### New API for creating connections to Accumulo
-A fluent API for clients to build `Connector` objects was introduced in
[ACCUMULO-4784].
-The new API deprecates `ClientConfiguration` and introduces its own properties
-file called `accumulo-client.properties` that ships with the Accumulo tarball.
+A fluent API for creating Accumulo clients was introduced in [ACCUMULO-4784]
and [#634].
+The `Connector` and `ZooKeeperInstance` objects have been deprecated and
replaced by
+`AccumuloClient` which is created from the `Accumulo` entry point. The new API
also deprecates
+`ClientConfiguration` and introduces its own properties file called
`accumulo-client.properties`
+that ships with the Accumulo tarball. The new API has the following benefits
over the old API:
+ * All connection information can be specifed in properties file to create
the client. This was not
+ possible with old API.
+ * The new API does not require `ZooKeeperInstance` to be created first
before creating a client.
+ * The new client is closeable and does not rely on shared static resource
management
+ * Clients can be created using a new Java builder, `Properties` object, or
`accumulo-client.properties`
+ * Clients can now be created with default settings for `BatchWriter`,
`Scanner`, etc.
See the [client documentation][clients] for more information on how to use the
new API.
