Notes

This is an experimental pre-release, not an official OpenToonz release. Back up production work before testing.

PDF loading requires pdftoppm.exe to be configured under Preferences > Encoder/Decoder. PDF export uses Qt directly and does not require Poppler.

Animated SVG export is appearance-based when raster frames are used. Embedded frames can substantially increase the SVG file size.

The session recorder remains disabled unless the user explicitly enables it.
