v3.1.0
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.
NOTE: Please refer to the V3 Migration Guide for details on updating existing applications using v1.x.y or v2.x.y.
Default Retry Policy Changes
All libraries except Bigtable, PubSub, Spanner, and Storage have had their default maximum retry policy duration reduced from 30 minutes to 10 minutes.
