Dear TVM community,

This is a call for vote to release Apache TVM version v0.25.0.

This v0.25.0.rc1 candidate supersedes v0.25.0.rc0, incorporating additional commits merged onto the release branch since rc0.

Release highlights:

  • Deeper tvm-ffi integration: the arithmetic Analyzer is now a tvm-ffi Object, structural APIs and IRModule JSON serialization are routed directly through tvm-ffi, and related FFI/header cleanups across the codebase.
  • TIRx infrastructure bring-up: initial TIRx infra with op-dispatch / codegen / TVMScript follow-ups and updated scoped ops and CUDA launch bounds.
  • Major Relax TFLite frontend expansion: LSTM / RNN / SVDF, Conv3D and CONV_3D_TRANSPOSE, REDUCE_WINDOW, quantized import via QDQ decomposition, resource variables / static hashtables, embedding-lookup-sparse, segment ops, and StableHLO + control-flow multi-subgraph support.
  • Relax ONNX correctness and ONNX Runtime parity: NaN/Inf handling for Sign / Cast / Clip / Div, RMSNormalization (opset 23), TopK scalar-K, Gather negative indices, ScatterElements reduction, NonMaxSuppression defaults, plus systematic ONNX backend tests.
  • Relax PyTorch fixes: segfault in from_exported_program with index_put_, correction in std/var, multi-axis flip, logical_not, and integer pow decomposition.
  • TIR / codegen: cooperative_tensor builtins with a metal.cooperative_tensor storage scope; CUDA fast-math intrinsic lowering gated behind a target/PassContext option; LLVM transcendental functions (sinh/cosh/atan/asin/acos/erf) routed through libm; Vulkan barrier fix.
  • Arithmetic robustness: memoized IntervalSet variable relaxation to avoid exponential blowup, and a canonical-simplify correctness fix.
  • Runtime / build: device runtime modularized into per-backend DSOs.
  • WebGPU/WASM: OPFS synchronous access handles and committed records, and persistent URL→hash mapping across page loads.
  • Security: fix missing exported flag in AndroidManifest; bound RPC tracker message size.

    Hello folks, I added a cmake fix into rc1 that only affects wheel packaging build. Since this patch does not affect most of the cases, I retagged v0.25.0.rc1 to move it one commit forward.

    Wheel install check for v0.25.0.rc1 — PyPI.

    Pre-release wheels are also published on PyPI for testing:
    pip install --pre apache-tvm==0.25.0rc1

    All four platform wheels published for apache-tvm==0.25.0rc1 (macOS arm64, Linux x86_64 + aarch64 manylinux_2_28, Windows AMD64). Installed the Linux x86_64 wheel in a clean venv — dependencies (including apache-tvm-ffi) resolve automatically, no source build:

    $ python3 -m venv venv && . venv/bin/activate
$ pip install apache-tvm==0.25.0rc1
...
Successfully installed apache-tvm-0.25.0rc1 apache-tvm-ffi-0.1.12 ...
$ python -c "import tvm; print(tvm.__version__)"
0.25.0rc1

    LGTM — wheel installs with the declared dependencies (apache-tvm-ffi>=0.1.12) and imports at the expected version. (It is a pre-release, so a bare pip install apache-tvm still resolves the latest stable; testers opt into the RC by pinning ==0.25.0rc1 or using --pre.)
