 - Added language pair selection, glossary storage and fuzzy in-context suggestions.
 - Added local-only import/export pipeline with portal handoff integration.
 
+## 0.1.2 - 2026-09-03
+
+- Fixed parsing of multiple JS-like const/let/var translations in one file so
+  both locales are discovered (e.g. `const de = ...; const en = ...;`).
+- Added language handling sidebar with merged language-selection/workspace controls.
+- Kept glossary and output panels in the sticky right sidebar to reduce layout
+  drift while reviewing long translation lists.
+
 ## 0.1.1 - 2026-09-02
 
 - Improved parser robustness for JS-like translation files with multiple declarations.
