"The Free Software Foundation today released the final version of the new GNU General Public License, GPLv3. Novell welcomes and supports GPLv3 and we appreciate the collaborative process that led to its conclusion."

"Microsoft made a few mistakes in the Novell-Microsoft deal, and GPLv3 is designed to turn them against Microsoft, extending that limited patent protection to the whole community," explains GPLv3 co-author Richard M. Stallman.

In part 4 of a 5 part series on the new version of the most commonly used free/open source license, today we take a look at one of the reasons it took so long to create–the Microsoft/Novell patent deal.

Several large software companies seem satisfied with GPLv3, albeit cautious about adopting it (as corporations are wont to do). IBM intends to release some software under GPLv3, and MySQL says it will switch if GPLv3 is adopted widely.

Microsoft denies that it has anything to do with GPLv3 or vice versa. Novell, however, is making it clear that it will be supporting SUSE Linux Enterprise Server in the future, including any components, such as future versions of Samba, that are licensed under GPLv3.

Stallman added that it's extremely important for Free Software users to upgrade their licenses to GPLv3 so that Novell will eventually put in the new version and the community will get this benefit.

Stallman advised viewers to be wary of those that advise against moving to GPLv3.

In version 3 of the GNU General Public License (GPLv3), the term "the Program" means one particular work that is licensed under GPLv3 and is received by a particular licensee from an upstream licensor or distributor. The Program is the particular work of software that you received in a given instance of GPLv3 licensing, as you received it.

"The Program" cannot mean "all the works ever licensed under GPLv3"; that interpretation makes no sense, because "the Program" is singular: those many different programs do not constitute one program.

In particular, this applies to the clause in section 10, paragraph 3 of GPLv3 which states

"Microsoft cleared the air July 5 on its obligations to GNU General Public License Version 3 support, declaring it will not provide support or updates for GPLv3 under the deal it penned in November with Novell to administer certificates for the Linux distribution."

"For all that a great deal of attention was given to the arrival of the GPLv3 (Gnu General Public License, version 3), few software developers announced plans to move their programs to this new license. Now, open-source programmers are beginning to give the new license a try."
