[Aerospike Go client version 5.6.0](http://www.aerospike.com/download/client/go/notes.html#5.6.0)was released on September 17, 2021.

**[IMPORTANT NOTE] A bug might occur when a client performing a scan hits a “Partition Unavailable” during an unstable cluster (in both high availability (AP) and strong consistency (CP) modes). The client aborts the scan and puts the connection back into the pool, which might cause unprocessed results to be sent to a different transaction (of the same client), possibly resulting in incorrect application behavior. We strongly recommend that you upgrade to the Go client 5.10.0 at the earliest opportunity.**

- The code resides in the v5 branch, and is available via the import [github.com/aerospike/aerospike-client-go/v5](http://github.com/aerospike/aerospike-client-go/v5)

#### Bug Fixes

- [CLIENT-1605] - Invalidate Session Token on unsuccessful login, Copy token from the connection buffer, Consider Tend interval in session expiration calculations.
