Package publication and platform verification are separate claims. The candidate native installation requires Linux x86_64 with glibc 2.39 or later (ELF requirement measured; consumer verification pending); see Install mx and release metadata. macOS and Windows are not verified by this route.
The three tiers
- Shipped: released. You can install it from a registry at the version shown.
- Preview: an early implementation with stated limits. It may have a downloadable build; that does not establish a stable API or support for every platform. A course may teach it.
- Planned: recorded in a program's plan, not built. A Planned page has no runnable example.
The fifteen public @fiberfx modules are Shipped: 4.0.0 was released on npm on 2026-11-05, and latest is 4.0.0 for each. The day before, npm still answered "not found" for them. The previous major, 3.x, stays published on npm under the earlier scope, @mercury-fx/* (@mercury-fx/ui is at 3.0.0 there). mx, live_mercury and the private modules are still Previews.

The mx workspace names eighteen modules: fifteen public, three private. The table lists seventeen of them. The eighteenth is the state package that Hypergraph succeeds: private, retired and not published, and this site doesn't teach it.
How versions move
The @fiberfx modules release together at one version. 4.0.0 is a major release because every import name changes from the 3.x scope. The compiler and the language server keep their own versions, since neither is published as a package. mx and live_mercury keep their own versions too.
What is planned
- Hypergraph: two more subpaths,
/hyperscript(the bindings for Hyperscript) and/hmr(hot replacement). - mx:
mx devalready hot-reloads, with its watcher and client (MX2); delivering Hypergraph's state-keeping swap through it waits on/hmr, above. The modules already build and test with mx; pnpm remains only for apps and tools undernode/. - For agents:
<page>.md,/agentsand search. (/llms-full.txtis served.) See For agents.
This site
Courses available now: Start, mx, Hyperscript, Mercury UI, Hypergraph, Content and Live Mercury. Their landing pages list the available lessons.
This site's application is mercury_lms 0.1.0, built with Elixir. It serves the Phoenix-rendered home at / and /ru, course pages by path, and plain-text companions for agents. mercury.jonnify.com is the public host; mercury-next.jonnify.com is the preview host.
