- Breaking change: Extension now formatted as export (and this is set to editor, including for callback)
- Breaking change: Locale now formatted as export - Breaking change: Moved out remaining modular i18n (imagelib) to own folder - Breaking change: Drop `executeAfterLoads` (and getJSPDF/getCanvg) - Breaking change: `RGBColor` must accept `new` - Breaking change: canvg - `stackBlurCanvasRGBA` must be set now by function (`setStackBlurCanvasRGBA`) rather than global; `canvg` now a named export - Breaking change: Avoid passing `canvg`/`buildCanvgCallback` to extensions (have them import) - Fix: i18nize imaglib more deeply - Fix: Positioning of Document Properties dialog (Fixes #246) - Fix (regression): PDF Export (Fixes #249) - Fix (regression): Add polyfill for `ChildNode`/`ParentNode` (and use further) - Fix (regression): Apply Babel universally to dependencies - Fix (regression): Ordering of `uaPrefix` function in `svgEditor.js` - Fix (regression): Embedded API - Fix (embedded editor): Fix backspace key in Firefox so it doesn't navigate out of frame - Fix: Alert if no exportWindow for PDF (e.g., if blocked) - Refactoring( RGBColor) `RGBColor` as class, without rebuilding constants, optimize string replacement, move methods to prototype, use templates and object literals, use `Object.keys` - Refactoring (canvg) Use classes more internally, use shorthand objects; array extras, return to lazy-loading - Refactoring: Use Promises in place of `$.getScript`; always return Promises in case deciding to await resolving - Refactoring: Avoid importing `RGBColor` into `svgutils.js` (jsPDF imports it itself) - Refactoring: Arrow functions, destructuring, shorter property references - Refactoring: Fix `lang` and `dir` for locales (though not in use currently anyways) - Refactoring: Provide path config for canvg, jspdf
