Month: 2025-10 — Summary: Delivered a focused set of features, reliability fixes, and release-readiness improvements across xwiki-platform and xwiki-rendering, translating into tangible business value: more predictable deployments, improved macro and editing UX, and more robust document rendering. Key features delivered include Solr standalone WAR packaging support; macro config UI improvements to indicate deprecated parameters; dedicated per-version pages in the Repository for each extension; and an upgrade of Syntax highlighting to 4.10. Major bugs fixed include: BaseObject#set metadata dirty flag behavior corrected to prevent unintended metadata dirtiness in owner documents; TOC notification links redirect to the correct resource; Include macro execution when no reference is specified; Display macro execution when no reference is specified; LiveData editing edge-cases with ':' handled; and warnings when objects exist in the Object editor. The work also covered release-readiness tasks such as inter-project dependency alignment on master, and release branch preparation, plus inter-repo collaboration across xwiki-platform and xwiki-rendering. Technologies and skills demonstrated include Maven release plugin usage, Weblate translations integration, Solr/WAR packaging considerations, WYSIWYG editor enhancements, and front-end link protection improvements.
