pub const RELEASE_INDEX_SCHEMA_VERSION: u32 = 3;Expand description
Signed release-index schema understood by independent updaters.
v3 is the current frozen stable schema. It adds an explicit target_libc
field (gnu/musl) to Linux runtime artifacts so libc variants of the
same OS+arch are disambiguated deterministically. v3 is a versioned schema:
a v1.1.0 reader (whose validator requires RELEASE_INDEX_SCHEMA_VERSION == 2) rejects it at the schema boundary (fail-closed) rather than
naive-matching gnu and musl builds to the same OS+arch and failing
ambiguously.
