Release notes for next release

Added

  • M0 scaffold: mix project, MLX 0.25.1 prebuilt fetch pipeline, Makefile wiring fine + MLX, Emily.Native NIF surface for tensor round-trip, application supervisor skeleton, smoke test suite.
  • M1 (partial) — Emily.Native op inventory. Shared headers in c_src/emily/ (dtype mapping, Tensor resource, helpers); per-category op files under c_src/ops/:
    • Creation: zeros, ones, full, arange, eye.
    • Cast: astype.
    • Unary elementwise: negative, abs, sign, floor, ceil, sqrt, rsqrt, exp, expm1, log, log1p, log2, log10, trig/inverse-trig/hyperbolic family, sigmoid, erf, erfinv, square, reciprocal, logical_not, bitwise_invert, isnan, isinf, isfinite, conjugate, real, imag, stop_gradient, round (with decimals).
    • Binary elementwise: add, subtract, multiply, divide, floor_divide, remainder, power, maximum, minimum, logaddexp, arctan2.
    • Compare: equal, not_equal, less, less_equal, greater, greater_equal.
    • Logical: logical_and, logical_or.
    • Bitwise: bitwise_and, bitwise_or, bitwise_xor, left_shift, right_shift.
    • Reductions (axes + keepdims): sum, mean, prod, max, min, all, any, logsumexp; plus var/std with ddof, argmax/argmin, cumulative cumsum/cumprod/cummax/cummin.
    • Shape: reshape, transpose, squeeze, expand_dims, broadcast_to, concatenate, stack, flatten, tile, swapaxes, pad, repeat.
    • Indexing: slice, take, where.
    • Linalg: matmul, tensordot, outer, inner.
  • Emily.Native.to_binary/1 now routes through mx::contiguous so strided views (transpose/slice/swapaxes/broadcast) materialize correctly.
  • Makefile compiles c_src/**/*.cpp recursively.

Notes

  • Ops files use anonymous namespaces to prevent NIF function names (sin, log1p, sqrt, ...) from colliding with C math-library symbols pulled in by MLX headers.
  • Deferred to later iterations of M1: sort/argsort, clip, slice_update, take_along_axis, scatter*, convolutions, hadamard_transform, random ops, FFT, quantized ops, memory-stats/soak tests. Tracked for M1 completion before moving to M2 (Backend).
