Current revisions on main and current public release packages are licensed only under:
GPL-3.0-or-later
The GNU General Public License gives users permission to run, study, modify, and redistribute covered software subject to its terms, including source-availability obligations when conveying object code.
The final revision released under Apache-2.0 as the active project license is:
85d43a0fe58a5888a9e8008c168ab76d2333ea87
It is preserved on:
archive/apache-2.0-final
Revisions at or before that boundary retain the Apache-2.0 rights already granted. Those historical rights are not revoked. Later revisions and current binaries are not offered as an Apache-or-GPL choice.
Organizations requiring proprietary integration, OEM or white-label distribution, closed-source redistribution, private branches, contractual support, training, warranty, or engineering services may discuss a separate commercial agreement.
COMMERCIAL-LICENSE.md is an invitation to negotiate. It is not itself an executed license and grants no additional rights.
Commercial rights can cover only material and rights controlled by the relevant granting party. Third-party components, contributor-owned material, standards, and historical grants remain subject to their own terms.
New contributions require:
- affirmative acceptance of
CONTRIBUTOR-LICENSE-AGREEMENT.md; - a Developer Certificate of Origin sign-off on every commit;
- authority to submit the material, including any required employer or organizational approval; and
- documented provenance for any third-party or non-synthetic fixture.
Current portable packages must include:
LICENSE.txt
NOTICE.txt
COMMERCIAL-LICENSE.md
COPYRIGHT.md
TRADEMARK.md
THIRD_PARTY_NOTICES.md
Licensing.md
LICENSE.txt must contain GNU GPL version 3. A historical Apache license file must not be included in a current package in a way that suggests Apache-2.0 applies to the current binary.
Repository records document licensing intent and public release boundaries. They do not by themselves establish employer ownership, resolve invention-assignment or confidentiality duties, or determine rights in off-repository material. Significant commercial transactions should review the exact contributors, contracts, dependencies, trademarks, fixtures, and deliverables involved.
