v2.0.0-RC.6

v2.0.0-RC.6

One-time manual install required

This is the first RuntimeViewer build to include Sparkle-based auto-updates.
Users on v2.0.0-RC.3 or any earlier v2.x beta/RC must download and install
this release manually — there is no auto-update path from a Sparkle-less
build. Every release after RC.6 will be delivered through the in-app
update flow.
