5 Commits • 4 Features
Feb 1, 2026February 2026: Focused on stabilizing local Solr workflows, enhancing content management UX, localization accuracy, and repository hygiene. Delivered dev-friendly Solr health checks with automatic rebuild/reindex, improved troubleshooting, and a modular rebuild script. Introduced UI improvements for subject management (pencil icon and edit button in subject tags). Fixed container reliability by making the Solr start script executable in Docker. Improved localization for Hindi ('See all works') and strengthened build hygiene with beads JSONL handling and ignore rules. These changes reduce time-to-value for developers, improve search quality in local/dev environments, and tighten overall build and release readiness.
