=== Improvements
51+
* https://issues.couchbase.com/browse/JVMCBC-1163[JVMCBC-1163]:
52+
Dependencies have been updated.
53+
* https://issues.couchbase.com/browse/JVMCBC-1156[JVMCBC-1156]:
54+
The traffic tracing functionality has been enchanced to perform Wireshark-style dissection of portions of the KV protocol.
55+
* https://issues.couchbase.com/browse/JCBC-1984[JCBC-1984]:
56+
KV range scan functionality (`collection.scan()`) added at @Stability.Volatile level.
57+
Users are encouraged to experiment with the feature and provide feedback ahead of its formal release in 3.5.0.
58+
* https://issues.couchbase.com/browse/JCBC-2018[JCBC-2018]:
59+
Make Core and CoreEnvironment Autocloseable.
60+
* https://issues.couchbase.com/browse/JCBC-2009[JCBC-2009]:
61+
Fixed an issue where ArraySetOptions was extending CommonDatastructureOptions incorrectly.
62+
* https://issues.couchbase.com/browse/JCBC-2021[JCBC-2021]:
63+
Diagnostics for an endpoint now include the state of the endpoint's circuit breaker.
64+
* https://issues.couchbase.com/browse/JCBC-2027[JCBC-2027]:
65+
The `ClusterEnvironment.Builder` methods that take a `Builder` are deprecated in favor of the overloads that take a `Consumer<Builder>`.
66+
For example, `ioConfig(IoConfig.Builder)` is deprecated in favor of `ioConfig(Consumer<IoConfig.Builder>)`.
67+
The methods that take a `Consumer<Builder>` are preferable because they allow customizing the config without clobbering the previous values.
68+
* https://issues.couchbase.com/browse/JCBC-2028[JCBC-2028]:
69+
`Cluster.connect` now throws an `IllegalArgumentException` if you pass a pre-built `ClusterEnvironment` and a connection string incompatible with the environment.
70+
Before this change, an incompatibility was logged as a warning, and the connection string scheme and parameters were ignored.
71+
`ConnectionStringIgnoredEvent` is now deprecated, since the SDK never publishes it anymore.
72+
** A pre-built environment without TLS enabled is incompatible with a connection string that specifies the secure `couchases` scheme.
73+
** A pre-built environment is incompatible with a connection string that has parameters.
74+
* https://issues.couchbase.com/browse/JVMCBC-1159[JVMCBC-1159]:
75+
Transactions now support upcoming server query_context changes.
76+
77+
=== Bugs
78+
* https://issues.couchbase.com/browse/JVMCBC-1157[JVMCBC-1157]:
79+
The SDK no longer rejects a `PersistTo` requirement in a bucket using the Magma storage engine. Before this change, the SDK would refuse the request because it misidentified Magma buckets as ephemeral (unable to persist documents).
80+
* https://issues.couchbase.com/browse/JVMCBC-1167[JVMCBC-1167]:
81+
If you call `CancellationErrorContext.getWaitUntilReadyContext()` on an error context that didn't come from a "wait until ready" request, the method is now guaranteed to return null instead of sometimes throwing a `ClassCastException`.
82+
* https://issues.couchbase.com/browse/JCBC-2024[JCBC-2024]:
83+
Fixed a memory leak in ManagerMessageHandler.
