v2.13.0

What's New

• Ruler-based page margins — Adjust page margins directly in the editor using the ruler, without opening a dialog.
• Custom collaboration worker providers — Configure your own worker implementation for real-time collaboration instead of relying on built-in providers.
• SDK file replacement — Replace DOCX files in open documents without reloading the editor, enabling workflow automation without UI interruption.
• Improved custom document controls — Better support for custom content control implementations with more granular state tracking.
• Simplified collaboration onboarding — Collaboration setup now provides clearer configuration and error messages to reduce integration friction.

Improvements

• Round-trip fidelity — Preserve exact inline offsets in bookmarks, multi-paragraph ranges, header and footer content controls, and paragraph property schema order. Heading levels 7–9 now round-trip correctly.
• Collaboration fidelity — DOCX documents maintain full formatting and metadata through v1-to-v2 room upgrades. Tracked changes and review decisions persist across collaboration sessions.
• Multi-column selection — Selection now stays within column bounds in multi-column layouts, and goal-x position is preserved across column-crossing navigation.
• Dirty state tracking — Document mutation tracking is now atomic and counts every committed mutation exactly once, preventing false dirty states from dry runs or no-op results.
• Performance — Footnote measure planes are retained without re-indexing, page metadata publication is deferred to reduce initial load, and field catalogs are reused for range deletion operations.
• Focus and accessibility — Selection-backed prompt cards now restore focus correctly across hide/show and scroll events. Theme playground modality is properly enforced with keyboard trapping.

Fixes

• Text replacement is now atomic and uncapped, handling large replacements without segmentation.
• Tab stop handling prevents hangs from non-positive default tab stops and normalizes invalid intervals.
• Toolbar escape key restores state after overflow menu reopens.
• Export now properly rejects v2 DOCX generation failures instead of silently succeeding.
• DOCX content is now available when collaboration reaches ready state.
• Heading search results are properly classified by level.
• Text selection stays inside document boundaries during findText operations.
• Content control creation and replacement through the Document API is now reliable under concurrent mutations.
