CHANGELOG: document incoming 1.10.0
+v1.10.0
+===
+
+This is a small release that contains one bug fix, one new feature, and
+improvements in log lines, and improvements to work around AWS MSK being a bit
+odd with SASL reauthentication.
+
+Previously, the client's sticky partitioners actually did not preserve
+stickiness because the client did not attach previous-partitions when rejoining
+the group. That is now fixed.
+
+The new feature, `ConsumePreferringLagFn`, allows you to have some advanced
+reordering of how to consume. The recommended way of using this option is
+`kgo.ConsumePreferringLagFn(kgo.PreferLagAt(50))`, which allows you to favor
+laggy partitions if the client is more than 50 records behind in the topic.
+
+The kadm module is also released with v1.4.0, which contains new APIs to find
+coordinators for groups or transactional IDs, and an API to fetch API versions
+for all brokers in the cluster.
