NOTICE: This repo will be merging with the googleapis/google-cloud-cpp monorepo in 60 days, around June 1, 2020. This change should not break any users who are using a released version. We expect this new monorepo organization to be better for our existing and new customers going forward. Please see googleapis/google-cloud-cpp#3612 for more details.

v1.0.0 Release (GA)

Breaking Changes

• feat!: add support for QueryOptions (#1351), this is a breaking
  change for any developers that used
  Connection::SqlParams::placeholder_do_not_use_name_will_change.
• feat!: implement SessionPool session refresh (#1425), this is a
  breaking change as the return type for
  SessionOptions::keep_alive_interval changed from
  std::chrono::minutes to std::chrono::seconds.

We believe the risk of developers being impacted by these changes
is small, but do apologize if this impacts you.
