Red Hat is dropping its free Linux product range and asking customers to migrate to its priced Enterprise Linux.
The company will end maintenance and errata support for Linux versions 7.1 through 8.0 on 31 December, and for the most recent version 9 on 30 April.
Red Hat Linux can still be downloaded free but the boxed versions that were on sale for between $39.95 and $149.95 are no longer available. No future versions will be developed.
Red Hat has characterised its free Linux product, which has been available since 1994, as "a general purpose, low-cost solution that ... attempted to be all things to all people".
By contrast, Enterprise Linux has been certified by a wide range of hardware and application software suppliers, Red Hat said.
The company is offering its users a choice between two upgrade paths, either to the stable Enterprise Linux product which starts at $179, or to its developer-oriented Fedora Project, which is available as a free download.
The Enterprise Linux product comes in three versions; AS for large corporate environments, ES for smaller offices and WS for workstation/desktop use. Each of these products is offered in basic, standard and premium editions depending on the level of support required.
The basic edition of Enterprise Linux WS costs $179, while the premium edition of AS for IBM zSeries and S/390 costs $18,000.
