Version 7.2 latest refresh TR2 was released in May 2015

With 7.1, IBM started delivering new updates to the operating system via Technology Refreshes, where number 10 was released in May 2015.

The latest version of IBM i is 7.2, announced on April 28, 2014 and released on May 2, 2014 (Version Support Schedule).

When IBM announced the new Power Systems line of servers on April 2, 2008, they renamed the operating system from i5/OS to IBM i[3] and changed the version identifier format from VxRxMx (Version, Release, Modification, e.g. V6R1M0) to the more standard format (e.g. 6.1).

Version

In 2014, IBM ported Node.js to IBM i.[2]

In 2013, IBM and PowerRuby Inc. announced PowerRuby as a commercially supported port of the Ruby programming language and the Ruby on Rails Web application framework for IBM i. PowerRuby will be offered as a free download to be installed on customer machines.

In 2011, IBM and Zend Technologies announced Zend DBi as replacement for the MySQL on IBM i support with a first General availability release in 2012.

In 2007, IBM and MySQL AB announced a joint technology and reseller agreement to bring support for the MySQL open source database and DB2 for i as a certified MySQL storage engine to the IBM i platform, which was later in 2011 dropped by MySQL AB.

In 1999, IBM introduced logical partitioning (LPARs) with i5/OS to support multiple virtual systems on a single hardware footprint.

The IBM i Access licensed product includes iSeries Navigator, a client-based and web-based graphical tool for administration of the system, database, Apache web server, and WebSphere Application Server. IBM Systems Director Navigator for i now can be used to manage target servers running IBM i 5.4, 6.1 or 7.1 from a single browser environment with the IBM i 7.1.

Another peculiar feature is that this system was one of the earliest to be object-based. Unlike traditional OSes like UNIX and Windows NT there are no files, only objects of different types. It implemented one of the earliest-known systems for persistent objects. Further, the objects persist in very large, flat virtual memory, called a single-level store.[1]
