v0.5.2

macOS — .pkg installs WebLinked into /Applications; .dmg lets you drag it.
Apple Silicon only: CEF's binary distribution is per-architecture, so an Intel or
universal build needs a second distribution and a lipo pass.

Windows — -setup.exe installs with shortcuts; .zip is portable. x86_64.

Linux — portable .tar.gz, x86_64.

Output backends in these builds: NDI, OMT and the preview. The NDI SDK headers are
vendored and the runtime is bundled into the artefact, so NDI works on a machine that has
never installed it. DeckLink and AJA are located with find_package and silently disabled
when their SDKs are absent, which they are on hosted runners — build locally with those SDKs
installed to get SDI out. See docs/02-building.md.

Verification status is in docs/04-verification.md: NDI has been confirmed
end-to-end against a real receiver; DeckLink, AJA and OMT compile against the real
SDKs but have never been run against hardware.

Builds are unsigned. On macOS, after installing:

xattr -dr com.apple.quarantine "/Applications/WebLinked.app"

That step matters more here than usual — the app nests five CEF helper .apps, and
approving the outer bundle does not unquarantine them. A quarantined helper is
killed silently and looks like the renderer simply failing to start.
