RcppBandicoot 4.0.1.1

  • Upgraded to bandicoot 4.0.1: "Bandwidth Glutton" (2026-05-08)
    • Fixes for compiler warnings.
    • Robustness fixes for unit tests.

RcppBandicoot 4.0.0.1

  • Upgraded to bandicoot 4.0.0: "Bandwidth Glutton" (2026-04-24)
    • Major overhaul of the internal meta-programming framework, allowing automatic fusion of many operations into a single GPU operation.
    • Preliminary, experimental support for the Vulkan backend.
    • New .is_symmetric() and .is_sympd() member functions.
    • Bug fixes for in-place matrix multiplication and backend memory safety.
    • Various optimisations for better expression handling.

RcppBandicoot 3.1.0.1

  • Upgraded to bandicoot 3.1.0: "This Coffee Is Poorly Roasted" (2025-12-10)
    • Non-contiguous submatrix views: Mat.elem(v), Mat.submat(rows, cols), Cube.elem(v), Mat.rows(rows), Mat.cols(cols).
    • Use NVRTC PTX compilation when the card architecture is too new for the installed NVRTC version.
    • Install into /usr/local/ by default on Linux/macOS systems.
    • New COOT_TARGET_OPENCL_VERSION configuration macro to suppress OpenCL compilation warnings.
    • New coot_backend() to report the selected backend.
    • Bug fix for operations on mixed matrix or cube types.
  • Kernel sources are now installed under inst/include/bandicoot_bits/ks/ (renamed from kernels/) to avoid R CMD check path-length warnings (#26).
  • Package updates following upstream 3.1.0: configure and Makevars refresh, COOT_KERNEL_SOURCE_DIR now appends kernels/, and an OpenCL file computation correction that mirrors upstream MR 193 (#17).
  • Suggest a sensible default for COOT_TARGET_OPENCL_VERSION during configuration (#11, closes #9).

RcppBandicoot 3.0.1.1

  • Upgraded to bandicoot 3.0.1: "Extreme Cable Organization" (2025-11-19)
    • Fix for missing cl_half.h header on macOS.
    • Fixes for compilation warnings on gcc and clang.
    • New COOT_KERNEL_SOURCE_DIR macro to allow kernels to live in a custom location for downstream packaging.

RcppBandicoot 3.0.0.1

  • Upgraded to bandicoot 3.0.0: "Extreme Cable Organization" (2025-11-14)
    • Initial support for the fp16 half-precision type.
    • Optimisations and simplifications for on-demand kernel compilation.
    • Fix backend initialization with CUDA toolkit version 13.
    • Support for CLBlast as a BLAS implementation for the OpenCL backend.
    • Fixes for OpenCL+OpenMP compilation.
    • Bug fixes for warnings in OpenCL and CUDA kernels.
    • Kernels are now compiled on-demand instead of all at once.
    • Support for char/short matrices and convenience u8/s8/u16/s16 typedefs.

    • .replace() member function for matrices and cubes.

RcppBandicoot 2.1.1.1

  • Upgraded to bandicoot 2.1.1: "Flat Tire" (2025-05-03), which resolves a minor release issue in 2.1.0. Incoming upstream changes (from 2.1.0) include:
    • .is_finite(), .has_inf(), and .has_nan() member functions for matrices and cubes.
    • .copy_size() member function for matrices and cubes.
    • min(), max(), index_min(), and index_max() for cubes.
    • Constructors for Mat, Col, and Row that accept strings and std::vectors.
    • Element initialisation that handles nested initialiser lists.
    • Bug fix for copy and move operators for Cube and Mat aliases.
    • Bug fix for diagmat() matrix multiplication on subviews.

RcppBandicoot 2.0.0.1
