  codebase: "Clad"
  version: "v2.4"
  description: |
    Clad 2.4 is now compatible with clang-12 through clang-22, having ported to
    LLVM 22 and shifted its support window to the last ten major releases
    (clang-11 has been dropped). This release strengthens both forward and
    reverse modes with OpenMP critical directive support, reverse-mode handling
    of member access on call results, and the ability to redefine builtin custom
    derivatives. CUDA support advances with tape offloading to VRAM and
    device-callable tape element destruction. A major theme is robustness: a
    graceful fallback when differentiating parameterless functions, a
    correctness fix for TBR analysis that was silently producing wrong
    derivatives, and an extensive round of memory-safety cleanup—scope-leak
    fixes, use-after-poison repairs, and explicit ownership—surfaced by new
    LLVM 22 AddressSanitizer CI coverage. Static-library builds now skip backend
    pass registration, fixing rootcling dictionary generation in ROOT.

  codebase: "Clad"
  version: "v2.3"
  description: |
    Clad 2.3 is now compatible with clang-11 through clang-21. This release
    brings substantial improvements across both forward and reverse modes,
    including expanded custom derivative support, new derivatives for standard
    library functions like std::beta, std::expint, and std::comp_ellint, and
    better handling of lambdas and nested differentiation. Reverse mode gains
    basic OpenMP support, reduced overhead by skipping unnecessary reverse_forw
    passes when custom pullbacks are available, and important correctness fixes
    for nested Hessian computations and complex record adjoints. A major
    highlight is the new dual-mode tape memory system, offering an in-memory
    RAM-disk backend via mmap with automatic disk offloading, plus hooks for
    user-defined tape implementations. Error estimation has been unified with
    reverse mode behind a cleaner function-based interface, CUDA support is
    stronger thanks to compute-sanitizer integration, and nearly 40 tracked
    issues have been resolved.

    bringing smarter handling of loops, assignments, and method calls, alongside
    the new clad::restore_tracker for functions that modify their
    inputs. Forward mode gains static scheduling for Hessians and higher-order
    derivatives, while CUDA support expands with custom derivatives for key
    Thrust algorithms such as reduce, transform, and transform_reduce, plus
    optimizations that reduce unnecessary GPU atomics. The release also
    strengthens error estimation, simplifies adjoint initialization, improves
    tape efficiency, and enhances diagnostics. With a migration to C++17,
    support extended up to clang-21, and numerous bug fixes, Clad 2.1 delivers
