MAX changelog updates:

  • Removed jump forward decoding (compute_ff_tokens) from structured output.
    The bitmask constraint alone ensures valid structured output, matching the
    approach used by vLLM and SGLang.
  • Fixed integer indexing into a graph tensor (e.g. x[0] on a (2, 3)
    tensor) failing graph compilation with
    mo.static.reshape op input and output elements do not match. A
    reshape-through-slice optimization pattern was incorrectly rewriting
    the slice + squeeze pattern produced by integer indexing, generating a
    reshape whose element count did not match the input.
    (Issue #6440)
