Ahead of the next release, the workflows were audited for stale runner images, outdated action tags, and a vcpkg baseline that no longer matches what's preinstalled on the hosted runners.
Runner images
macOS: macos-13 (Intel, deprecated) → macos-latest (macOS 26, arm64). Cache key updated vcpkg-binaries-x64-osx → vcpkg-binaries-arm64-osx to match the new default triplet; the arm64 cache starts cold on first run.
Windows: windows-2022 → windows-latest (Windows Server 2025). That image ships Visual Studio Enterprise 2026 only, so the generator changes and the job is renamed vs2022 → vs2026:
- -G "Visual Studio 17 2022" -A "$msbuildArch"+ -G "Visual Studio 18 2026" -A "$msbuildArch"
x86/x64 MSVC toolsets are still present in the image, so the arch/libs/config matrix is unchanged. CMake on that image is 4.4.3, which knows the VS 18 generator.
Linux: already on ubuntu-latest; left as-is.
vcpkg
builtin-baseline → 04a9d8e5212d01ee1dd9478eadd9caade4f8b0d4, the vcpkg commit preinstalled on all three latest images (ubuntu-24.04, macOS 26, Windows Server 2025 all report "build from commit 04a9d8e521"), so VCPKG_INSTALLATION_ROOT and the manifest agree.
Action tags
actions/checkout (3d3c42e5… = v7.0.1) and actions/cache (55cc8345… = v6.1.0) are already pinned to the newest releases; unchanged.
Worth watching on this branch: the first Windows build under VS 2026 and the first macOS arm64 build.
