Dec 1, 2025

December 2025 was focused on navigation improvements, reliability, and API modernization across multiple repos (nextcloud/text, nextcloud/collectives, nextcloud/viewer, and ueberdosis/tiptap). Key navigation features include persistent editor headings via useEditorHeadings, a visible outline, and a right-side Table of Contents to greatly improve content discovery. The Markdown/Table editing path was hardened: refactored rowToMarkdown and normalizeCells, dropped headerless table parsing to avoid unintended markdown changes, and updated CSS to improve cell selection visibility and editor layout. Viewer-facing updates upgraded dependencies to @nextcloud/files v4 beta, migrated WebDAV usage to the new API, and aligned viewerAction with the updated API. Collectives gained robust Markdown import workflows, progress feedback, README-as-index support, and backlinks/sidebar integration. CI/test reliability and accessibility were improved: tests moved to example.org to avoid rate limits, and a temporary server pin stabilized Cypress tests with a planned revert.
