GPLv3\/Apache 2.0<\/strong>: Source code under Apache 2.0 can be used in a GPLv3 project because Apache 2.0 con\u00adtains fewer con\u00addi\u00adtions than GPLv3. There is no com\u00adpat\u00adi\u00adbil\u00adity the other way round or with other ver\u00adsions (e.g. GPLv2). Apache 2.0 con\u00adtains a pro\u00advi\u00adsion accord\u00ading to which patent rights may be revoked under cer\u00adtain con\u00addi\u00adtions. This con\u00adtra\u00addicts GPLv2. <\/p>\n\nGPLv3\/MIT<\/strong>: Due to the few restric\u00adtions, MIT source code can be used in GPLv3 projects with\u00adout any prob\u00adlems.
