v1.4.1

Changed

• Move Node canvas support to a dev-only canvas dependency and remove the package-level override so Fabric's optional peer dependency resolution is left to consumers.

Fixed

• Track image loading as an editor busy state so overlapping loads, transforms, exports, masks, and demo actions cannot mutate canvas state while a load is in progress.
• Make mask merging rollback-safe when the flattened image reload fails, without adding broken history entries.
• Preserve right and bottom image edges when merging masks over images whose displayed bounds end on partial pixels.
• Seal fractional export edge alpha during merge and export, including manual zoom states, so trailing rows or columns keep their own edge colors without resampling the full image.
• Composite genuinely transparent JPEG export areas against an explicit background because JPEG cannot encode alpha.
• Preserve the original container overflow snapshot across failed image-load rollbacks and disposal.
• Treat null, undefined, and invalid quality values as absent values instead of exporting at quality 0.
• Harden animation queue cancellation, image readiness listeners, pointer-event restoration, demo optional controls, and async history tests.
