earlier versions of the management console, there was an option that was available to specify the location of a log file on a remote node. This could be used to read / write to an arbitrary file on that remote node. For this reason, it was not advisable to run the application server / node agent processes with root privileges, and starting with v6, security configuration defaulted out of the box to a secure state (even if this meant that enabling desired functions required manual changing of the defaults). Originally, all nodes of the cell were in a single domain for management as well as application security. However, starting with v6.1, there can be multiple security domains and administrative and application security can be separate. Many IBM products (such as IBM InfoSphere DataStage) use WebSphere Application Server as the base platform for their infrastructure. Version history IBM has shipped several versions and editions of WebSphere Application Server. In the first beta versions, WebSphere had been called Servlet Express. Although the versioning scheme x.1 and x.5 would usually indicate a minor release in the software industry, WebSphere v6.1 and v5.1 are major releases, just like WebSphere v8.5 and v3.5. WebSphere Liberty Versions WebSphere Liberty was introduced into WebSphere Application Server V8.5, originally referred to as the WebSphere Liberty Profile, with the same version numbering scheme as the rest of WAS. In 2016 IBM introduced a new fix pack numbering scheme for Liberty to reflect a move to continuous delivery of Liberty in a single support stream - after V8.5.5.9, the Liberty numbering scheme was rebased starting at 16.0.0.2 to reflect Year and Quarter of the Liberty fixpack release. A common level of WebSphere Liberty is distributed as part of the both Version 8.5 and Version 9.0 of WebSphere Application Server. The Liberty continuous delivery model was introduced to allow new capabilities and features to be delivered on a more frequent basis. Version 9.0 WebSphere Application Server V9.0 adds Java EE 7 and Java SE 8. This brought WAS Application Server traditional up to the same level of Java EE as WebSphere Liberty had offered since 2015. This was the first release of WAS to be made simultaneously available as both an on-premises offering and through WebSphere as a Service on IBM Cloud. WebSphere Liberty is increasingly the focus for new cloud native applications, with Liberty 16.0.0.2 being the version of Liberty
