1.0.0

API documentation: https://docs.couchbase.com/sdk-api/couchbase-cxx-client-1.0.0
Full Changelog: 1.0.0-dp.15...1.0.0

Enhancements

• CXXCBC-509: Allow to restrict replica set to selected server group. This feature allows to implement network optimization when traffic cost between server groups is higher than in the local group. In this case the application might select preferred server group in the connection options, and later opt-in for local operations during replica reads.
