Kanvaz went through a v5.3.0 bug-bounty pass that I once treated as the end of development. It wasn't. Since then there have been 47 published releases across the v6, v7, v8 and v9 lines: Smart Search, shared cards, real 3D model preview, Map View, Scratch Board, a Task Tracker, an AI Export plugin, and a lot of templates.
The latest published release is v9.7.0, with a Windows installer, a Linux AppImage, and macOS builds for both Apple Silicon and Intel. There's no fixed roadmap; updates land most weeks depending on what people report.
No subscription, no feature paywall, no telemetry. The only network calls are buttons you click yourself, like Check for Updates. Your files stay on your machine, and it stays free.
