Couchbase Server 1.8.1 is now available.
- Rebalance improvements included in 1.8.1 optimize the movement of data when adding and removing the same number of nodes by moving data directly between the nodes being switched out. This enhancement puts customers in a position to proactively manage their application for all kinds of upgrades and maintenance reducing the impact on the rest of the cluster.
- Management of the memory allocated within the system has been improved. This increases stability of the system as a whole. In addition to this, a few new memory usage statistics have been added to our monitoring console.
- Several significant bugs related to rebalance and cluster stability have been fixed. The detailed release notes can be found here.
