[QGIS-Developer] Python 3.14 Support / Roadmap for QGIS and OSGeo4W on Windows

[Schäfer, Oliver]

Hello,

we are currently using QGIS 3.44.8 (Solothurn) in an enterprise environment. Our IT security department is receiving recurring Microsoft Defender vulnerability alerts related to the bundled Python 3.12 runtime.

We understand that QGIS for Windows relies on the OSGeo4W packaging and that individual vulnerabilities may already be patched there. To help us assess the situation and provide reliable feedback to our internal security team, we would appreciate clarification on the following points:

1. Is it currently possible to obtain or build a Windows version of QGIS using Python 3.14?

2. If not, is a migration of QGIS / OSGeo4W to Python 3.14 planned or being considered?

3. Are there any major technical blockers currently preventing such a migration?

4. Is there a roadmap or rough timeline for moving away from Python 3.12?

5. How are security vulnerabilities reported by Microsoft Defender typically addressed within the current OSGeo4W packaging?

Our primary interest is understanding whether Python 3.14 support is realistically expected in the foreseeable future, as this would help us evaluate the long-term handling of the reported vulnerabilities within our organization.

Thank you very much for your time and support.

Best regards,

Oliver Schäfer
