New release for msgpack-c?
CMake 4.0 is out now and msgpack-c cannot be compiled with it on Gentoo due to cmake <3.5 support being dropped.
It seems that there is no practical way to support both cmake < 3.5 and 4.0 It is a time to drop cmake < 3.5 support. Most of platform has cmake >= 3.5.
| Distro | Support Status (as of 2025) | Default CMake Version (example) |
|---|---|---|
| Ubuntu 16.04 | ESM only (regular support ended) | 3.5.1 |
| Ubuntu 18.04 | ESM (Extended Security Maintenance) | 3.10.2 |
| Ubuntu 20.04 | LTS (Long Term Support) | 3.16.3 |
| Debian 9 (Stretch) | EOL (End of Life) | 3.7.2 |
| Debian 10 (Buster) | LTS | 3.13.4 |
| CentOS 7 | Near EOL (June 2024) | 2.8.12 (*3.x available via SCL) |
| RHEL 7 | Extended support | 2.8.12 (*3.x available via SCL) |
| RHEL 8 / 9 | Actively supported | 3.11+ / 3.20+ |
| Arch Linux | Rolling release | Latest (always 3.29 or newer) |
| Alpine | Lightweight distro | 3.27.6 (as of 2025 edge) |
I will create the PR for both C and C++, then release them.
