Downstream users should note that these release notes cover some changes already included in the 0.16.0 non-production release.
Incompatible Changes

(#1340)
- ❗ Azure Document DB has been removed (#1295)
- ❗ JDBC binding now semicolon for sharding (#1233)
Known Issues
- The mongodb binding does not honor the maxPoolSize=XX parameter and instead opens a connection per client thread. (see #317)
- Mongodb binding use with AWS DocumentDB requires manually converting SSL CA format (see #1314)
- Datastore drivers that lack timeouts may result in YCSB failing to honor the maxexecutiontime parameter. (see #618)
- "Latest" distribution does not work properly on update transactions. (see #640)
- Accumulo client currently always claims success even when the record it's supposed to operate on (e.g. for a read) doesn't exist. (see #699)
- JDK 9 and JDK 10 are not supported. (see #704)
- ArangoDB client bindings fail to work with ArangoDB authentication (see #1155)
- HBase 2.0 client bindings doesn't include an slf4j logging-binding and so doesn't provide log messages from the client library (see #1173)
- The Accumulo client bindings do not work with kerberos enabled clusters (see #1211)
- Memcached update deletes all fields except the one updated (see #1358)
- Data integrity verification doesn't check the number of fields. (see #1359)
- Workload D reports read failures when used with client side batched inserts (see #1356)
