v3.0.0 - 2026-02
BREAKING CHANGES
As previously announced, google-cloud-cpp now requires C++ >= 17. This is
motivated by similar changes in our dependencies, and because C++ 17 has been
the default C++ version in all the compilers we support for several years.
We think this change is large enough that deserves a major version bump to
signal the new requirements. Additionally, we have decommissioned previously
deprecated API features and have also made some previously optional dependencies
required.
