v4.1.1

May 30, 2026 · GitHub ↗

A pure install-fixes release. v4.1.0 shipped the packages, but several of the documented install paths didn't actually work on a clean machine — the Homebrew build failed in the sandbox, the apt repo's signing key was never published, the MSYS2 download link pointed at a filename that doesn't exist. v4.1.1 makes every install command in the README work end-to-end, on all three platforms.

No library or API changes. If v4.1.0 already installed and built for you, nothing here affects your code — upgrade only if you hit one of the install problems below.

Fixed

  • brew install now works. The v4.1.0 formula died inside Homebrew's build sandbox — CPM/FetchContent tried to fetch BS_thread_pool over the network at build time, which the sandbox blocks. Those build deps are now vendored into the formula, so it builds offline (#288)
  • apt install no longer fails signature verification. The signed APT repo never exposed its public key, so apt update rejected it with NO_PUBKEY 7C5B392E…. The release now publishes the signing key (gempba-archive-keyring.gpg) alongside the index, so the documented signed-by= setup resolves (#286)
  • Dropped an unused OpenMP dependency the macOS formula pulled in for nothing (#289)

Docs

  • Rewrote the README's pre-built-package install instructions — every platform's block was broken or misleading (#286):
    • APT — added the one-time key-trust + repo-registration steps before apt install.
    • MSYS2 — the old releases/latest/download/<fixed-name> link 404'd (release asset names carry the version); now points at the Releases page + pacman -U.
    • Homebrew — fixed the literal <owner> placeholder, and clarified that both flavors install side by side (only one is linked at a time; each project points at $(brew --prefix gempba) / gempba-mpi).
    • Named the two flavors (mt / mpi / mp-mpi) up front so the section's recurring terms map to just two things.

Build / CI

  • The Homebrew formula is now built and brew test-ed on a real macOS runner on every PR and release, so a non-installable formula blocks the release instead of shipping (#292)
  • prepare-release bumps the Homebrew formula templates in lockstep with the other manifests — and actually stages them, so the bump lands on the prep branch (#297)
  • Hardened the macOS formula-verify job: pinned Homebrew off mid-run auto-update (which broke its ephemeral tap) and serialized the two-flavor matrix so they stop colliding on the shared prefix (#303)
