Release Notes

Bug Fixes

Text box editing: Fixed double-click to enter text box edit mode. The root cause was an infinite recursion in pane update cycles (show() → update() → show())
that crashed the event chain, plus a focus ordering issue where setFocus(textBox) was immediately undone by selectInlineElement() calling setFocus(null). Both
issues resolved in TextBoxPane, ImagePane, TablePane, and HyperlinkPane.
PDF image export: Images now render correctly in PDF exports. Previously, SVG and other non-JPEG/PNG formats silently fell back to placeholder rectangles. The
PDF generator now converts unsupported formats to PNG via canvas before embedding.
Table/text box formatting round-trip: Fixed formatting runs in table cells and text boxes being deserialized as single-character entries instead of ranges. A
bold word in a table cell now correctly survives export/import (previously only the first character retained formatting).
Formatting consistency: Fixed getFormattingAt() to merge overrides with defaults, preventing false run boundaries from inconsistent optional properties
(undefined vs 'normal').
Demo error: Removed reference to non-existent updateTableTools function that was causing console errors on every selection change.

Run-based formatting compression: Body text, table cells, and text boxes now all use a shared getCompressedRuns() method that only serializes formatting at
change boundaries, eliminating per-character redundancy.
Table cell default omission: Cell properties (borders, padding, background, font, alignment, spans) are omitted from export when they match table defaults. An
empty cell now serializes to just {} instead of ~250 bytes of redundant defaults.
Row/cell ID removal: Internal row and cell IDs are no longer exported since there are no cross-references in the file format. IDs are regenerated on import.
Old exports with IDs remain backward-compatible.
Row default omission: Row-level properties (height, minHeight, isHeader) omitted when matching defaults.
Net result: A 3×3 empty table dropped from ~15KB to ~2KB. Empty documents remain at ~455 bytes.

Logger utility: New centralized Logger with log, warn, and error methods. log/warn only output when enabled; error always outputs.
Editor option: enableLogging option on EditorOptions (default: false) and runtime editor.setLogging(enabled) API.
Consistent prefixing: All library logs use [pc-editor:ClassName] format for easy filtering. Demo logs use [Editor Event]/[Demo] prefixes.
API call tracing: 33 public PCEditor methods now log their invocations when logging is enabled.

Flexible spacer columns: All pane rows, button groups, and inline form groups include a zero-width ::after spacer that absorbs extra horizontal space, keeping
controls at their natural width when the sidebar is widened.
Minimum pane width: All panes share a consistent minimum width (--pc-pane-min-width: 220px).
Select dropdown max width: Combo dropdowns have a max width (--pc-pane-select-max-width: 200px) preventing infinite horizontal stretch.
Document Settings pane: Margin controls use a 5-column grid (label, edit, label, edit, stretch) with right-aligned colon labels. Margins apply on blur instead
of via an Apply button. Page Size and Orientation fields use a matching label-value grid layout.
Document Info pane: Converted to the same right-aligned colon label grid layout.

Unified repeating section API: createRepeatingSection() now detects when a table is being edited and automatically creates a row loop on the focused cell's
row, instead of requiring a separate API.
Table pane integration: Added "Row Loop" section to the Table pane with an array field input and Create Row Loop button.

Resizable sidebar: The side panel can now be dragged horizontally to test pane layout at different widths.
Logging toggle: View menu item to toggle console logging on/off (demo defaults to on).
Export round-trip test: View menu item opens a modal that exports the document, re-imports it, exports again, and displays byte sizes and difference to verify
serialization fidelity.
