Week of October 26, 2026
What shipped
- Updated vulnerable dependencies across the frontend, Python backend, Electron app, and export runtime, and hardened request routing, storage, parsing, and logging. Pull request #1002
- Released v0.9.12-beta with template hydration fixes, new landmark nova and signal templates, template image dimensions for generation, and updated image generation. Release
- Added an image provider test action in settings and onboarding that verifies the selected provider with current form values before saving, showing a preview on success and inline feedback for failures and timeouts. Pull request #1005
- Bundled Docker embedding models with a persistent FastEmbed cache, upgraded export to v1.0.51, and bumped the app to 0.9.12-beta. Pull request #989
- Fixed packaged fonts.json for custom template uploads by loading the catalog through Python's resource API, updating desktop bundling, and adding a Docker build check and packaging regression tests. Pull request #1006
- Fixed POST /api/v1/ppt/slide/edit returning HTTP 500 for template-backed presentations by reusing the template-aware layout resolver. Pull request #995
- Fixed Smart deck regeneration by adding an explicit POST reset before the confirmed Smart regeneration action so completed slides are not replayed. Pull request #993
- Fixed font CORS errors in sandboxed community previews by adding Access-Control-Allow-Origin: * only to public font responses. Pull request #991
- Fixed /status/{id} failing once a task has data by avoiding a deep copy of the session-loaded task model before rewriting result links. Pull request #988
- Fixed bundled template fonts in Windows Electron builds by installing the spaCy wheel, launching npm safely on Windows, and resolving bundled fonts in the frozen backend. Pull request #997
Why it matters
This week improves security across the frontend, backend, Electron app, and export runtime, and fixes several bugs that blocked template previews, slide edits, Smart deck regeneration, and font loading. The release adds template and image handling improvements while Docker now includes the embedding models needed at first request.
