That URL always points to the latest. But all the agreed changes are
publicly available as bugzilla entries.

It's well-defined in XSLT 2.0 which prefix you get. The rule

"A namespace node whose string value is a target namespace URI is copied to
the result tree, whether or not the URI identifies an excluded namespace."

means that in normal circumstances (that is, when the same namespace
bindings are in scope for the xsl:namespace-alias element and the literal
result element) you will get the result-prefix.
