+### ✨ Highlights
+
+- **Redesigned Tables listings & Search:** Introduced a dedicated search field
+  for user tables and reworked the table listing UI to display additional
+  metadata directly on the table cards.
+- **Updated OEO Viewer & Entity Pages:** Reorganized the OEO Viewer layout for
+  better hierarchy and mobile responsiveness. Added a language toggle for
+  English/German synonyms, automatic entity-type detection, and an updated Graph
+  View widget that supports graph comparisons.
+- **Scenario Comparison App (Prototype) Update:** Refactored the quantitative
+  scenario comparison prototype to work with the updated OEKG and OEO. The app
+  now uses E-Charts as its graph library.
+- **Automated Metadata Syncing:** The metadata API now synchronizes the
+  documented data schema in the metadata with the actual table schema available
+  in the database.
+- **Bug Fixes & General Improvements:** Fixed an issue in the oemetaBuilder tool
+  that removed specific references on save, corrected the Reviewer & Contributor
+  progress calculations to account for empty fields, and patched an OEO loading
+  bug related to version 2.12.0.
