810), including streamed HTML slides, charts, assistant editing, community design selection, and Smart presentation metadata.
* [Added reasoning and token-usage metrics](https://github.com/presenton/presenton/pull/811) to Smart generation streams, with capability-aware reasoning for supported providers.

### Canvas and visual editing

* [Normalized content image fills](https://github.com/presenton/presenton/pull/795) so ordinary images use cover fitting without changing icons, SVGs, or clipped images.
* [Added alignment guides and snapping](https://github.com/presenton/presenton/pull/802) for single- and multi-element dragging.
* [Bundled canvas rendering assets locally](https://github.com/presenton/presenton/pull/803) for previews, PDF export, and custom-template flows.
* [Added editable KaTeX math elements](https://github.com/presenton/presenton/pull/804) across generation, rendering, importing, and editing.
* [Expanded the shape and arrow palette](https://github.com/presenton/presenton/pull/805) with grouped vector shapes, symbols, block arrows, and directional arrowheads.

### Templates and exports

* [Automated custom-template font resolution and preview preparation](https://github.com/presenton/presenton/pull/806).
* [Improved custom-template thumbnail navigation](https://github.com/presenton/presenton/pull/807) on responsive layouts.
* [Added repeatable Template V2 groups and the Editorial theme](https://github.com/presenton/presenton/pull/813).
* Improved Smart PDF and PPTX export rendering, chart snapshots, and slide-density handling.

## API and data compatibility

The self-hosted API remains under `/api/v1/`. This release extends presentation and chat responses with Smart-generation metadata, adds Smart-generation fields to the database, and introduces community-presentation proxy routes. Existing clients can ignore the additional Smart fields and the `generation_metrics` server-sent event when they do not use those features.

<Warning>
  Cloud v3 and self-hosted v1 are separate APIs. Adapt the URL, authentication, endpoint, and schema when moving a workflow between them.
</Warning>

## Before upgrading

1. Back up `/app_data` and any external database.
2. Pull `ghcr.io/presenton/presenton:latest`, or select an explicit version or image digest for a controlled rollout.
3. Re-test Smart and Standard generation, assistant editing, custom-template fonts, charts, math, and both export formats.
4. Confirm existing integrations tolerate the additional response fields and SSE event.
