+CHANGELOG
+=========
+
+5.4
+---
+
+ * Deprecate not setting the `delete_after_ack` config option (or DSN parameter),
+   its default value will change to `true` in 6.0
+
+5.3
+---
+
+ * Add `rediss://` DSN scheme support for TLS protocol
+ * Deprecate TLS option, use `rediss://127.0.0.1` instead of `redis://127.0.0.1?tls=1`
+ * Add support for `\RedisCluster` instance in `Connection` constructor
+ * Add support for Redis Cluster in DSN
+
+5.2.0
+-----
+
+ * Added a `delete_after_reject` option to the DSN to allow control over message
+   deletion, similar to `delete_after_ack`.
+ * Added option `lazy` to delay connecting to Redis server until we first use it.
+
+5.1.0
+-----
+
+ * Introduced the Redis bridge.
+ * Added TLS option in the DSN. Example: `redis://127.0.0.1?tls=1`
+ * Deprecated use of invalid options
+ * Added ability to receive of old pending messages with new `redeliver_timeout`
+   and `claim_interval` options.
+ * Added a `delete_after_ack` option to the DSN as an alternative to
+   `stream_max_entries` to avoid leaking memory.
