The current main branch and public release packages produced from revisions after 9440f08b6909ef2dc93dd483cfdcb4e1e86077d0 are licensed under the GNU General Public License v3.0 or later (GPL-3.0-or-later). The authoritative license text is the root LICENSE file.
The GPL applies to the ARSVIN project material covered by that license. Third-party components remain subject to their own licenses and notices.
Revisions up to and including commit:
9440f08b6909ef2dc93dd483cfdcb4e1e86077d0
were released under Apache-2.0 and remain available on branch:
archive/apache-2.0-final
Those historical grants remain effective for those earlier revisions. They do not make later changes or current release packages available under Apache-2.0.
The current branch intentionally does not carry a second Apache license file because current releases are not offered as an Apache-or-GPL choice.
A separate negotiated commercial license may be available for proprietary integration, OEM or white-label distribution, closed-source redistribution, private branches, warranty, support, training, and engineering services. See COMMERCIAL-LICENSE.md.
COMMERCIAL-LICENSE.md is an invitation to discuss terms. It is not itself an executed commercial license and grants no additional rights.
Commercial terms can cover only rights controlled by the relevant copyright holder. Historical grants, contributor-owned material, standards, and third-party dependencies remain subject to their applicable rights and notices.
Contributions submitted after 2026-07-14 require:

Software-license permissions do not automatically grant project names, logos, icons, artwork, or official-release branding. See TRADEMARK.md.
