APACHE LICENSE 1.0 This is the original Apache License which applies only to older versions of Apache packages (such as version 1.2 of the Web server). APACHE LICENSE 1.1 The 1.1 version of the Apache License was approved by the ASF in 2000: ''The primary change from the 1.0 license is in the 'advertising clause' (section 3 of the 1.0 license); derived products are no longer required to include attribution in their advertising materials, but only in their documentation.'' APACHE LICENSE 2.0 The ASF approved an update to the Apache License in January, 2004. The stated goals of the license included ''making the license easier for non-ASF projects to use, improving compatibility with GPL-based software, allowing the license to be included by reference instead of listed in every file, clarifying the license on contributions, and requiring a patent license on contributions that necessarily infringe a contributor's own patents''. GPL COMPATIBILITY ISSUE The Free Software Foundation considers all versions of the Apache License incompatible with the Version 2 of the GNU General Public License . About version 2.0 of the Apache License, they say "''The Apache Software License is incompatible with the GPL because it has a specific requirement that is not in the GPL: it has certain patent termination cases that the GPL does not require. (We don't think those patent termination cases are inherently a bad idea, but nonetheless they are incompatible with the GNU GPL.)''" {Link without Title} The Apache Software Foundation is still trying to make its own determination about whether the Apache License 2.0 is compatible with the GPL as quoted here . The current draft of Version 3 of the GPL includes a provision (Section 7e) which allows it to be compatible with licenses that include patent retaliation clauses, including the Apache License.
