There is no status page (nothing is hosted), no published deprecation policy, no SLA and no Sunset/Deprecation header surface. The only formal migration document is the Gemini V5.2+ upgrade guide. The corporate lifecycle matters here too: the homepage (2025) states "Ultraleap is joining ROLI", and several linked hosts (support.ultraleap.com, www.ultraleap.com/licensing/, developer.leapmotion.com) no longer resolve or 404, so parts of the published surface are already decaying. versioning: scheme: software-release generations: - name: Orion major: V4 status: superseded note: Legacy Leap Motion tracking; shipped the LeapJS WebSocket protocol. - name: Gemini major: V5 status: superseded note: Ultraleap Hand Tracking Software 5.x; LeapC + engine plugins.
