• Boost.Math 1.91.0.
  • Fixes <cmath>: Special Math ellint_2() produces wrong result when angle is close to 2 * pi #6152 / DevCom-10383094 / VSO-1830422.
• actions/checkout v7.
• Node.js 26.4.0.
• New pools.
• Internal toolset update: Remove tuple workaround for VSO-2826400.
• Internal toolset update: __cpp_lib_is_implicit_lifetime is always available in C++23 mode.

Pull request overview

This PR performs a routine STL toolset update, advancing the required compiler/tool versions and removing TRANSITION workarounds that are no longer needed now that the minimum MSVC compiler is 19.51. Now that the minimum supported MSVC (19.51), Clang 22, and EDG all support the relevant builtins, the #ifdef __cpp_lib_reference_from_temporary, #ifdef __cpp_lib_is_implicit_lifetime, and related _MSC_VER >= 1951 guards are deleted from the core headers, and the feature-test macros are now defined unconditionally in C++23 mode. It also bumps infrastructure (CUDA 13.3, Python 3.14.6, PowerShell 7.6.3, Node 26.4.0, actions/checkout@v7, new pools/locations) and drops a Windows SDK /analyze C28285 suppression that the SDK has fixed.

Changes:

• Raise compiler/tool minimums (MSVC 19.51 in yvals_core.h / 19.52.36510 in build, CUDA 13.3, Python 3.14.6) and remove now-obsolete TRANSITION workarounds in tuple, utility, type_traits, memory, and yvals_core.h.
• Update CI/provisioning toolchain: PowerShell 7.6.3, CUDA 13.3.0, actions/checkout@v7, Node >=26.4.0, cycled pool names/locations.
• Mark make_unique.array.pass.cpp as passing for MSVC and refresh TRANSITION comments to reference GH-6169.
