Supersedes the 0.8.0 bump this PR started as, and folds in #262.

Why 1.0.0, and why now

Three identity changes for the artifact consumers link, kept in one release so they pay the cost once:

1.0.0. All three version files still read 0.6.0 — v0.7.0 was tagged without bumping them, so check-version.py has disagreed with
every tag since. This is also where an ABI/identity change belongs.

libminio. The library is built as libminio, matching the minio C++20 module that #262 renames (cherry-picked here, authorship
preserved). The CMake package, the exported target and the header directory stay miniocpp, so find_package(miniocpp) and
#include <miniocpp/…> are untouched. Meson's static library is renamed to match, so both build systems produce one name.

A real soname. Only VERSION was set, never SOVERSION, so CMake wrote the full version into the soname — as the deployed
libminiocpp.so.0.4.0 shows. Every release, patch releases included, therefore orphaned every binary already linked against its
predecessor. A 1.0 that keeps doing that promises a stability it does not deliver, so SOVERSION now carries the major alone:
the soname is libminio.so.1 and stays put across all of 1.x.

Verified

  • python3 check-version.pyminio-cpp version 1.0.0 is set correctly in all required files (fails on main as it stands).
  • Configured with -DBUILD_SHARED_LIBS=ON; the generated build names libminio.so.1.0.0, soname libminio.so.1, link name
    libminio.so, with no libminiocpp.so reference anywhere in the build tree.
  • grep over workflows, docs and packaging finds no remaining libminiocpp filename expectations. miniocpp.pc.in now emits -lminio.

What consumers have to do

Anything linking -lminiocpp moves to -lminio and rebuilds — a rebuild was required by any version bump anyway, given the old soname
policy. minio-go's RDMA lane is updated in minio/minio-go#2302, which pins this tag.

Note for deployments carrying a prebuilt copy: install the new file rather than replacing the old one if any already-linked binary is still
expected to load, since it records libminiocpp.so.<full version> as its dependency.

CI note on #262

Its three red lanes were all apt failures on the amd64 ubuntu-latest runners in the same minute — "Install dependencies" (a
dl.google.com chrome-repo hash mismatch), "Install GCC 14", "Install Clang 18" — with every arm64 twin green. Runner-image breakage, not
the module rename.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 49668

The change renames library and module outputs and publishes version metadata as 1.0.0, but the stated release target is 0.8.0 and Meson metadata remains at 0.6.0. These inconsistencies can produce incorrectly versioned build artifacts and packages, so the intended version should be aligned before merge.

Three changes that belong in the same release, because each one is a change of
identity for the artifact consumers link:

The version goes to 1.0.0. All three version files still read 0.6.0 -- v0.7.0
was tagged without bumping them, so check-version.py has disagreed with every
tag since.

The library is built as libminio, matching the `minio` C++20 module this release
also renames. The CMake package, the exported target and the header directory
stay `miniocpp`, so find_package() and #include lines are untouched.

SOVERSION carries the major alone. Until now only VERSION was set, which puts
the full version in the soname -- libminiocpp.so.0.4.0 -- so every release,
patch releases included, orphaned every binary already linked against its
predecessor. A 1.0 that keeps doing that would promise a stability it does not
have. The soname is now libminio.so.1 and stays put across 1.x.

Verified by the generated build: libminio.so.1.0.0, soname libminio.so.1.

Three lanes went red on minio#262 without its code being involved: all three failed
in apt steps on the amd64 runners in the same minute, one of them on a
dl.google.com chrome-repo hash mismatch, while every arm64 twin passed.

The RDMA lane's step was the clearest case -- it refreshed the apt index and
then installed nothing, so the only thing it could contribute was a failure.
It now just reports the CMake version.

The Meson lanes do need the index for gcc-14 and clang-18. They drop the runner
image's third-party lists first, since nothing here installs from them, and
retry once. `apt-get install` stays the gate, so an index that is genuinely
unusable still fails the job.

minio-cpp 1.0.0 builds the library as libminio (minio/minio-cpp#264), so the
link flag follows it. That release is also the first carrying
miniocpp_client_new_tls, which the change before this one calls, so the RDMA
lane pins it rather than v0.7.0 — which has neither.
