New (and improved?) GPL v 3
The Free Software Foundation (FSF) has announced the release of version 3 of the GNU General Public License. The FSF had issued various drafts before now of this version 3 and sought consultation on the provisions before reaching a final version.
Those familiar with the previous version 2 will know that the General Public Licence is the most widely used licence for open-source software. This new version carries with it some key amendments since version 2, including a prohibition on the use of digital rights management software within GLP v 3 licensed programs to prevent modification of those programs (a process known as tivoisation by some). This particular change is seen as controversial by many, see comments made by Technollama.
This new version also tries to support the aim of open source software systems to guarantee freedom to every user to use, run, modify etc the program in question. No users of GPL v 3 licensed software will be liable for infringing any patents owned by distributors or creators of all GPLv3 licensed programs by modification of the program and each user would be granted a patent licence (where necessary) in respect of use of such programs. This goes further than version 2 which did not grant this right expressly.
There is no need to worry about the new GPL v 3 where you are using GPLv2 licensed software, except where you are using a program which combines both GPLv2 licensed code with v3 licensed code. GNU advises making use of the new version, however, in cases where the new provisions may be useful.
