[Aerospike Database version 5.4.0.1](https://www.aerospike.com/download/server/notes.html#5.4.0.1)was released on January 13, 2021. This major release contains a New Feature, Improvements, and a Bug Fix. - ATTENTION: Debian/Ubuntu users - if python2 is not installed, see the [Python Package Dependency for .deb Installers](https://discuss.aerospike.com/t/python-package-dependency-for-debian-deb-based-aerospike-tools-installers/7939) article. - Support for the XDR [`bin-policy`](https://www.aerospike.com/docs/reference/configuration/index.html?show-removed=1#bin-policy) value ‘only-specified’, has been removed. Users of ‘only-specified’ will likely want to switch to ‘changed-and-specified’. - Aerospike Server version 5.1 or later requires the operating system distribution’s **libcurl** shared object library. - Before upgrading to 5.0.0.4 or later, customers already running 5.0.0.3 in a cluster which is an active XDR destination (i.e. an XDR destination also acting as a source XDR or that may in the future act as a source XDR), may want to consider stopping all XDR traffic to the cluster. (Enterprise Only) - In the unlikely case of an upgraded 5.0.0.4 or newer node going down while 5.0.0.3 nodes are still running, those nodes would mistakenly ship XDR writes even if `forward` has not been explicitly enabled. - Enterprise Licensees may contact Aerospike Support for any questions before upgrading. - Cross-Datacenter Replication (XDR) running in Aerospike Server version 5.0 or newer can only connect to XDR destination clusters running versions 4.1 or newer. - **All nodes must be upgraded to Aerospike Server version 4.9.0.7 or newer** prior to upgrading to Aerospike Server version 5.0 or newer. - Aerospike Server version 5.0 or newer **will not** form a cluster with version 4.8 nodes or earlier. - When upgrading the Aerospike Server refer to the [Special Upgrades](https://www.aerospike.com/docs/operations/upgrade/aerospike/special_upgrades/index.html) documentation. - The Aerospike Server **will not start** if obsolete configuration parameters are set in the Aerospike configuration file (aerospike.conf). - Refer to: [Configuration parameters that must be removed for Aerospike Server version 5.0 or newer](https://www.aerospike.com/docs/operations/upgrade/aerospike/special_upgrades/50_removed_parameters.html) - **ATTENTION:** As of Aerospike Server version 4.9, expirations and evictions are disabled by default. - For expirations, [`nsup-period`](https://www.aerospike.com/docs/reference/configuration/index.html?show-removed=1#nsup-period) must be configured (new default is 0). - For evictions, the relevant [`high-water-disk-pct`](https://www.aerospike.com/docs/reference/configuration/index.html?show-removed=1#high-water-disk-pct)/[`high-water-memory-pct`](https://www.aerospike.com/docs/reference/configuration/index.html?show-removed=1#high-water-memory-pct)/[`mounts-high-water-pct`](https://www.aerospike.com/docs/reference/configuration/index.html?show-removed=1#mounts-high-water-pct) must be configured (new defaults are 0). - For details refer to the [`Namespace Retention Configuration`](https://www.aerospike.com/docs/operations/configure/namespace/retention/index.html) documentation. - CentOS Linux 8 End of Life is scheduled for December 2021. - For more information please refer to: [FAQ - CentOS Project shifts focus to CentOS Stream](https://centos.org/distro-faq/)
