This release brings the Elixir runtime to format version 1.1 of the wire standard. int_relative reconstructs on bignums and refuses a result outside 0 to 2^31 - 1 or not strictly above previous in every tier, the absolute tier included; a ranged int128 with min equal to max is legal and costs zero bits, so the int64 and int128 guards now agree; and the read stream now latches: a refusal hands back a failed stream, and every later read on it returns the error until the stream is re-initialized. The standard's conformance corpus is vendored and every vector runs in the test suite, so this runtime's verdict on hostile bytes is the same as every other runtime's; STANDARD.md is vendored for the first time, and both copies are checked against upstream in CI. The wire is unchanged: every golden pin passes untouched.
