# Release History

### 2.0.0 / 2020-08-06

This is a major update that removes the "low-level" client interface code, and
instead adds the new `google-cloud-bigtable-v2` and
`google-cloud-bigtable-admin-v2` gems as dependencies. The new dependencies
are rewritten low-level clients, produced by a next-generation client code
generator, with improved performance and stability.

This change should have no effect on the high-level interface that most users
will use. The one exception is that the (mostly undocumented) `client_config`
argument, for adjusting low-level parameters such as RPC retry settings on
client objects, has been removed. If you need to adjust these parameters, use
the configuration interface in `google-cloud-bigtable-v2` and
`google-cloud-bigtable-admin-v2`.

Substantial changes have been made in the low-level interfaces, however. If you
are using the low-level classes under the `Google::Cloud::Bigtable::V2` or
`Google::Cloud::Bigtable::Admin::V2` modules, please review the docs for the
new `google-cloud-bigtable-v2` and `google-cloud-bigtable-admin-v2` gems.
In particular:

* Some classes have been renamed, notably the client classes themselves.
* The client constructor takes a configuration block instead of configuration
  keyword arguments.
* All RPC method arguments are now keyword arguments.
