Current release · v0.7.0
What’s new in v0.7.0
JVN now uses a custom source-available attribution license. Engine source and utilities remain publicly available, and commercial games are permitted under the license. Developer tools and exports require acceptance of the current terms.
Games must show Made with JVN (engine version) in Settings, using the official JVN SVG logo. The engine supplies the visible credit; final package checks verify runtime files, branding, and license notices. You retain ownership of your independent game content.
License version 1.2 clarifies that concealing or modifying a binary does not waive applicable JVN obligations and describes formal enforcement procedures. Read the licensing and enforcement guide.
