Changelog

v0.1.0 - 2026-06-25

Initial public release.

Added

• Java Swing JSON editor with tree navigation and typed value editing.
• File open, recent file, drag-and-drop, and command-line file loading.
• JSON path search and key filtering.
• Add, rename, duplicate, delete, and reorder actions for JSON nodes.
• Light and dark theme support.
• Maven build that produces a runnable shaded JAR.
• Lazy duplicate JSON key detection after load.
• Duplicate-key warning panel with dismiss action.
• Save confirmation when a loaded file contained duplicate keys.

Notes

• The editor loads the last value for duplicate JSON keys, matching the underlying parser behavior.
• Saving a file that originally contained duplicate keys rewrites the JSON and removes earlier duplicate values.
• The data/ directory is excluded from source control.
